That is, the optometry device and other means may be connected via a shared server.

<Detection means>
In this embodiment, the optometric apparatus includes detection means (for example, detector 105). The detection means may detect contact between the optometrist and the subject.

As the detection means, a photographing means (for example, a camera equipped with an image sensor, etc.) capable of detecting contact between the optometrist and the subject may be used. In this case, contact between the optometrist and the subject may be determined by analyzing an image photographed by the photographing means.

Further, as the detection means, a sensor (for example, at least one of a light sensor, a pressure sensor, a load sensor, etc.) capable of detecting contact between the optometrist and the subject may be used. The detection means may detect that the optometrist is in contact with the subject based on a detection signal emitted when the optometrist comes into contact with the subject. As an example, when the detection means is a load sensor, when the load sensor detects an external load, the load sensor may convert the load into an electrical resistance value and output it. Contact between the optometrist and the subject may be detected based on whether or not a potential resistance value is output (in other words, whether or not a detection signal is output). For example, the detection means may detect that the optometrist is in contact with the subject when the potential resistance value is output.

In addition, when the optometry apparatus has a forehead rest for touching the forehead of the subject, the detection means is provided in the forehead rest, and even if it detects whether or not the forehead of the subject is brought into contact with the forehead rest. good. The detection means may detect that the subject's forehead has contacted the forehead rest when a load is detected from the forehead rest. Further, for example, when the optometry apparatus has a chin rest for placing the chin of the subject, the detection means is provided on the chin rest and detects whether or not the chin of the subject is placed on the chin rest. You may. The detection means may detect that the subject's chin has come into contact with the chin rest when a load is detected from the chin rest. Of course, when the optometry apparatus has both a forehead rest and a chin rest, the detection means may be provided on at least one of the forehead rest and the chin rest.

The determining means determines whether or not the eye to be examined is in a state where it can be examined. For example, the state in which the eye to be examined can be examined is a state in which it is possible to start the examination of the eye to be examined. For example, the subject's face may be fixed to the optometry device using a forehead rest. Further, as an example, the subject's face may be fixed using a chin rest. Further, as an example, the optometry device and the subject may be in a predetermined positional relationship.

The determining means may determine whether or not the eye to be examined is in a state where it can be examined, based on the detection result of the detecting means. For example, the determining means may determine that it is possible to start the examination of the subject's eye when the detecting means detects contact between the eye examination apparatus and the subject. More specifically, the determining means may determine that it is possible to start the examination of the subject's eye when the detection signal is emitted from the detecting means. Further, for example, the determining means may determine that it is impossible to start the examination of the subject's eye when the detecting means has not detected contact between the optometrist and the subject. More specifically, it may be determined that it is impossible to start testing the eye to be examined when no detection signal is emitted from the detection means.

<Output means>
In this embodiment, the optometry apparatus includes a first output means (for example, a control section 303). The first output means outputs determination information based on the determination result of the determination means. This allows the examiner to easily understand whether or not the subject is ready for examination.

The first output means may output notification information for notifying the examiner of the determination result as the determination information. In this case, the notification information includes information indicating the judgment result (that is, information indicating whether it is possible or impossible to start the examination of the subject's eye), information for guiding the examiner to the next action, etc. It may be.

The first output means may output such notification information to the remote control means. For example, the first output means may output the notification information as a message to a display means provided in the remote control means. Further, for example, the first output means may output the notification information by generating audio guidance on the remote control means. Further, for example, the first output means may output the notification information by lighting or blinking a lamp on the remote control means.

Of course, the first output means may output the notification information to a means different from the remote control means. For example, the first output means may output the notification information to a printer or the like for printing, or may output the notification information to a memory, a server, or the like for storage.

In this embodiment, the optometry apparatus includes second output means (eg, the control section 107 and the control section 303). The second output means outputs an instruction signal for instructing the next operation to at least either the optometric apparatus or the remote control means based on the determination result of the determination means. This allows the examiner to efficiently proceed with the examination of the subject's eye.

The second output means may output an instruction signal to the optometric apparatus. In this case, the instruction signal may be an instruction signal for causing the optometric apparatus to start alignment, an instruction signal for causing the optometric apparatus to start an examination, or the like. Further, the second output means may output an instruction signal to the remote control means. In this case, the instruction signal may be an instruction signal that causes a display device included in the remote control device to display a screen for configuring the optometry device, or the like.

In addition, in this embodiment, the optometry apparatus may have a configuration in which the first output means and the second output means are both used, or may have a configuration in which they are provided separately. Further, in the present embodiment, the optometry apparatus may be configured to perform either one of outputting the determination information by the first output means and outputting the instruction signal by the second output means, or may be configured to perform both. Good too.

In this embodiment, the optometry device may include alignment means. The alignment means aligns the eye to be examined and the optometry device. The alignment means may be configured to project an alignment index onto the anterior segment of the eye to be examined, and use the alignment index image to align the eye to be examined and the optometric apparatus.

In this embodiment, the optometric apparatus may include fundus photographing means. The fundus photographing means photographs the fundus of the eye to be examined. For example, the fundus photographing means may include at least one of an ophthalmological optical coherence tomometer, a scanning laser ophthalmoscope, a fundus camera, and the like. Of course, the fundus photographing means may have a configuration different from these configurations.

<Photography means>
In this embodiment, the optometry system includes a photographing means (for example, the photographing section 200). The photographing means photographs the examination room including the subject and the optometric apparatus. For example, the examination room may be a bright room for testing the subject's eye. For example, it may be a bright room for measuring the optical characteristics of the eye to be examined. Further, for example, the examination room may be a dark room for examining the eye to be examined. For example, it may be a dark room for photographing the anterior segment or fundus of the eye to be examined.

The photographing means may photograph the examination room as a moving image. That is, the photographing means may photograph the examination room in real time. Further, the photographing means may photograph the examination room as a still image. In this case, the photographing means may capture images at regular intervals (for example, every 5 seconds).

The photographing means may be capable of photographing the photographing room including the subject and the optometric apparatus under clear vision. Further, the photographing means may be capable of photographing the photographing room including the subject and the optometry apparatus under night vision. In this case, a night vision camera may be used as the photographing means. Examples of night vision cameras include high-sensitivity cameras that amplify sensitivity to light, infrared cameras that detect infrared rays emitted by objects, and the like.

For example, in the field of ophthalmology, a dark room is often created when examining the eye to be examined in order to reduce the influence of changes in ambient light such as illumination equipment in the examination room on the examination accuracy. As in the present embodiment, by enabling imaging under night vision, it is possible to observe the condition of the subject even in a dark room, and it is also possible to accurately test the subject's eye.

