As an example, the eye to be inspected may be measured using an optometry system. Further, as an example, the eye to be inspected may be imaged using an optometry system.

Such an optometry system may be an optometry system for measuring optical characteristics of the subject's eye. For example, as the optical characteristics of the eye to be inspected, the eye refractive power (for example, spherical power, cylindrical power, astigmatic axis angle, etc.), eye axial length, corneal shape, etc. may be subjectively measured. Further, for example, as the optical characteristics of the eye to be inspected, the eye refractive power of the eye to be inspected, the contrast sensitivity, the binocular vision function (for example, the amount of oblique position, the stereoscopic vision function, etc.) may be objectively measured. .. Further, such an optometry system may be an optometry system for measuring the visual field of the subject's eye by obtaining a response by the subject's visual recognition.

Further, such an optometry system may be an optometry system for photographing the anterior segment or fundus of the subject's eye. For example, the anterior segment image data of the subject's eye, the corneal shape, and the like may be acquired by photographing the anterior segment of the subject's eye. Moreover, the fundus front image data, tomographic image data, and the like of the subject's eye may be acquired by photographing the fundus of the subject's eye.

<Photographing in the examination room and examination using an optometry device>

The communication means may use at least one of wired communication and wireless communication to communicate with other means. For example, in the case of wired communication, an optical fiber, a wired LAN, etc. may be used. For example, in the case of wireless communication, Wi-Fi (registered trademark), Bluetooth (registered trademark), or the like may be used. The communication unit may have a receiving unit and a transmitting unit. The receiving means and the transmitting means may be combined, or may be provided separately.

The optometry system according to the present embodiment may be configured such that the optometry apparatus directly communicates with other means via the communication means. Further, the optometry system according to the present embodiment may include a shared server (for example, the shared server 400), and the optometry apparatus may indirectly communicate with other means from the communication means via the shared server. .. That is, the optometry apparatus and other means may be connected via the shared server.

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

As the detecting unit, an image capturing unit (for example, a camera including an image sensor) capable of detecting contact between the optometry apparatus and the subject may be used. In this case, the contact between the optometry apparatus and the subject may be determined by analyzing the image captured by the image capturing unit.

Further, as the detection means, a sensor (for example, at least one of an optical sensor, a pressure sensor, a load sensor, etc.) capable of detecting contact between the optometry apparatus and the subject may be used. The detection means may detect that the optometry apparatus and the subject are in contact with each other, based on a detection signal generated when the optometry apparatus and the subject are in contact with each other. 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 electric resistance value and output the electric resistance value. The contact between the optometry apparatus and the subject may be detected based on whether or not the potential resistance value is output (in other words, whether or not the detection signal is output). For example, the detection unit may detect that the optometry apparatus and the subject are in contact with each other when the potential resistance value is output.

When the optometry apparatus has a forehead support for abutting the forehead of the subject, the detection means is provided on the forehead support and detects whether the forehead of the subject is contacted with the forehead support. Good. The detection means may detect that the forehead of the subject has come into contact with the forehead support when the load is detected from the forehead support. 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 to detect whether or not the chin of the subject is placed on the chin rest. You may. The detection means may detect that the jaw of the subject has contacted the chin rest when the 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.

In addition, in the present embodiment, the detection unit does not necessarily have to be configured to detect the contact between the optometry apparatus and the subject. The detection means may be configured to detect the positional relationship between the optometry apparatus and the subject. As an example, the detection means may be a distance sensor. Further, as an example, the detection unit may be a photographing unit. In this case, the photographing means may photograph the optometry device and the subject, and detect whether the optometry device and the subject are at a predetermined distance. Further, in this case, the photographing means may photograph the face of the subject to detect the face of the subject.

<Judgment means>
In the present embodiment, the optometry apparatus includes a determination unit (for example, the control unit 107). The determination means determines whether or not the eye to be inspected can be inspected. For example, the state in which the examination of the eye to be inspected is a state in which the examination of the eye to be inspected can be started. As an example, the face of the subject may be fixed to the optometry device using a forehead pad. Further, as an example, the face of the subject may be fixed using a chin rest. Further, as an example, the optometry apparatus and the subject may be in a predetermined positional relationship.

