(composition)
FIG. 1 shows the entire system of the embodiment. The system of FIG. 1 is constructed, for example, in a general hospital with an ophthalmology department. The system of FIG. 1 includes ophthalmic devices 11, 12, 13. The ophthalmic devices 11, 12, and 13 include different models. The ophthalmic devices 11, 12, and 13 are connected to the network line 10. The network line 10 is constructed by a LAN or an Internet line. The line standard is not particularly limited, and existing ones are used. The connection between the ophthalmic devices 11, 12, 13 and the network line 10 may be wired or wireless, and optical communication or the like can also be used.

The management server 15 is connected to the network circuit 10. The management server 15 handles an electronic medical record of a hospital that operates the system of FIG. The mobile terminal 14 is a mobile terminal held by a subject who receives a diagnosis using the ophthalmic devices 11, 12, and 13. In the following description, the mobile terminal 14 will be lent to the subject by the hospital side, carried around by the subject in the hospital, and the examination will be performed by the examiner. Depending on the type of ophthalmic apparatus and the content of the examination, the subject may operate the ophthalmic apparatus.

The mobile terminal 14 includes an interface for operation and a display (for example, a liquid crystal display device, an EL display device, etc.) for displaying various images. Examples of the mobile terminal 14 include tablets, smartphones, notebook PCs, and the like. The data that can be accessed from the mobile terminal 14 is protected by various authentication technologies (password authentication, biometric authentication, etc.), and various data (examination contents by an ophthalmic device, electronic medical record contents, etc.) can be accessed without limitation. Do not mean. As the mobile terminal, one having a reference numeral 14 is typically shown, but usually, a plurality of mobile terminals exist in the system.

The ophthalmic information processing device 100 performs processing related to displaying the image of the eye to be inspected (for example, fundus image, anterior segment image, etc.) acquired by the ophthalmic devices 11, 12, and 13 on the mobile terminal 14. The display 14a of the mobile terminal 14 has various standards such as screen size and pixel density, and even if the image data output by the ophthalmic apparatus 11 is displayed as it is, accurate information may not be displayed.

Regardless of the type of ophthalmic device, an operation (generally called alignment) that determines the relative positional relationship between the eye to be inspected and the device is required. In this operation, an image of the anterior segment of the eye to be inspected is taken, and the position of the anterior segment in the imaging screen is adjusted by moving the device side, the subject side, or both. In addition, the image of the anterior segment of the eye is important for confirming the condition of the eye to be inspected. In this sense, most ophthalmic devices have a function of capturing an image of the anterior segment of the eye (anterior segment image).

Therefore, in displaying the image of the anterior segment on the display 14a of the mobile terminal 14, the anterior segment of the eye to be inspected is in an appropriate state, that is, the observer (one or both of the subject and the examiner) is in the anterior segment. It needs to be done in a state where it can be clearly grasped as an image. The process for this is performed in the ophthalmic information processing apparatus 100.

FIG. 2 shows a block diagram of the ophthalmic information processing apparatus 100. The ophthalmic apparatus 100 is installed inside a server or an ophthalmic apparatus connected to a network. The ophthalmic information processing device 100 includes an image data receiving unit 101, a display standard acquisition unit 102, a display form selection unit 103, a data communication unit 104, an ophthalmic device model name acquisition unit 105, a data storage unit 106, and a display form conversion unit 107. ..

The ophthalmic information processing apparatus 100 is configured by using commercially available hardware for a PC (personal computer), a workstation, or a data processing server. Each functional unit shown in FIG. 2 is realized by installing application software that realizes the illustrated function on a computer and starting the application software.

A part or all of each functional unit shown in FIG. 2 may be configured by a dedicated arithmetic circuit. In addition, a functional unit configured by software and a functional unit configured by a dedicated arithmetic circuit may coexist. For example, each functional unit shown in the figure is composed of electronic circuits such as a CPU (Central Processing Unit), an ASIC (Application Specific Integrated Circuit), and a PLD (Programmable Logic Device) represented by an FPGA (Field Programmable Gate Array).

Whether each functional unit is configured by dedicated hardware or software by executing a program on the CPU is determined in consideration of the required calculation speed, cost, power consumption, and the like. Although there are the above-mentioned differences, configuring the functional unit with dedicated hardware and configuring it as software are equivalent from the viewpoint of realizing a specific function.