The photographing means may photograph the examination room so that the positional relationship between the examination room and the optometry equipment placed in the examination room (in other words, the layout of the examination room and the optometry equipment) can be grasped. For example, in this case, the photographing means may be arranged at a different position from the optometry apparatus so as to provide a bird's-eye view of the subject and the optometry apparatus. As an example, the imaging means may be placed in an examination room.

The photographing means may be placed at any position in the examination room as long as it can photograph the examination room including the subject and the optometric apparatus. For example, the imaging means may be placed above the examination room. This makes it easier for the imaging means to photograph the entire examination room, and it also becomes easier for the examiner to understand the state of the examination room using the image taken by the imaging means.

The imaging means may be placed in the center above the examination room. In this case, an omnidirectional camera (360 degree camera) or the like may be used as the photographing means. Further, the imaging means may be arranged at an upper corner of the examination room. In this case, as the photographing means, a directional camera, a camera with a swing function, etc. may be used. By disposing the photographing means above and at a corner of the examination room, the entire examination room can be easily photographed even when a simple camera is used.

<Remote control means>
In this embodiment, the optometry system includes remote control means (for example, remote control section 300). The remote control means may include an operation screen for operating the optometry apparatus and a display means (for example, a monitor 301) for displaying a photographed image taken by the photographing means. Further, the remote control unit may include a display control unit (for example, the control unit 303) that controls the display of the display unit and causes the display unit to display the operation screen and the photographed image. That is, the remote control means may include a display means and a display control means, and may be capable of guiding the subject to the examination position by observing the photographed image displayed on the display means. With this configuration of the optometry system, even if the examiner and patient are not in the same space, the examiner can issue appropriate instructions while observing the patient, allowing for efficient eye examination. You can proceed well.

The operation screen for operating the optometry device may be a screen used for testing the subject's eye using the optometrist. As an example, the operation screen may be a setting screen for performing various settings in the optometric apparatus. If the optometry device is an OCT device, a screen for setting the scanning position, scanning pattern, etc. of measurement light for acquiring OCT data may be displayed as the setting screen. Further, as an example, the operation screen may be a result screen showing the results of an examination using an optometrist. If the optometry device is an OCT device, a tomographic image generated from OCT data may be displayed as the result screen. Further, as an example, the operation screen may be an image of the eye to be examined, which is an image of the eye to be examined. When the optometry device is an OCT device, an anterior segment image photographed by an anterior segment imaging optical system included in the OCT device may be displayed as the eye image to be examined.

The photographed image photographed by the photographing means may be an image photographed to guide the subject to the optometry apparatus. For example, the image may be an image of the entire examination room, and may be an image in which the optometry apparatus and the subject can be observed. Alternatively, for example, the image may be an image of at least a portion of the examination room, and may be an image in which the optometrist and the subject can be observed.

The examination position to which the subject is guided may be the position of the optometric apparatus. Furthermore, the examination position to which the subject is guided may be a position away from the optometry apparatus. As an example, the examination position to which the subject is guided may be the position of a chair used with an optometry device, or the like.

<Display control means>
In this embodiment, the display control means included in the remote control means controls the display of the display means and causes the display means to display an operation screen. Further, in this embodiment, the display control means included in the remote control means controls the display of the display means to display the photographed image taken by the photographing means on the display means. For example, the display control means may control the display of the display means based on at least one of an operation signal manually input by the examiner, an operation signal automatically issued based on the operation of the optometry device, etc. good.

The display control means may control the display of the display means so that the operation screen and the photographed image are displayed on the same screen of the display means. In this case, the display control means may display the operation screen and the photographed image on the screen of the display means at the same timing. Further, in this case, the display control means may display the operation screen and the photographed image on the screen of the display means at different timings. For example, the display control means may be configured to display either the operation screen or the photographed image on the display means first, and display the other on the display means later.

For example, by displaying the operation screen and the photographed image on the same screen, the examiner can monitor a series of movements of the examinee (for example, The patient's behavior (e.g., the patient's behavior during the examination of the patient's eye, etc.) ) can be observed while operating the optometry device, and the eye to be examined can be examined efficiently.

In this embodiment, the remote control means may include a signal acquisition means (for example, the control unit 303). For example, the signal acquisition means acquires a switching signal for switching between the operation screen and the photographed image. The switching signal may be issued manually by the examiner's operation. Further, the switching signal may be automatically issued at a preset timing. As an example, the switching signal may be issued at the timing when the determining means determines that the eye to be examined is ready for examination. More specifically, it may be emitted at the timing when the subject's forehead comes into contact with the forehead rest, the timing when the subject's chin is placed on the chin rest, etc.

When the remote control means is configured to include such a signal acquisition means, the display control means switches and displays the operation screen and the photographed image on the screen of the display means based on the switching signal. The display on the display means may also be controlled. For example, the display control means may control the display of the display means based on the switching signal so that either the operation screen or the photographed image is displayed on the screen of the display means. For example, the display control means may delete either the operation screen or the photographed image based on the switching signal from a state in which both the operation screen and the photographed image are displayed on the same screen of the display means. , the display on the display means may be controlled. Further, for example, the display control means may add the other from a state in which either the operation screen or the photographed image is displayed on the screen of the display means, so that both the operation screen and the photographed image are displayed on the same screen of the display means. The display on the display means may be controlled based on the switching signal so that the display is displayed on the screen.

For example, by switching and displaying the operation screen and the photographed image on the screen, the examiner can easily give instructions to the patient while observing the screen where the operation screen and the photographed image are switched manually or automatically. The patient's eye can be examined.

<Assignment of operations to the operation unit that operates the optometry device>
In this embodiment, the optometry system includes a first operation section (for example, the operation section 101 and the monitor 106). The first operation unit is provided in the housing of the optometry device or near the optometry device, and operates the optometry device. For example, in this embodiment, the first operation section may be provided in the casing of the optometry apparatus. As the first operation unit, a user interface such as a mouse, joystick, keyboard, tablet terminal, controller, etc. may be used.

Further, in this embodiment, the optometry system includes a second operation section (eg, operation section 302). The second operation unit is provided at a location away from the optometry device, and operates the optometry device. For example, in this embodiment, the second operation section may be provided on the remote control means. As the second operation unit, a user interface such as a mouse, joystick, keyboard, tablet terminal, controller, etc. may be used.

<Setting means>
In this embodiment, the optometry system includes a first setting means (for example, the control unit 107). The first setting means assigns a first operation in the optometry apparatus to a first operation signal input from the first operation section. The first setting means may be configured to allocate one operation to the first operation section, or may be configured to allocate a plurality of operations.