The determination unit may determine whether or not the eye to be inspected is in a state in which it can be inspected based on the detection result of the detection unit. For example, the determination means may determine that the state in which the examination of the eye to be inspected can be started when the detection means detects contact between the eye examination apparatus and the subject. More specifically, the determination unit may determine that the examination of the eye to be inspected can be started when the detection signal is emitted from the detection unit. In addition, for example, the determination unit may determine that the examination of the eye to be inspected is impossible when the detection unit does not detect contact between the eye examination apparatus and the subject. More specifically, it may be determined that the examination of the eye to be inspected cannot be started when the detection signal is not issued from the detection means.

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

The first output means may output, as the determination information, notification information for notifying the examiner of the determination result. In this case, the notification information is information indicating the determination result (that is, information indicating that it is possible or impossible to start the examination of the eye to be examined), information for guiding the examiner to the next action, and the like. May be

The first output means may output such notification information to the remote control means. For example, the first output unit may output the notification information as a message to the display unit included in the remote control unit. Further, for example, the first output means may output the notification information by generating a voice guide in the remote control means. Further, for example, the first output unit may output the notification information by lighting or blinking a lamp in the remote control unit.

Of course, the first output unit may output the notification information to a unit different from the remote control unit. For example, the first output unit 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 (for example, the control unit 107 and the control unit 303). The second output means outputs an instruction signal for instructing the next operation to at least one of the optometry apparatus and the remote operation means based on the determination result of the determination means. This allows the examiner to efficiently proceed with the examination of the eye to be examined.

The second output means may output an instruction signal to the optometry apparatus. In this case, the instruction signal may be an instruction signal for causing the optometry apparatus to start alignment, an instruction signal for causing the optometry apparatus to start an examination, or the like. 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 for displaying a screen for setting the optometry apparatus on the display means included in the remote control means.

In the present embodiment, the optometry apparatus may have a configuration in which the first output unit and the second output unit are combined, or may be provided separately. Further, in the present embodiment, the optometry apparatus may be configured to perform either one of the determination information output by the first output unit and the instruction signal output by the second output unit, or a configuration for performing both. Good.

In the present embodiment, the optometry apparatus may include alignment means. The alignment means aligns the eye to be inspected with the eye examination apparatus. The alignment unit may be configured to project an alignment index on the anterior segment of the eye to be inspected, and use the alignment index image to align the eye to be inspected with the optometry apparatus.

In this embodiment, the optometry apparatus may include a fundus imaging unit. The fundus photographing unit photographs the fundus of the subject's eye. For example, the fundus imaging unit may include at least one of an ophthalmic 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.

<Photographing means>
In the present embodiment, the optometry system includes a photographing unit (for example, the photographing unit 200). The imaging means images the examination room including the subject and the optometry device. For example, the examination room may be a bright room for examining the eye to be inspected. As an example, it may be a bright room for measuring the optical characteristics of the subject's eye. Further, for example, the examination room may be a dark room for examining the eye to be inspected. As an example, it may be a dark room for photographing the anterior segment or fundus of the subject's eye.

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 image capturing means may capture at regular time intervals (for example, at 5-second intervals).

The image capturing means may be capable of capturing an image of an image capturing room including the subject and the optometry device under clear vision. Further, the image capturing means may be capable of capturing an image of an image capturing room including the subject and the optometry device under night vision. In this case, a night-vision camera may be used as the photographing means. Examples of the night-vision camera include a high-sensitivity camera that amplifies sensitivity to light, an infrared camera that detects infrared rays emitted by an object, and the like.

Here, for example, in the field of ophthalmology, a dark room is often created when the eye to be inspected is inspected in order to reduce the influence on the inspection accuracy due to changes in ambient light such as lighting equipment in the inspection room. By enabling imaging under night vision as in the present embodiment, the state of the subject can be observed even in a dark room, and the subject's eye can be examined accurately.