The image data receiving unit 101 receives the image data of the image of the eye to be inspected obtained by one or more of the ophthalmic devices 11, 12, 13. This image includes an anterior segment image of the eye to be inspected. Of course, SLO images and OCT images may be included (this depends on the function and model of the ophthalmic apparatus).

The display standard acquisition unit 102 acquires the standard information of the display 14a of the mobile terminal 14. Factors that determine the display standard include screen scale, screen size, resolution (number of pixels), and screen density (number of pixels per unit area). Of course, it is also possible to handle the types of standards used by those skilled in the art as industry standards. In this example, the display standards of mobile terminals (tablets and smartphones) on the market are examined in advance, and information on which standard is acquired is acquired by the display standard acquisition unit 102. FIG. 3 shows a list of examples of standards handled by the display standard acquisition unit 102.

The display form selection unit 103 selects the display form of the screen to be displayed on the display 14a based on the standard of the display 14a of the mobile terminal 14 acquired by the display standard acquisition unit 102. The display form is prepared in advance corresponding to the standard of FIG. In this example, when the anterior segment image is displayed on the display (for example, display 14a) of the mobile terminal to be used, the dimension of the diameter R (see FIG. 4) of the iris portion on the display is 25 mm or more. A display form adjusted to the scale is prepared in correspondence with the display standard of FIG. 3, and the display form corresponding to the display standard of the mobile terminal acquired from the display form is selected. Further, in this display form, the display of various information and the display of icons used in the GUI are set to a size that is easy to see and easy to use.

FIG. 4 shows a state in which the front eye portion image is displayed on the display 14a of the mobile terminal 14. Here, the screen is set so that the diameter R of the iris portion is 25 mm or more. A plurality of icons 15 for operations using the touch panel function are displayed on the screen of the display 14a. Reference numeral 16 is an area on the screen on which the image of the anterior segment of the eye to be inspected is displayed.

In addition, the display form corresponding to the display standard of the mobile terminal displays a display other than the image of the eye to be inspected (icon display for GUI, etc.) when the image of the eye to be inspected acquired by the ophthalmic apparatus is displayed on the corresponding display. The layout including it has been adjusted so that it does not interfere with observation or examination. By doing so, for example, the alignment of the eye to be inspected and the ophthalmic apparatus using a mobile terminal can be performed without any trouble.

Further, the display form selection unit 103 selects a display form in which the display is performed on the display 14a in a layout corresponding to the model and function of the ophthalmic apparatus. The appropriate screen display form (layout) differs depending on the type of ophthalmic device. Therefore, a screen layout format corresponding to each ophthalmic device is prepared in advance, and a display form of the layout corresponding to the ophthalmic device being used is selected. The display form is required for each ophthalmic device and each display standard of the terminal. That is, a plurality of display forms to be selected by the display form selection unit 103 are required depending on the combination of the types of the ophthalmic apparatus and the terminal. Specifically, a plurality of display forms are prepared in advance according to the combination of the model names of the ophthalmic device and the mobile terminal, and the formats are stored in the data storage unit 106. The type and model number of the ophthalmic apparatus are managed by identification information (for example, ID number, etc.), and the above-mentioned display form is prepared according to the identification information.

The data communication unit 104 communicates with the ophthalmic devices 11 to 13 and the management server via the network line 10. FIG. 6 shows an example of data transmitted from the ophthalmic devices 11 to 13 and data transmitted from the mobile terminal 14. It should be noted that it is also possible to directly communicate with the ophthalmic devices 11 to 13 without going through the network line 10.

The data storage unit 106 stores data necessary for the operation of the ophthalmic information processing device 100 (for example, the data of FIG. 3), data obtained as a result of the operation, and data received by the ophthalmic information processing device 100 (input data). NS. In addition, the data storage unit 106 stores data related to the above-mentioned display form.

The display form conversion unit 107 converts the image of the eye to be inspected obtained from the ophthalmic devices 11 to 13 into the display form selected by the display form selection unit 103. The converted image is sent from the data communication unit 104 to the mobile terminal 14, and is displayed on the display 14a.

(Example of processing)
Hereinafter, an example will be described in which the examiner operates the ophthalmic apparatus using a tablet (portable terminal) to perform ophthalmic measurement of the subject. The tablet to be used is lent to the subject by the hospital, but it is not necessarily limited to that. For example, it is possible to use a mobile terminal owned by the subject. In this case, the application software for performing the same operation as the mobile terminal 14 of FIG. 1 is downloaded to the mobile terminal owned by the subject.