Further, in this embodiment, the optometry system includes a second setting means (for example, the control unit 107). The second setting means assigns a second operation in the optometric apparatus to a second operation signal input from the second operation section. The second setting means may be configured to allocate one operation to the second operation section, or may be configured to allocate a plurality of operations.

That is, in this embodiment, the first setting means and the second setting means can appropriately allocate operations to the first operation section and the second operation section. In other words, the first setting means and the second setting means can appropriately set the operations for the first operation section and the second operation section.

The first operation and the second operation are at least one of the operations performed when examining the eye to be examined using the optometric apparatus. Examples include an alignment operation for aligning the optometry device and the eye to be examined, a photographing operation for photographing the eye to be examined, a setting operation for setting test conditions for examining the eye to be examined, an examination start operation for starting the examination of the eye to be examined, and a jaw movement. Examples include at least one of an adjustment operation to adjust the height of the stand, an adjustment operation to adjust the position of the forehead rest, and the like. Of course, the first operation and the second operation may be operations other than these. For example, there may be operations related to alignment between the optometrist and the subject's eye and examination of the subject's eye using the optometrist.

The first setting means and the second setting means may be set to assign at least some of the same operations in the optometry apparatus to the first operation section and the second operation section, respectively. In this case, the first action and the second action may all be the same. As an example, the alignment operation and adjustment operation may be assigned to the first operation section, and the alignment operation and adjustment operation may also be assigned to the second operation section. Further, in this case, the first action and the second action may partially overlap. As an example, the alignment operation and the photographing operation may be assigned to the first operation section, and the alignment operation and the adjustment operation may be assigned to the second operation section.

Further, the first setting means and the second setting means may be set so as to assign different operations in the optometry apparatus to the first operation section and the second operation section, respectively. That is, the first action and the second action may be different. As an example, the test start operation may be assigned to the first operation section, and the alignment operation may be assigned to the second operation section.

Note that, in the above example, the first setting means and the second setting means are configured to assign predetermined operations to the first operation section and the second operation section, respectively, but the present invention is not limited to this. The first setting means and the second setting means may be set so as to assign a predetermined operation subdivided to each of the first operation section and the second operation section. As an example, the first setting means may set the first operation section to assign horizontal and vertical movement movements of the alignment operation, and the second setting means may assign the movement operations in the left and right directions and the up and down direction to the second operation section. , a setting may be made to allocate the movement movement in the forward and backward direction of the alignment movement.

For example, in the optometry system of this embodiment, since the examiner operates the optometry device from a remote location, it is difficult to understand the sense of distance in the front-rear direction during alignment operations. By assigning the alignment operation for each movement direction to the first operation section and the second operation section, it is possible to reduce the possibility that the subject will come into contact with the optometry apparatus.

For example, the assignment of the first action and the second action by the first setting means and the second setting means may be set in advance. Settings may be automatically changed by acquiring operator information (described later). Of course, the examiner may be able to change the settings arbitrarily.

For example, by configuring the operation of the optometry device to be controllable using the first operation section and the second operation section, the operator who operates the optometrist (i.e., examiner, subject, assistant Appropriate actions can be assigned according to the location and skill of the person (e.g., person), the content of the action when examining the subject's eye, etc. The examiner can easily examine the eye to be examined without being present in the space where the optometrist is placed.

In addition, in this embodiment, when the optometry apparatus is equipped with the above-mentioned fundus photographing means, at least one of the first setting means and the second setting means receives an operation signal input from the first operation section and the second operation section. An operation for starting photographing by the fundus photographing means (in other words, a photographing start operation) may be assigned to the fundus photographing means. As an example, in the present embodiment, settings may be made such that the imaging start operation is assigned to the operation unit operated by the examiner, and the imaging start operation is not assigned to the operation unit operated by the subject. Therefore, even if the subject issues an operation signal to start imaging, malfunctions of the optometric apparatus are suppressed.

Furthermore, in the present embodiment, when the optometry apparatus includes the above-mentioned alignment means, at least one of the first setting means and the second setting means responds to the operation signal input from the first operation section and the second operation section. , an operation for positioning by the alignment means (in other words, an alignment operation) may be assigned. As an example, in this embodiment, the alignment operation may not be assigned to the operation section operated by the examiner, but may be set so that the alignment operation is assigned to the operation section operated by the subject. Alignment can be performed safely by having the examinee who is able to grasp the sense of distance between the examinee's eye and the apparatus perform the alignment operation.

<Operation control means>
In this embodiment, the optometry system includes an operation control means (for example, the control unit 107). The operation control means prohibits execution of the operation of the optometry apparatus according to the other operation signal when the operation of the optometry apparatus is executed according to one of the operation signals of the first operation signal and the second operation signal. .

For example, when the operation of the optometry device is being performed based on one of the first operation signal and the second operation signal, the operation control means prohibits the input of the other operation signal. It may also be configured to prohibit execution of the device's operations. Further, for example, the operation control means prohibits transmission or reception of the first operation signal or the second operation signal when the operation of the optometry apparatus is being performed by one of the operation signals. Accordingly, a configuration may be adopted in which execution of the operation of the optometry apparatus is prohibited. Further, for example, the operation control means may be configured to control the operation of the optometry apparatus when the operation of the optometry apparatus is performed by one of the first operation signal and the second operation signal. A configuration may be adopted in which the operation of the optometry apparatus is prohibited by prohibiting the execution of the operation signal.

Note that in this embodiment, the first setting means and the second setting means do not assign a predetermined operation to either the first operation section or the second operation section, so that the operation of the optometry apparatus is controlled. It may be configured to prohibit this.

Such an operation control means suppresses switching to a control operation based on the other operation signal while a control operation based on one operation signal is being executed, and allows the examination of the subject's eye to be carried out efficiently and safely. be able to.

Note that the operator who operates the optometry device may be notified whether the optometry device is in a state where the operation can be performed or whether the operation of the optometry device is prohibited. For example, the notification may be made by at least one of displaying on a display means, audio guide, and the like.

<Operator information acquisition means>
In this embodiment, the optometry system includes information acquisition means (for example, the control unit 303). The information acquisition means acquires operator information that is information about an operator who operates the optometric apparatus.

<Photography Department>
The photographing unit 200 is used to photograph the examination room 10. The photographing unit 200 may photograph the examination room 10 as a moving image, or may photograph the examination room 10 as still images at regular intervals. The photographing unit 200 may be placed at any position in the examination room 10 as long as it is possible to photograph the examination room 10 including the subject P and the optometric apparatus 100. That is, the imaging unit 200 may be arranged in the examination room 10 with an angle of view that includes at least the subject P and the optometric apparatus 100. In this embodiment, the imaging unit 200 is arranged at a corner and above the examination room 10.