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

The imaging means may be arranged at any position in the examination room as long as it can photograph the examination room including the subject and the optometry apparatus. For example, the imaging means may be arranged above the examination room. This makes it easier for the photographing means to photograph the entire examination room, and for the examiner to grasp the state of the examination room using the photographed image photographed by the photographing means.

The imaging means may be arranged in the central portion 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 photographing means may be arranged at a corner above the examination room. In this case, a directional camera, a camera having a swing function, or the like may be used as the photographing means. By arranging the photographing means above and in the corner of the examination room, the entire examination room can be photographed easily even if a simple camera is used.

<Remote control means>
In the present embodiment, the optometry system includes remote operation means (for example, remote operation unit 300). The remote control means may have an operation screen for operating the optometry apparatus and a display means (for example, the monitor 301) for displaying a captured image captured by the capturing means. Further, the remote operation means may have a display control means (for example, a control unit 303) that controls the display of the display means to display the operation screen and the captured image on the display means. That is, the remote operation means may have a display means and a display control means, and the subject may be guided to the examination position by observing the captured image displayed on the display means. With this configuration of the optometry system, even if the examiner and the examinee are not in the same space, the examiner can give an appropriate instruction while observing the examinee and efficiently examine the examinee's eye. I can proceed well.

The operation screen for operating the optometry apparatus may be a screen used for examining the eye to be inspected using the optometry apparatus. As an example, the operation screen may be a setting screen for making various settings in the optometry apparatus. When the optometry apparatus is an OCT apparatus, a screen for setting the scanning position, the scanning pattern, etc. of the measurement light for acquiring the OCT data may be displayed as the setting screen. Further, as an example, the operation screen may be a result screen showing the result of the examination using the optometry apparatus. When the optometry apparatus is an OCT apparatus, a tomographic image generated from OCT data may be displayed as the result screen. Further, as an example, the operation screen may be an eye image of the eye to be inspected. When the optometry apparatus is an OCT apparatus, an anterior segment image captured by the anterior segment imaging optical system included in the OCT apparatus may be displayed as the eye image.

The photographed image photographed by the photographing means may be an image photographed to guide the subject to the optometry apparatus. For example, it may be an image in which the entire examination room is photographed, and an image in which the optometry device and the subject can be observed. Further, for example, the image may be an image of at least a part of the examination room, and the image may allow observation of the optometry apparatus and the subject.

The examination position at which the subject is guided may be the position of the optometry apparatus. Further, the examination position where the subject is guided may be a position away from the optometry apparatus. As an example, the examination position in which the subject is guided may be the position of a chair used with the optometry apparatus, or the like.

<Display control means>
In the present embodiment, the display control means included in the remote control means controls the display of the display means to display the operation screen on the display means. Further, in the present 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 the photographed image photographed by the photographing 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 apparatus, and the like. Good.

The display control means may control the display of the display means so that the operation screen and the captured 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 captured image on the screen of the display means at the same timing. In this case, the display control means may display the operation screen and the captured image on the screen of the display means at different timings. For example, the display control means may be configured such that one of the operation screen and the captured image is displayed on the display means first, and the other is displayed on the display means later.

For example, by displaying the operation screen and the captured image on the same screen, the examiner does not need to be in the same space as the examinee to perform a series of actions by the examinee (for example, Operations from entering the examination room until the eye can be inspected using the optometry device, etc., and the state of the subject (for example, the state during the examination of the eye, etc.) ) Can be observed while operating the optometry apparatus, and the eye to be inspected can be efficiently examined.

In the present embodiment, the remote operation 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 captured image. The switching signal may be manually generated by the operation of the examiner. 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 determination unit determines that the eye to be inspected can be inspected. More specifically, it may be emitted at the timing when the subject's forehead contacts the forehead rest, the timing when the subject's chin is placed on the chin rest, or the like.