FIG. 5 shows an example of processing. When the process is started, the subject is first accepted at the hospital reception (step S101). This reception may be performed in a format that is handled by the person in charge at the counter, or may be an electronic reception by operating a touch panel or a smartphone. As a result of the reception and the examination by the doctor, the examination contents of the subject are determined (step S102). Up to this point, the process is the same as in a normal hospital. In this example, an eye examination using a specific ophthalmic device is determined as the examination content.

The designated mobile terminal 14 is handed to the subject whose examination contents have been decided by the hospital side, and goes to the designated ophthalmic device (in this case, the ophthalmic device 11). Therefore, the mobile terminal 14 is handed to the examiner, and the subsequent operation of the mobile terminal 14 related to the ophthalmic apparatus is performed by the examiner. First, the mobile terminal 14 is operated by the examiner, and communication is performed between the mobile terminal 14 and the ophthalmologic device 11. (Step S103). This communication may be performed directly between the mobile terminal 14 and the ophthalmic device 11 using wireless communication or optical communication, or may be performed via the network line 10. Through this communication, the ophthalmic device 11 recognizes the identification information of the mobile terminal 14, while the mobile terminal 14 recognizes the identification information of the ophthalmic device 11.

At this time, the mobile terminal 14 also accesses the ophthalmic information processing device 100, and the ophthalmic information processing device 100 recognizes that the ophthalmic device 11 and the mobile terminal 14 are paired to start the examination. That is, in the ophthalmology information processing device 100, the ophthalmology device 11 and the mobile terminal 14 are linked. At this time, the ophthalmic information processing device 100 acquires the ID (identification information) of the ophthalmic device 11 and the ID (identification information) of the mobile terminal 14. As a result, the ophthalmic information processing device 100 recognizes information regarding the specifications of the ophthalmic device 11 and the mobile terminal 11.

In this process, the standard of the display 14a is based on the model data of the ophthalmic device 11 (information for identifying the model name and model of the ophthalmic device 11) acquired in step S103 and the standard of the display 14a on the mobile terminal 14 (see FIG. 3). And the display form corresponding to the model number (model) of the ophthalmic apparatus 11 is selected.

After that, the mobile terminal 14 is operated by the examiner, and the ID of the subject (the ID is given in advance by the hospital side) is input to the mobile terminal 14 (step S105). With the input of this ID as an opportunity, the mobile terminal 14 can be used as an operation terminal to operate the ophthalmic apparatus 11, and the ophthalmic apparatus 11 is operated (S106).

At this time, the image data of the image of the eye to be inspected obtained by the ophthalmology device 11 is sent to the ophthalmology information processing device 100, converted into the display form selected in step S104, and sent to the mobile terminal 14. The image converted into the display form selected in step S104 is displayed on the display 14a, and the ophthalmic apparatus 11 is operated by the examiner using the mobile terminal 14 while viewing the image. Here, in the self-ophthalmology device in which the subject operates the ophthalmology device by himself / herself, the subject himself / herself operates the ophthalmology device 11 using the mobile terminal 14. (Step S106).

For example, the display 14a displays an image of the anterior segment of the eye to be inspected converted into a display form suitable for the ophthalmic apparatus 11 and the display 14a, and the examiner operates the mobile terminal 14 while looking at the image to perform the alignment process. conduct. Then, when the examination by the ophthalmologic apparatus 11 (for example, taking a fundus image) is completed, the measurement is completed (step S107), and the result is transmitted to the management server 15.

(Superiority)
As shown in FIG. 3, there are various standards for the display of the mobile terminal, but when the ophthalmic information processing device 100 is used, the image of the eye to be inspected obtained by the ophthalmic device is displayed on the mobile terminal such as a tablet or a smartphone. In addition, the image information of the eye to be inspected is displayed in a format that is not impaired. Therefore, the operation of the ophthalmic apparatus using the mobile terminal and the observation using the image of the eye to be inspected displayed on the display of the mobile terminal can be performed without any trouble. In addition, it is possible to obtain an advantage that a person concerned such as a subject or a doctor can see a diagnostic image at a place away from the ophthalmic apparatus.