Note that in this embodiment, a night vision camera (for example, a high-sensitivity camera, an infrared camera, etc.) that can be used even under night vision may be used as the imaging unit 200. This makes it possible to photograph the examination room 10 under night vision.

Further, in this embodiment, the photographing unit 200 may include a microphone and a speaker (not shown). For example, the voice of the subject P picked up by the microphone of the imaging unit 200 may be emitted from a speaker (not shown) of the remote control unit 300 and transmitted to the examiner D. Furthermore, for example, the voice of the examiner D picked up by a microphone (not shown) of the remote control section 300 may be emitted from a speaker (not shown) of the imaging section 200 and transmitted to the subject P.

<Remote control unit>
The remote control unit 300 is in a state in which it is possible to guide the subject P to the optometry apparatus 100 and to perform an examination of the eye E to be examined by the optometry apparatus 100 (in other words, a state in which it is possible to start the examination of the eye E to be examined). It is used to For example, in this embodiment, when the subject P places his or her chin on the chinrest 104b, the eye E can be examined by the optometry apparatus 100. The remote control unit 300 includes a monitor 301, a control unit (mouse) 302, a control unit 303, and the like.

FIG. 4 is an example of the screen of the monitor 301 in the remote control unit 300. An operation screen 500 for operating the optometry apparatus 100 is displayed on the monitor 301 . For example, in FIG. 4, the aforementioned anterior segment image 501 and a tomographic image 502 generated from OCT data are displayed as the operation screen 500. Furthermore, a photographed image 600 photographed by the photographing unit 200 is displayed on the monitor 301. The photographed image 600 shows the subject P, the OCT apparatus 100, and the like.

Note that in this embodiment, an example is given in which one monitor 301 is used, but a plurality of monitors may be used. As an example, two monitors may be used as a first monitor and a second monitor, and either the operation screen 500 or the photographed image 600 may be displayed on the first monitor, and the other may be displayed on the second monitor. In other words, the screen of the monitor 301 may be expanded by using multiple monitors.

Further, the monitor 301 may be a touch panel, and the monitor 301 may also serve as the operation unit 302. In this case, an operation signal corresponding to the operation by examiner D is input from the monitor 301 and output to the control unit 303.

An operation signal corresponding to an operation by the examiner D is input from the operation unit 302 . An operation signal input from the operation unit 302 is output to the control unit 303. Further, this operation signal is output from the control unit 303 to the control unit 107 of the OCT apparatus 100 via the shared server 400.

The control unit 303 includes a general CPU, RAM, ROM, etc., and controls the remote control unit 300 to control the display on the monitor 301. A monitor 301, an operation unit 302, and the like are electrically connected to the control unit 303.

In this embodiment, the control unit 303 controls the monitor 301 to simultaneously display the operation screen 500 and the photographed image 600 on the screen of the monitor 301. Note that displaying the operation screen 500 and the photographed image 600 at the same time is not necessarily limited to displaying the operation screen 500 and the photographed image 600 at the same timing. It is sufficient that both the operation screen 500 and the photographed image 600 are displayed on the screen of the monitor 301, and the operation screen 500 and the photographed image 600 may be displayed at different timings.

As an example, the control unit 303 may, based on each of an operation signal (first operation signal) for displaying the operation screen 500 and an operation signal (second operation signal) for displaying the photographed image 600, The operation screen 500 and the photographed image 600 may be displayed on the screen of the monitor 301. For example, based on these operation signals, either the operation screen 500 or the photographed image 600 may be displayed on the screen of the monitor 301 first, and the other may be displayed on the screen of the monitor 301 later. That is, the operation screen 500 and the photographed image 600 may be displayed at different timings. Note that the first operation signal and the second operation signal may be used in common, and the operation screen 500 and the photographed image 600 may be displayed at the same timing based on the output of the first operation signal (second operation signal). .

<Action assignment>
The optometry system 1 can allocate the input of operation signals for the OCT apparatus 100 to perform various operations to the operation unit 101 included in the OCT apparatus 100 and the operation unit 302 included in the remote control unit 300. can. For example, the operation of the OCT device 100 may be an operation for aligning the OCT device 100 and the eye E to be examined, setting for acquiring OCT data, starting the examination, adjusting the height of the chin rest 104b, etc. (Details will be explained later).

The allocation of operations in the OCT apparatus 100 may be set in advance for each operation of the OCT apparatus 100. It may be possible to set it arbitrarily by the examiner D. The settings may be automatically changed according to the operator information of the operator (for example, examiner D) who operates the OCT apparatus 100.

<Display of operator information>
The optometry system 1 can acquire operator information of an operator (for example, examiner D) who operates the OCT apparatus 100 and can present the operator information to the subject P. For example, the operator information may be acquired by inputting a user ID, reading a one-dimensional code (for example, a barcode) or a two-dimensional code (for example, a QR code (registered trademark)), or the like.

<Operation>
Using the optometry system having the above configuration, the examiner D in the operation room 20 guides the patient P who has entered the examination room 10 to the OCT device 100 and examines the eye E using the OCT device 100. Explain the action to perform.

<Power on the OCT device>
First, the examiner D turns on the power of the OCT apparatus 100. For example, examiner D operates the operation unit 302 to select a power switch (not shown) for turning on the power of the OCT apparatus 100 displayed on the monitor 301. The control unit 303 of the remote control unit 300 transmits the operation signal input from the power switch to the control unit 107 of the OCT apparatus 100 via the shared server 400. The control unit 107 of the OCT apparatus 100 activates the OCT apparatus 100 in response to the received operation signal. When the OCT apparatus 100 is activated, a completion signal indicating that the OCT apparatus 100 has been activated is issued.

<Displaying the operation screen on the remote control unit>
The control unit 107 of the OCT apparatus 100 transmits an operation screen 500 for operating the OCT apparatus 100 to the control unit 303 of the remote operation unit 300 in response to the completion signal. The control unit 303 displays the received operation screen 500 on the monitor 301.

<Assignment of OCT device operations>
The examiner D inputs operation signals for the OCT apparatus 100 to perform various operations in advance to the operation unit 302 operated by the examiner D and the operation unit 101 operated by the subject P. assign. Examiner D operates an operation screen 500 displayed on the monitor 301 to call an operation setting screen 503 for setting operation assignments of the OCT apparatus 100.

FIG. 5 is an example of the operation setting screen 503. The operation setting screen 503 includes a list 503a of operations in the OCT apparatus 100, a box 503b for selecting an operation to be assigned to the operation section 302 operated by the examiner D (indicated as the first operation section in FIG. 5), and a box 503b for selecting an operation to be assigned to the operation section 302 operated by the examiner A box 503c for selecting an action to be assigned to the operation unit 101 (indicated as the second operation unit in FIG. 5) operated by P is displayed.