When the remote control means is configured to include such a signal acquisition means, the display control means switches the operation screen and the captured image on the screen of the display means based on the switching signal so as to display them. You may control the display of a display means. 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 captured image is displayed on the screen of the display means. In addition, for example, the display control means, based on the switching signal, deletes one of the operation screen and the captured image from the state in which both the operation screen and the captured image are displayed on the same screen of the display means. The display of the display means may be controlled. Further, for example, the display control means may add one of the operation screen and the captured image on the screen of the display means and add the other to display both the operation screen and the captured image on the same screen of the display means. The display of the display means may be controlled based on the switching signal so as to be displayed on the display.

For example, by switching and displaying the operation screen and the captured image on the screen, the examiner can easily give instructions to the subject while observing the screen where the operation screen and the captured image are switched manually or automatically. You can put it out or inspect the eye.

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

In addition, in the present embodiment, the optometry system includes a second operation unit (for example, the operation unit 302). The second operation unit is provided at a place apart from the optometry apparatus and operates the optometry apparatus. For example, in the present embodiment, the second operation unit may be provided in the remote operation means. As the second operation unit, a user interface such as a mouse, a joystick, a keyboard, a tablet terminal, a controller may be used.

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

In addition, in the present embodiment, the optometry system includes a second setting unit (for example, the control unit 107). The second setting unit assigns the second operation of the optometry apparatus to the second operation signal input from the second operation unit. The second setting unit may be configured to allocate one motion to the second operation unit, or may be configured to allocate a plurality of motions.

That is, in the present embodiment, it is possible to appropriately assign the operation to the first operation unit and the second operation unit by the first setting unit and the second setting unit. In other words, the operation for the first operation section and the second operation section can be appropriately set by the first setting means and the second setting means.

The first operation and the second operation are at least one of the operations performed when the eye to be inspected is examined using the optometry apparatus. As an example, an alignment operation for aligning the eye to be examined and the eye to be inspected, a photographing operation to image the eye to be inspected, a setting operation to set inspection conditions for inspecting the eye to be inspected, an inspection start operation to start inspection of the eye to be inspected, a jaw At least one of an adjusting operation for adjusting the height of the table and an adjusting operation for adjusting the position of the forehead support can be mentioned. Of course, the first operation and the second operation may be operations other than these. For example, there may be operations related to the examination of the eye to be inspected using the eye examination apparatus from the alignment between the eye examination apparatus and the eye to be examined.

The first setting unit and the second setting unit may be set so that at least a part of the same operation in the optometry apparatus is assigned to each of the first operation unit and the second operation unit. In this case, the first operation and the second operation may all be the same. As an example, the alignment operation and the adjusting operation may be assigned to the first operating section, and the alignment operation and the adjusting operation may be assigned to the second operating section. Further, in this case, the first operation and the second operation may partially overlap. As an example, the alignment operation and the imaging operation may be assigned to the first operation unit, and the alignment operation and the adjustment operation may be assigned to the second operation unit.

Further, the first setting unit and the second setting unit may be set so as to assign different operations in the optometry apparatus to the first operation unit and the second operation unit, respectively. That is, the first motion and the second motion may be different. As an example, the inspection operation may be assigned to the first operation unit and the alignment operation may be assigned to the second operation unit.

In the above description, the case where the first setting unit and the second setting unit set the first operation unit and the second operation unit so as to allocate a predetermined motion is illustrated, but the present invention is not limited to this. The first setting means and the second setting means may be set so that the first operation section and the second operation section are each assigned a subdivided operation of a predetermined operation. As an example, the first setting unit sets to the first operation unit such that the horizontal movement and the vertical movement movement of the alignment operation are allocated, and the second setting unit sets the second operation unit to the second operation unit. The movement operation in the front-rear direction of the alignment operation may be set.

For example, in the optometry system according to the present embodiment, the examiner operates the optometry apparatus from a remote place, and thus it is difficult to understand the sense of distance in the front-back direction in the alignment operation. By assigning the operation for each movement direction of the alignment operation to the first operation unit and the second operation unit, it is possible to reduce the possibility of contact between the subject and the optometry apparatus.