Examiner D inputs operation signals from the operation unit 302, inputs operation signals from the operation unit 101, or inputs operation signals from the operation unit 302 and the operation unit 101 for various operations of the OCT apparatus 100. or change. That is, it is selected whether the examiner D, the examinee P, or the examiner D and the examinee P instruct the OCT apparatus 100 to perform various operations.

For example, the allocation will be explained by taking as an example an alignment operation for aligning the OCT apparatus 100 and the eye E to be examined.

In this embodiment, the examiner D is in the operation room 20 and the patient P is in the examination room 10, so the examiner D can interact with the operation screen 500 (for example, the anterior segment image 501) displayed on the monitor 301. By observing the photographed image 500, the eye E of the subject P is indirectly confirmed. In alignment between the OCT apparatus 100 and the eye E to be examined, it is necessary to move the measurement unit 103 in the vertical direction, left-right direction, and front-back direction with respect to the eye E to be examined. However, since the examiner D is looking at the eye E to be examined through the monitor 301, it is difficult to grasp the positional relationship between the eye E to be examined and the measurement unit 103. In particular, it is difficult to grasp the positional relationship between the eye E to be examined and the measurement unit 103 in the front-back direction (in other words, the sense of distance between the eye E to be examined and the measurement unit 103).

Therefore, the examiner D assigns the input of the operation signal for executing the alignment operation to the operation unit 101 operated by the examinee P, so that the examiner D can set the input so that the examinee P can instruct the execution of the alignment operation. You may. On the operation setting screen 503, examiner D selects box B1b corresponding to alignment operation from among boxes 503c for selecting an operation to be assigned to operation section 101 (second operation section).

The control unit 303 of the remote control unit 300 transmits a selection signal generated when box B1b is selected to the control unit 107 of the OCT apparatus 100 via the shared server 400. The control unit 107 of the OCT apparatus 100 allows input of an operation signal for executing an alignment operation to the operation unit 101 according to the received selection signal.

For example, in this way, the alignment operation for aligning the OCT apparatus 100 and the eye E to be examined may be assigned only to the operation unit 101. That is, the setting may be such that only the subject P can instruct execution of the alignment operation.

In this embodiment, the examiner D does not select the box B1a corresponding to the alignment operation among the boxes 503b for selecting an operation to be assigned to the operation section 302 (first operation section). In this case, since no selection signal is generated due to the selection of box B1a, the control unit 303 of the remote control unit 300 prohibits the operation unit 302 from inputting an operation signal for executing the alignment operation.

Of course, the examiner D is not limited to the alignment operation, but also the operation to perform settings for obtaining OCT data using the OCT apparatus 100 (setting operation), and the operation to start an examination using the OCT apparatus 100 (examination start operation). ), an operation for photographing the eye to be examined (photographing operation), an operation for adjusting the height of the chin rest 104b (chin rest adjustment operation), etc. are assigned to at least one of the operation unit 302 and the operation unit 101. You may set each of them as follows.

For example, in this embodiment, the setting operation and the test start operation are assigned only to the operation unit 302. That is, settings are made such that only examiner D can instruct execution of the setting operation and test start operation. Further, for example, in this embodiment, the chin rest adjustment operation is assigned to the operating section 302 and the operating section 101. That is, the settings are made so that the examiner D and the subject P can instruct execution of the chin rest adjustment operation.

<Turn on the power to the photography department>
After the examiner D finishes assigning the operations of the OCT apparatus 100, he turns on the power of the imaging unit 200. For example, examiner D operates the operation unit 302 to select a power switch (not shown) for turning on the power of the imaging unit 200 displayed on the monitor 301. The control unit 303 of the remote control unit 300 transmits the operation signal input from the power switch to the control unit 202 of the photographing unit 200 via the shared server 400. The control unit 202 of the imaging unit 200 activates the imaging unit 200 in response to the received operation signal. When the photographing section 200 starts, a completion signal indicating that the photographing section 200 has started is issued.

<Displaying captured images on the remote control unit>
The control unit 202 of the imaging unit 200 starts imaging the examination room 10 in response to the completion signal. The control section 202 of the photographing section 200 transmits photographed images 600 sequentially photographed by the detector 201 to the control section 303 of the remote control section 300 . The control unit 303 displays the received captured image 600 on the monitor 301.

For example, in this way, the operation screen 500 of the OCT apparatus 100 and the captured image 600 of the examination room 10 captured by the imaging unit 200 are displayed simultaneously on the monitor 301 observed by the examiner D. That is, the operation screen 500 and the photographed image 600 are displayed on the same screen on the monitor 301.

<Guidance of subject>
Examiner D observes the captured image 500 displayed on the monitor 301 and, when confirming that the patient P has entered the examination room 10, instructs the patient P to sit in front of the OCT apparatus 100. put out. Furthermore, when the examiner D confirms that the examinee P is seated in front of the OCT apparatus 100, the examiner D instructs the examinee P to place his or her chin on the chin rest 104b of the OCT apparatus 100.

A detector 105 is provided on the jaw rest 104b of the OCT apparatus 100. When detecting an external load, the detector 105 detects that the chin of the subject P is placed on the chin rest 104b. Further, the detector 105 converts this load into an electrical signal and outputs it to the control unit 107.

When the electric signal is input, the control unit 107 determines that the chin of the subject P is placed on the chin rest 104b, and that the subject's eye E can be examined. Further, the control unit 107 transmits a determination result indicating that the test eye E is ready for examination to the control unit 303 of the remote control unit 300 via the shared server 400. The control unit 303 of the remote control unit 300 may display a message M1 (see FIG. 6) on the monitor 301 based on the detection result of the detector 105. For example, in this embodiment, when it is detected that the eye E to be examined is ready for examination, a message is displayed notifying that the examiner D can start the next operation.

The examiner D guides the examinee P to the OCT apparatus 100, and after confirming that the examinee's eye is ready for examination, selects a power switch (not shown) displayed on the monitor 301 and returns to the examination room. Turn off the 10 lights. In this embodiment, since the photographing unit 200 is a night vision camera, even if the electricity in the examination room 10 is turned off, the photographed image 600 is taken under night vision, and the monitor 301 displays the images of the examination room 10 and the subject. You can observe the situation.

<Alignment of the eye to be examined>
The examiner D observes the photographed image 600 displayed on the monitor 301 and instructs the subject P to gaze at a monitor (not shown) provided in the measuring section 103. For example, the content of the instruction given by the examiner D to the subject P may be displayed as a message on a monitor (not shown). Further, for example, a fixation target for causing the subject's eye to fixate may be displayed on a monitor (not shown). For example, after such a message is displayed for a certain period of time, it may be possible to automatically switch to the fixation target. Of course, the message and the fixation target may be displayed simultaneously.