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

For example, by thus configuring the operation of the optometry apparatus by using the first operation section and the second operation section, the operator (that is, the examiner, the examinee, and the assistant) operating the optometry apparatus. Person, etc.) can be assigned an appropriate action according to the location and skill of the subject, the content of the action when examining the eye to be inspected, and the like. The examiner can easily inspect the eye to be inspected even if he/she is not in the space where the optometry apparatus is arranged.

In the present embodiment, when the optometry apparatus includes the above-described fundus imaging unit, at least one of the first setting unit and the second setting unit is an operation signal input from the first operation unit and the second operation unit. In addition, an operation for initiating imaging by the fundus imaging means (in other words, an imaging start operation) may be assigned. As an example, in the present embodiment, it may be set such that the imaging start motion is assigned to the operation unit operated by the examiner and the imaging start motion is not assigned to the operation unit operated by the subject. Therefore, even if the subject issues an operation signal for starting imaging, malfunction of the optometry apparatus is suppressed.

Further, 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 receives an operation signal input from the first operation section and the second operation section. An operation for aligning by the alignment means (in other words, an alignment operation) may be assigned. As an example, in the present embodiment, the alignment operation may not be assigned to the operation unit operated by the examiner, and the alignment operation may be assigned to the operation unit operated by the subject. The subject can grasp the sense of distance between the eye to be inspected and the device, and the alignment operation is performed by the subject, so that the alignment can be performed safely.

<Operation control means>
In the present embodiment, the optometry system includes operation control means (for example, the control unit 107). When the operation of the optometry apparatus is being executed by one of the first operation signal and the second operation signal, the operation control means prohibits the operation of the optometry apparatus by the other operation signal. ..

For example, the operation control unit prohibits the input of the other operation signal while the operation of the optometry apparatus is being executed by the operation signal of either the first operation signal or the second operation signal. The configuration may be such that the execution of the operation of the device is prohibited. Further, for example, when the operation of the optometry apparatus is being executed by one of the first operation signal and the second operation signal, the operation control unit prohibits transmission or reception of the other operation signal. Therefore, it may be configured to prohibit the operation of the optometry apparatus. In addition, for example, the operation control unit, for example, the operation control unit, while the operation of the optometry apparatus is being executed by one of the first operation signal and the second operation signal, The operation of the optometry apparatus may be prohibited by prohibiting the execution of the operation signal.

In the present embodiment, the operation of the optometry apparatus is executed by not assigning a predetermined operation to either the first operation unit or the second operation unit by the first setting unit and the second setting unit. It may be prohibited.

By such an operation control unit, switching to the control operation based on the other operation signal is suppressed while the control operation based on the one operation signal is being executed, and the examination of the eye to be inspected is efficiently and safely performed. be able to.

The operator who operates the optometry apparatus may be informed whether the operation of the optometry apparatus is executable or the operation of the optometry apparatus is prohibited. For example, the notification may be given by at least one of the display on the display unit and the voice guide.

<Operator information acquisition means>
In the present embodiment, the optometry system includes an information acquisition unit (for example, the control unit 303). The information acquisition unit acquires operator information which is information on an operator who operates the optometry apparatus. The operator information may be information related to the operator (for example, an examiner, an assistant, etc.). As an example, the face, name, affiliation, biographies, etc. of the operator can be cited. The operator's face may be acquired as an image (moving image or still image) of the operator. For example, the optometry system may be provided with a photographing means for photographing the operator.

That is, the operation screen 500 and the captured image 600 may be displayed at different timings. The first operation signal and the second operation signal may be combined, and the operation screen 500 and the captured image 600 may be displayed at the same timing based on the output of the first operation signal (second operation signal). ..

<Assignment of movement>
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 operation unit 300. it can. For example, the operation of the OCT apparatus 100 may be an operation for aligning the OCT apparatus 100 and the eye E to be inspected, setting for obtaining OCT data, starting an examination, adjusting the height of the chin rest 104b, and the like. (Details will be described later).

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

<Display of operator information>
The optometry system 1 can acquire the operator information of the operator who operates the OCT apparatus 100 (for example, the examiner D) and 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 bar code) 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 subject P who has entered the examination room 10 to the OCT apparatus 100, and the examination of the eye E using the OCT apparatus 100. The operation for performing will be described.