Furthermore, the examiner D observes the photographed image 600 displayed on the monitor 301 and instructs the subject P to start alignment. For example, the examiner D may instruct the subject P to operate an alignment start switch (not shown) provided on the operation unit 101 of the OCT apparatus 100. When the subject P operates the alignment start switch, the control unit 107 controls the anterior segment imaging optical system in response to a start signal from the alignment start switch, and captures the anterior segment image 501 of the subject's eye E. At the same time, an alignment index image K1 is projected onto the cornea of the eye E to be examined. Further, the control unit 107 uses the alignment index image K1 to detect a positional deviation of the corneal apex position (approximately the corneal apex position) of the eye E to be examined with respect to the measurement optical axis of the measurement unit 103, and performs automatic alignment.

FIG. 6 is an example of the screen of the monitor 301. The control unit 107 of the OCT apparatus 100 transmits the anterior segment image 501 to the control unit 303 of the remote control unit 300 via the shared server 400, and the control unit 303 causes the anterior segment image 501 to be displayed on the monitor 301. That is, the anterior segment image 501 of the eye E to be examined is displayed on the monitor 301 as the operation screen 500 of the OCT apparatus 100. Examiner D can check the alignment state of OCT device 100 and subject's eye E by observing anterior segment image 501 displayed on monitor 301.

Note that in this embodiment, the alignment operation in the OCT apparatus 100 is not assigned to the operation unit 302 operated by the examiner D. Therefore, even if the examiner D operates the operation unit 302, an operation signal for executing the alignment operation is not input. Note that at this time, a message may be displayed on the monitor 301 observed by the examiner D indicating that the operation unit 302 cannot be operated.

Of course, in addition to the operation section 101 operated by the examinee P, the alignment operation is also assigned to the operation section 302 operated by the examiner D, so that when the alignment by the examinee P is not successful, etc. may also be able to perform alignment.

<Adjustment of the chin rest>
In the automatic alignment described above, if the eye E to be examined is shifted to a position higher or lower than the vertical movement limit of the measurement unit 103, the movement of the measurement unit 103 will stop midway, and the alignment may not be successful. There may be no. Therefore, the examiner D observes the anterior segment image 501 and adjusts the height of the chin rest 104b as necessary.

The examiner D may instruct the subject P to adjust the height of the chin rest 104b by operating a chin rest adjustment switch (not shown) provided on the operation unit 101. For example, in FIG. 6, the eye E to be examined is in a high position relative to the measurement unit 103, so an instruction may be issued to lower the chin rest 104b. When the subject P operates the chin rest adjustment switch, the control unit 107 moves the chin rest 104b downward in accordance with the adjustment signal from the chin rest adjustment switch. In addition, examiner D observes the anterior segment image 501 displayed on the monitor 301 and confirms that the position of the subject's eye E reflected in the anterior segment image 501 has lowered. You may be instructed to do this again.

Of course, examiner D may adjust the height of the chin rest 104b by operating the operating unit 302 of the remote control unit 300 and selecting a chin rest adjustment switch (not shown) displayed on the monitor 301. . The control unit 303 of the remote control unit 300 transmits the operation signal input from the chin rest adjustment switch to the control unit 107 of the OCT apparatus 100 via the shared server 400. The control unit 107 of the OCT apparatus 100 moves the chin rest 104b in the vertical direction according to the received operation signal.

<Setting inspection conditions>
When the alignment of the OCT apparatus 100 and the eye E to be examined is completed, the examiner D sets conditions for starting the examination of the eye E to be examined. Examiner D operates the operation screen 500 displayed on the monitor 301 to call up a setting screen for setting examination conditions for the OCT apparatus 100. The examiner D also operates the setting screen to set conditions such as the scanning position of the measurement light, the scanning pattern of the measurement light (for example, line scan, raster scan, circle scan, radial scan, etc.).

The control unit 303 of the remote control unit 300 transmits a selection signal generated by selecting each condition to the control unit 107 of the OCT apparatus 100 via the shared server 400. The control unit 107 of the OCT apparatus 100 sets inspection conditions for the OCT apparatus 100 according to the received selection signal.

In this embodiment, an operation signal (first operation signal) issued when examiner D operates operation unit 302 and an operation signal (second operation signal) issued when examinee P operates operation unit 101. When the operation of the OCT apparatus 100 is being executed by one of the operation signals, the execution of the operation of the OCT apparatus 100 by the other operation signal is prohibited. Therefore, when the examiner D is performing the setting operation, the subject P is prohibited from performing the alignment operation or the chinrest adjustment operation. For example, when examiner D is operating the operation unit 302, even if the patient P operates the operation unit 101, the input of operation signals from the operation unit 101 is disabled. Good too. For example, the fact that the input of the operation signal by the operation unit 101 is disabled may be announced as a sound from a speaker (not shown).

<Start of inspection>
After setting the test conditions for the OCT apparatus 100, the examiner D starts testing the eye E to be examined. For example, examiner D operates the operation unit 302 to select an examination start switch (not shown) for starting the examination of the OCT apparatus 100 displayed on the monitor 301. The control unit 303 of the remote control unit 300 transmits the start signal input from the test start switch to the control unit 107 of the OCT apparatus 100 via the shared server 400. The control unit 107 of the OCT apparatus 100 starts an examination by the OCT apparatus 100 in response to the received start signal. Note that the control unit 107 may display a message indicating that imaging is to be started on a monitor (not shown) of the measurement unit 103 in response to the received start signal.

For example, in response to the start signal, the control unit 107 of the OCT apparatus 100 performs optimization control (for example, adjusting the optical path length) for observing the fundus of the eye E desired by the examiner D with high sensitivity and high resolution. , focus adjustment, polarization state adjustment, etc.) and acquisition of OCT data. The control unit 107 of the OCT device 100 may generate a tomographic image of the eye E from the acquired OCT data, and transmit this tomographic image to the control unit 303 of the remote control unit 300 via the shared server 400. . Note that at this time, the control unit 107 may transmit the tomographic image to the control unit 303 in a state in which the resolution of the tomographic image is lowered or in a state in which the tomographic image is compressed. Upon receiving the tomographic image 502, the control unit 303 may display the tomographic image 502 on the monitor 301. That is, a tomographic image 502 of the eye E to be examined may be displayed on the monitor 301 as the operation screen 500 of the OCT apparatus 100. By observing the tomographic image 502 displayed on the monitor 301, the examiner D can easily examine the eye E even if he or she is far from the patient P.

Note that, for example, when imaging by the OCT apparatus 100 is completed, the unillustrated monitor of the measurement unit 103 may be switched from the fixation target to a message indicating that imaging has ended.