<Powering on the OCT device>
First, the examiner D turns on the power of the OCT apparatus 100. For example, the 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 operation 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 according 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.

<Display of operation screen on remote control unit>
The control unit 107 of the OCT apparatus 100 transmits the 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 causes the monitor 301 to display the received operation screen 500.

<OCT device operation allocation>
The examiner D inputs the operation signals for the OCT apparatus 100 to execute various operations to the operation unit 302 operated by the examiner D and the operation unit 101 operated by the subject P in advance. assign. The examiner D operates the operation screen 500 displayed on the monitor 301 to call the operation setting screen 503 for setting the allocation of the operation 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 unit 302 operated by the examiner D (displayed as the first operation unit in FIG. 5), and the subject. A box 503c for selecting an operation to be assigned to the operation unit 101 operated by P (displayed as a second operation unit in FIG. 5) is displayed.

The examiner D inputs an operation signal from the operation unit 302, an operation signal from the operation unit 101, or an operation signal from the operation unit 302 and the operation unit 101 for various operations of the OCT apparatus 100. Do or change. That is, it is selected whether the examiner D instructs, the examinee P instructs, or the examiner D and the examinee P instruct the OCT apparatus 100 to execute various operations.

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

In the present embodiment, since the examiner D is in the operation room 20 and the examinee P is in the examination room 10, the examiner D displays the operation screen 500 (for example, the anterior segment image 501) displayed on the monitor 301. By observing the captured image 500, the eye E of the subject P is indirectly confirmed. In the alignment between the OCT apparatus 100 and the eye E to be inspected, it is necessary to move the measurement unit 103 with respect to the eye E in the up-down direction, the left-right direction, and the front-back direction. However, since the examiner D looks at the eye E through the monitor 301, it is difficult to grasp the positional relationship between the eye E and the measurement unit 103. In particular, it is difficult to understand the positional relationship between the eye E to be measured and the measurement unit 103 in the front-rear direction (in other words, the sense of distance between the eye E to be measured and the measurement unit 103).

Therefore, the examiner D assigns the input of the operation signal for performing the alignment operation to the operation unit 101 operated by the subject P, so that the subject P can instruct the execution of the alignment operation. You may. The examiner D selects the box B1b corresponding to the alignment operation from the box 503c for selecting the operation to be assigned to the operation unit 101 (second operation unit) on the operation setting screen 503.

The control unit 303 of the remote control unit 300 transmits a selection signal generated by the selection of the box B1b to the control unit 107 of the OCT apparatus 100 via the shared server 400. The control unit 107 of the OCT apparatus 100 permits the operation unit 101 to input an operation signal for executing the alignment operation in accordance with the received selection signal.

For example, the alignment operation for performing the alignment between the OCT apparatus 100 and the eye E to be inspected in this manner may be assigned only to the operation unit 101. That is, only the subject P may be instructed to execute 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 the operation to be assigned to the operation unit 302 (first operation unit). In this case, since the selection signal due to the selection of the box B1a is not issued, the control unit 303 of the remote operation unit 300 prohibits the operation unit 302 from inputting the operation signal for executing the alignment operation.

Of course, the examiner D is not limited to the alignment operation, but an operation for setting the OCT apparatus 100 to obtain OCT data (setting operation) and an operation for starting an inspection using the OCT apparatus 100 (inspection start operation). ), an operation for photographing the eye to be inspected (imaging operation), an operation for adjusting the height of the chin rest 104b (chin rest adjustment operation), and the like are assigned to at least one of the operation unit 302 and the operation unit 101. As described above, each may be set.

For example, in this embodiment, the setting operation and the inspection start operation are assigned only to the operation unit 302. That is, it is set so that only the examiner D can instruct the execution of the setting operation and the inspection start operation. Further, for example, in the present embodiment, the chin rest adjustment operation is assigned to the operation unit 302 and the operation unit 101. That is, it is set so that the examiner D and the subject P can instruct execution of the chin rest adjustment operation.