<Display of examiner information>
Note that the optometry system 1 in this embodiment may present information on the operator who operates the OCT device 100 (for example, information related to the examiner D, etc.) to the subject P. For example, the operator information may be at least one of the operator's name, affiliation, etc., and is stored in the memory 402 of the shared server 400 in association with the user ID that examiner D has individually. may have been done.

FIG. 7 is an example of operator information 700 presented to the subject P. For example, examiner D inputs a user ID when using remote control unit 300. The control unit 303 of the remote control unit 300 transmits the user ID to the control unit 401 of the shared server 400. Upon receiving the user ID, the control unit 401 reads the operator information corresponding to the user ID from the memory 402 and transmits the operator information to the control unit 107 of the OCT apparatus 100 . The control unit 107 may present the operator information to the subject P by displaying the operator information on a monitor. Note that the operator information 700 may be displayed on a monitor provided separately from the OCT device 100, or may be displayed on a monitor provided within the measurement unit 103 of the OCT device 100.

As explained above, for example, the optometry system in this embodiment includes an optometry device that tests the eye of a subject, a photographing means that takes pictures of the examination room including the subject and the optometry device, and an optometrist that operates the optometry device. a display means for displaying an operation screen and a photographed image taken by the photographing means; and a display control means for controlling the display of the display means to display the operation screen and the photographed image on the display means, The apparatus includes remote control means that can guide a subject to an examination position by observing a photographed image displayed on the means. With this configuration of the optometry system, even if the examiner and patient are not in the same space, the examiner can issue appropriate instructions while observing the patient, allowing for efficient eye examination. You can proceed well.

Further, for example, the optometry system according to the present embodiment displays an operation screen for operating the optometrist and a photographed image taken by the photographing means on the same screen of the display means. This allows the examiner to monitor a series of movements of the examinee (for example, after the examinee enters the examination room and then examine the examinee's eyes using the optometry device) without being in the same space as the examinee. While operating the optometry device, it is possible to observe the patient's behavior (for example, the patient's behavior while the patient's eye is being examined). Therefore, the eye to be examined can be tested efficiently.

Further, for example, in the optometry system according to the present embodiment, the photographing means includes a night vision camera that photographs the examination room under night vision, so that it is possible to photograph the examination room under night vision. In the field of ophthalmology, a dark room is often created when examining the eye to be examined in order to reduce the influence of changes in ambient light such as lighting equipment in the examination room on examination accuracy. By enabling imaging under night vision, it is possible to observe the subject's condition even in a dark room, and the subject's eye can be examined with high precision.

Further, for example, in the optometry system according to the present embodiment, the optometry apparatus includes a determination unit that determines whether or not the eye to be examined is in a state where it can be examined, and a first determination unit that outputs determination information based on the determination result of the determination unit. and an output means. For example, by outputting the determination information, the examiner can easily understand whether the test subject is ready for examination.

For example, in the optometry system of the present embodiment, the optometry device includes a determining means for determining whether or not the eye to be examined is in a state in which an examination is possible, and based on the determination result of the determining means, the optometry device or the remote control At least one of the means includes second output means for outputting an instruction signal for instructing the next operation. Thereby, the examiner can efficiently proceed with the examination of the subject's eye.

Further, for example, in this embodiment, an imaging means is arranged above the examination room. This makes it easier for the imaging means to photograph the entire examination room, and it also becomes easier for the examiner to understand the state of the examination room using the image taken by the imaging means. Note that at this time, by arranging the photographing means above and at the corner of the examination room, it becomes easy to photograph the entire examination room even if a simple camera is used.

For example, the optometry system in this embodiment includes an optometry device that examines the eye to be examined, a first operation unit that is provided in the housing of the optometry device or near the optometry device and that operates the optometry device, and a first operation unit that is separated from the optometry device. a second operating section provided at a location for operating the optometry device; a first setting means for assigning a first operation in the optometry device to a first operation signal inputted from the first operating section; A second setting means is provided for assigning a second operation in the optometry apparatus to an input second operation signal. As a result, appropriate actions are assigned according to the location and skill of the operator operating the optometry device (i.e. examiner, patient, assistant, etc.), the content of the action when examining the subject's eye, etc. be able to. The examiner can easily examine the eye to be examined without being present in the space where the optometrist is placed.

Further, for example, the optometry apparatus according to the present embodiment includes a fundus photographing means for photographing the fundus of the eye to be examined, and at least one of the first setting means and the second setting means is configured to respond to the operation signal by the fundus photographing means. Assign an action to start. For example, in this embodiment, the imaging start operation is assigned to the operation unit operated by the examiner, and the imaging start operation is not assigned to the operation unit operated by the subject. Therefore, even if the subject issues an operation signal to start imaging, malfunctions of the optometric apparatus are suppressed.

Further, for example, the optometry apparatus in this embodiment includes an alignment means for aligning the eye to be examined and the optometry apparatus, and at least one of the first setting means and the second setting means receives the operation signal from the alignment means. Assign an operation to perform alignment. For example, in this embodiment, the alignment operation is not assigned to the operation unit operated by the examiner, but is assigned to the operation unit operated by the subject. Alignment can be performed safely by having the examinee who is able to grasp the sense of distance between the examinee's eye and the apparatus perform the alignment operation.

Further, for example, the optometry system in this embodiment includes an acquisition unit that acquires operator information that operates the optometry device, a display unit that can display the operator information, and a display control unit that causes the display unit to display the operator information. and. As a result, even if the examiner and the examinee are not in the same space, the examinee can know the examiner's information and take the examination with peace of mind.

<Transformation example>
In addition, in this example, although the structure which guides the subject P by the voice of the examiner D was given as an example and demonstrated, it is not limited to this. For example, a lamp may be provided on the OCT apparatus 100, a passageway to the OCT apparatus 100, a chair, etc., and the subject P may be guided by lighting or blinking the lamp. The examiner D may check whether the subject P is heading toward the OCT apparatus 100 while viewing the photographed image 600 displayed on the monitor 301 of the remote control unit 300, and may issue appropriate instructions.

Note that in this embodiment, a configuration in which the photographing unit 200 and the remote control unit 300 are provided with a microphone and a speaker (not shown) has been described as an example, but the present invention is not limited to this. In this embodiment, it is sufficient that the voices of examiner D and examinee P can be transmitted to each other. As an example, a configuration may be adopted in which a microphone and a speaker are provided separately from the OCT device 100, the imaging unit 200, and the remote control unit 300. Further, as an example, a microphone and a speaker may be provided in the OCT apparatus 100.