<Turn on the shooting unit>
The inspector D turns on the power of the imaging unit 200 after finishing the assignment of the operation of the OCT apparatus 100. For example, the 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 operation unit 300 transmits the operation signal input from the power switch to the control unit 202 of the imaging unit 200 via the shared server 400. The control unit 202 of the image capturing unit 200 activates the image capturing unit 200 according to the received operation signal. When the image capturing unit 200 is activated, a completion signal indicating that the image capturing unit 200 has been activated is issued.

<Display of captured image on 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 unit 202 of the image capturing unit 200 transmits captured images 600 sequentially captured by the detector 201 to the control unit 303 of the remote control unit 300. The control unit 303 causes the monitor 301 to display the received captured image 600.

For example, on the monitor 301 observed by the examiner D, 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 simultaneously displayed in this manner. That is, the operation screen 500 and the captured image 600 are displayed on the same screen on the monitor 301.

<Induction of subject>
When the examiner D observes the captured image 500 displayed on the monitor 301 and confirms that the subject P has entered the examination room 10, the subject D instructs the subject P to sit in front of the OCT apparatus 100. put out. Further, when the examiner D confirms that the subject P is sitting in front of the OCT apparatus 100, the examiner D instructs the subject P to place his/her chin on the chin rest 104b of the OCT apparatus 100.

A detector 105 is provided on the chin rest 104b of the OCT apparatus 100. When detecting the load from the outside, the detector 105 detects that the jaw of the subject P is placed on the chin rest 104b. Further, the detector 105 converts this load into an electric 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 the eye E to be inspected is ready for inspection. Further, the control unit 107 transmits a determination result indicating that the eye E to be inspected is ready for inspection to the control unit 303 of the remote operation unit 300 via the shared server 400. The control unit 303 of the remote control unit 300 may display the message M1 (see FIG. 6) on the monitor 301 based on the detection result of the detector 105. For example, in the present embodiment, when it is detected that the eye E to be inspected is ready for inspection, a message is displayed to inform the examiner D that the next operation can be started.

When the examiner D guides the subject P to the OCT apparatus 100 and confirms that the examination of the subject's eye is ready, the examiner D selects a power switch (not shown) displayed on the monitor 301 to select the examination room. Turn off the electricity of 10. In the present embodiment, since the imaging unit 200 is a night-vision camera, even if the inspection room 10 is turned off, the captured image 600 is captured under night-vision, and the monitor 301 monitors the inspection room 10 and the subject P. You can observe the situation.

<Alignment of eye to be examined>
The examiner D observes the captured image 600 displayed on the monitor 301, and instructs the subject P to look at a monitor (not shown) included in the measurement unit 103. For example, the content of the instruction issued by the examiner D to the subject P may be displayed as a message on a monitor (not shown). Further, for example, a monitor (not shown) may display a fixation target for fixing the eye to be inspected. For example, after such a message is displayed for a certain period of time, the fixation target may be automatically switched. Of course, the message and the fixation target may be displayed at the same time.

Further, the examiner D observes the captured image 600 displayed on the monitor 301 and gives an instruction to 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 according to the start signal from the alignment start switch, and captures the anterior segment image 501 of the subject's eye E. At the same time, the alignment index image K1 is projected on the cornea of the eye E to be inspected. In addition, the control unit 107 uses the alignment index image K1 to detect the positional deviation of the corneal apex position (substantially the corneal apex position) of the eye E with respect to the measurement optical axis of the measuring unit 103, and performs automatic alignment.

FIG. 6 is an example of a 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 operation unit 300 via the shared server 400, and the control unit 303 causes the monitor 301 to display the anterior segment image 501. That is, the anterior segment image 501 of the eye E is displayed on the monitor 301 as the operation screen 500 of the OCT apparatus 100. The examiner D can confirm the alignment state between the OCT apparatus 100 and the eye E by observing the anterior segment image 501 displayed on the monitor 301.