In this embodiment, a configuration is exemplified in which a photographed image 600 of the examination room 10 and an operation screen 500 for operating the OCT apparatus 100 are simultaneously displayed on the monitor 301 of the remote control unit 300. Although described, the invention is not limited to this. For example, the captured image 600 and the operation screen 500 may be switched and displayed on the screen of the monitor 301. In this case, the control unit 107 of the OCT apparatus 100 may switch between the captured image 600 and the operation screen 500 based on a switching signal for switching between the captured image 600 and the operation screen 500. For example, the switching signal may be issued by the examiner D operating a switch for switching between the captured image 600 and the operation screen 500. Further, for example, the switching signal may be issued by starting the OCT apparatus 100 or the imaging unit 200, completing alignment, outputting an electrical signal by the detector 105, or the like.

For example, as described above, the optometry system according to the present embodiment includes a signal acquisition means for acquiring a switching signal for switching between an operation screen for operating an optometry apparatus and a photographed image photographed by a photographing means, The display control means switches and displays an operation screen for operating the optometry apparatus and a photographed image photographed by the photographing means on the screen of the display means based on the switching signal. The examiner can easily give instructions to the subject and examine the subject's eye while observing the screen where the operation screen and the captured image are switched manually or automatically.

In this embodiment, the remote control section 300 has been described as having a monitor 301 and an operation section 302, but the present invention is not limited to this. For example, the remote control unit 300 may have a monitor 301 but may not include the operation unit 302. In this case, the OCT apparatus 100 may be provided with a configuration for fully automatically controlling the process from the start of alignment to the end of the examination for the eye E to be examined. Examiner D guides the patient P to the OCT device 100 while observing the captured image 600 displayed on the monitor 301, and the OCT device 100 indicates that the patient P is ready for examination. Fully automatic control may be performed based on the determination.

In this embodiment, the examiner D is in the operation room 20 and the examinee P is in the examination room 10, and the examiner D gives instructions to the examinee P while observing the photographed image 600. Although the description has been given above, the invention is not limited thereto. For example, there is an examiner D in the operation room 20, a patient P and an assistant who assists the patient P in the examination room 10, and the examiner D gives instructions to the assistant while observing the captured image 600. Good too. In this case, the examiner D may instruct the assistant to guide the examinee P, turn off and on the lights in the examination room 10, start alignment of the examinee's eyes, adjust the chin rest, etc. Furthermore, in this case, the examiner D may change the assignment of various operations in the OCT apparatus 100. For example, as the operation unit operated by the assistant, the operation unit 101 provided in the OCT apparatus 100 may be used, or the monitor 106 may be used.

In addition, in this embodiment, a configuration has been described as an example in which all operations in the alignment operation are assigned to the operation unit 302 operated by examiner D and the operation unit 101 operated by examinee P. but is not limited to this. A configuration may be adopted in which at least part of the alignment operation is assigned to the operation unit 302 and the operation unit 101. More specifically, a configuration may be adopted in which a vertical motion for moving the measuring section 103 in the vertical direction, a left-right motion for moving the measuring section 103 in the left-right direction, and a back-and-forth motion for moving the measuring section 103 in the front-back direction are assigned to each. Of course, the operations assigned to the operation unit 302 and the operation unit 101 may overlap.

As an example, the operation unit 302 operated by the examiner D is assigned the vertical and horizontal movements in the alignment operation, and the operation unit 101 operated by the subject P (or assistant) is assigned the back and forth movements in the alignment operation. Good too. As an example, the operation unit 302 operated by the examiner D is assigned the vertical and horizontal movements in the alignment operation, and the operation unit 101 operated by the examinee P (or assistant) is assigned all the operations in the alignment operation. (that is, up and down movement, left and right movement, and back and forth movement) may be assigned.

Note that in this embodiment, various operations in the OCT apparatus 100 are not assigned to the operation unit 101 and the operation unit 302, so that settings are made to prohibit input of operation signals for executing various operations. Although the explanation has been given above, the invention is not limited thereto. For example, a configuration may be adopted in which prohibition settings are made on the operation unit 101 and the operation unit 302 to prohibit execution of various operations in the OCT apparatus 100.

When such a prohibition setting is made for the operation unit 101, for example, the input of an operation signal may be prohibited so that the operation signal from the operation unit 101 is not transmitted to the control unit 107. Further, as an example, the operation signal may be disabled in the communication path between the operation unit 101 and the control unit 107 so that the control unit 107 does not receive the operation signal from the operation unit 101. Further, as an example, even if the control unit 107 receives an operation signal from the operation unit 101, the control unit 107 may be controlled not to perform an operation based on the operation signal.

When such a prohibition setting is made for the operation unit 302, for example, input of an operation signal may be prohibited so that the operation signal from the operation unit 302 is not transmitted to the control unit 303. For example, the communication path between the operation unit 302 and the shared server 400 or the communication between the shared server 400 and the operation unit 101 may be changed so that the control unit 107 does not receive the operation signal from the operation unit 302. The operation signal may be invalidated in any one of the routes. Further, as an example, even if the control unit 107 receives an operation signal from the operation unit 302, the control unit 107 may be controlled not to perform an operation based on the operation signal.

For example, in the optometry system according to the present embodiment, when an operation of the optometry apparatus is performed based on one of the first operation signal and the second operation signal, the optometry system according to the present embodiment operates according to the other operation signal. An operation control means for prohibiting the operation of the optometry device is provided. This prevents switching to a control operation based on the other operation signal while a control operation based on one operation signal is being executed, and allows the eye to be examined to be tested efficiently and safely.

In addition, in this embodiment, with respect to the operating section 302 operated by the examiner D and the operating section 101 operated by the subject P, while one operating section is used, the operation section 302 operated by the examiner D and the operating section 101 operated by the subject P are Although the description has been given using an example of a configuration that prohibits execution of an operation, the present invention is not limited to this. As an example, depending on the operation to be performed when testing the subject's eye E, priority may be given to execution of the operation by the operation unit 302. In other words, even when a predetermined operation is being executed by the operation unit 101, operating the operation unit 302 prohibits the operation unit 101 from performing the operation, and prevents the operation unit 302 from performing the predetermined operation. It may be configured such that it is permitted. Of course, depending on the operation to be performed when examining the eye E, execution of the operation by the operation unit 101 may be given priority.

In this embodiment, the configuration in which the imaging unit 200 is provided in the examination room 10 has been described as an example, but the present invention is not limited to this. For example, the imaging unit 200 may be provided in the OCT apparatus 100. As an example, the imaging unit 200 may be stacked on top of the OCT apparatus 100. Further, as an example, the imaging unit 200 may be arranged in parallel on the side of the OCT apparatus 100. In such a case, the imaging unit 200 may photograph the examination room 10 including the subject.