In addition, in the present 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, the operation signal for executing the alignment operation is not input. At this time, a message indicating that the operation from the operation unit 302 is disabled may be displayed on the monitor 301 observed by the examiner D.

Of course, in addition to the operation unit 101 operated by the examinee P, an alignment operation is assigned to the operation unit 302 operated by the examiner D, and when the alignment by the examinee P fails, the examiner D May be able to perform the alignment.

<Adjustment of chin rest>
In the above automatic alignment, when the eye E to be inspected is displaced to a position higher or lower than the movement limit of the measurement unit 103 in the vertical direction, the movement of the measurement unit 103 is stopped midway, and the alignment is successful. May not be. Therefore, the examiner D observes the anterior ocular segment image 501 and adjusts the height of the chin rest 104b as necessary.

The examiner D may instruct the subject P to operate a jaw rest adjustment switch (not shown) provided on the operation unit 101 to adjust the height of the jaw rest 104b. For example, in FIG. 6, since the eye E to be inspected is in a high state with respect to the measurement unit 103, 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 according to the adjustment signal from the chin rest adjustment switch. When the 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 is lowered, the examiner D automatically aligns the subject P with the subject P. May be instructed to do again.

Of course, the examiner D may adjust the height of the chin rest 104b by operating the operation unit 302 of the remote operation unit 300 and selecting the 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>
The examiner D sets the conditions for starting the examination of the eye E when the alignment between the OCT apparatus 100 and the eye E is completed. The examiner D operates the operation screen 500 displayed on the monitor 301 to call a setting screen for setting the inspection condition of the OCT apparatus 100. Further, the examiner D 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 the inspection condition of the OCT apparatus 100 according to the received selection signal.

In this embodiment, an operation signal (first operation signal) issued by the operation of the operation unit 302 by the examiner D and an operation signal (second operation signal) issued by the operation of the operation unit 101 by the subject P. While 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 and the chin rest adjustment operation. For example, when the examiner D operates the operation unit 302, even if the subject P operates the operation unit 101, the input of the operation signal by the operation unit 101 is invalidated. Good. For example, the fact that the input of the operation signal by the operation unit 101 is disabled may be notified as voice from a speaker (not shown).

<Start of inspection>
When the examiner D sets the examination condition of the OCT apparatus 100, the examiner D starts the examination of the eye E to be examined. For example, the examiner D operates the operation unit 302 to select an inspection start switch (not shown) for starting the inspection 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 examination 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 the inspection by the OCT apparatus 100 according to the received start signal. Note that the control unit 107 may display a message indicating that shooting is started on a monitor (not shown) of the measurement unit 103 in response to the received start signal.

For example, the control unit 107 of the OCT apparatus 100 optimizes control for observing the fundus region of the eye E desired by the examiner D with high sensitivity and high resolution according to the start signal (for example, adjustment of the optical path length). , Focus adjustment, polarization state adjustment, etc.) and OCT data acquisition. The control unit 107 of the OCT apparatus 100 may generate a tomographic image of the eye E from the acquired OCT data and transmit the tomographic image to the control unit 303 of the remote operation unit 300 via the shared server 400. .. At this time, the control unit 107 may transmit to the control unit 303 in a state in which the resolution of the tomographic image is reduced or 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, the tomographic image 502 of the eye E to be inspected 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 inspect the eye E to be inspected even if the examinee D is away from the subject P.

In addition, for example, when the imaging by the OCT apparatus 100 is completed, the monitor (not shown) of the measurement unit 103 may be switched from the fixation target to a message indicating that the imaging is completed.

<Display of examiner information>
The optometry system 1 according to the present embodiment may present the operator P who operates the OCT apparatus 100 (for example, information about the examiner D) 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 individual user ID of the examiner D. It may have been done.

FIG. 7 is an example of the operator information 700 presented to the subject P. For example, the examiner D inputs the user ID when using the 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 calls the operator information corresponding to the user ID from the memory 402, and sends 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 the monitor. The operator information 700 may be displayed on a monitor provided separately from the OCT apparatus 100, or may be displayed on a monitor provided in the measurement unit 103 of the OCT apparatus 100.
