Next, the operation will be described. First, a case of performing suppression removal training by the vibration method will be described using this embodiment. The trainee first sets the training mode setting unit 21.
Is used to input whether the patient's inhibition eye is on the left or right. Next, the training method to be performed, the size of the target, the squint angle, and the presence or absence of blinking of the target are set. When blinking the target, set the blinking time and blinking interval. Further, the luminance of the target, the movement of the target, that is, the moving range and moving speed of the target, the number of repetitions of training, and the like are set.

These parameters are: training method, squint eye,
And by setting the minimum information such as squint angle,
Other setting items can be set automatically. Thereby, the operation at the time of setting can be simplified.

Further, the data corresponding to the set values relating to the training once set is supplied to and stored in the training mode storage unit 26 of the training storage unit 22. Therefore, in the case where similar training is performed next time, it is possible to read the set value already stored in the training mode storage unit 26 and perform the predetermined training according to the set value. As a result, the setting operation for training can be further simplified.

Here, when the movement or the position of the optotype is set by the training mode setting unit 21, the visual angle indicating which angle direction the optotype is displayed is displayed centering on the eye of the patient. The method of setting was adopted. This is because the display of the optotypes on the display panels 13a and 13b is
It is finally controlled by the two-dimensional coordinate positions on a and 13b, but in the case of strabismus correction training, it is important in which angle direction the target is displayed from the affected eye.

As described above, the data corresponding to the set values input from the training mode setting unit 21 is temporarily stored in the training mode storage unit 26 of the training storage unit 22, and then the optotype presenting process calculation unit 31. Is supplied to. The optotype presenting process calculation unit 31 reads out the optotypes for, for example, suppression removal training stored in the optotype storage unit 23 of the training storage unit 22 according to the setting values supplied from the training mode storage unit 26.

That is, first, the image data corresponding to a predetermined target for the affected eye, for example, the image data corresponding to "lion" stored in advance in the target storage for target eye 24 is read out, and then, Image data corresponding to a predetermined target for a healthy eye, which is stored in advance in the target storage unit for a healthy eye 25, for example, image data corresponding to “a cage” is read.

Next, the optotype presenting processing operation section 31 moves the read image data "lion" and "cage" according to the set values supplied from the training mode storage section 26 (change of display position). ), Predetermined image data is created. This image data is supplied to the image construction unit 35.

In the affected-eye image constructing unit 36 of the image constructing unit 35, the optotype corresponding to the image data supplied from the optotype presenting processing unit 31 (in this case, an image of "lion").
However, a predetermined one image signal is constructed so that it is displayed at the designated position on the display panel 13a or 13b. Similarly, in the healthy-eye image constructing unit 37, the optotype (the image of the “cage” in this case) corresponding to the image data supplied from the optotype presenting process calculating unit 31 is designated on the display panel 13a or 13b. A predetermined piece of image data is constructed so as to be displayed at the designated position.

The image data constructed in this way is
In the display panel control unit 38, the left and right display panels 13
Allocation processing and the like are performed on a and 13b. For example, the “lion” that is an image for the affected eye is displayed on the display panel 13 for the right eye.
“Cage” which is displayed in b and is an image for normal eyes is displayed on the display panel for left eye 13a.

The above-mentioned image data supplied to the image constructing unit 35 is supplied from the optotype presenting processing unit 31 to the display unit 1 via the display panel control unit 38, and the corresponding optotype is displayed. Since the series of processes described above is performed instantaneously, it is possible to display a moving image of the target on the display panels 13a and 13b according to the setting of the trainee.

Therefore, conventionally, a trainee manually operates the lens barrel of a large-sized amblyoscope to move the target by a few degrees around the oblique angle, or while maintaining a constant oblique angle.
The optotype was moved to the left or right, or the optotype was moved to the up, down, left, or right.
A moving image can be displayed by instantly changing the positions of the optotypes displayed on 3a and 13b. Therefore, the optotypes can be moved to the left or right by a predetermined angle around the oblique angle,
Limit the angle at which the target is moved left and right, move the target vertically and horizontally at a constant angular velocity, or move the target left and right or keep blinking while keeping the squint angle constant. Can be done easily.

Also, the patient can operate the patient input device 11 to move the optotype displayed on the display unit 1. The operation of the above embodiment in this case will be described by taking the "suppression removal training / chasing method" using "butterflies" and "nets" as targets.

First, the trainee sets the suppression eye to, for example, "right" by the training mode setting unit 21, and sets the "suppression removal / chase method" as the training method. Next, the size of the target is set, and further the training time and other necessary parameters are set. When the training mode setting unit 21 finishes setting the predetermined parameters, the data corresponding to the set parameters is supplied to the training mode storage unit 26, stored therein, and supplied to the optotype presenting process calculation unit 31. It

When predetermined data corresponding to the parameters set by the training mode setting unit 21 is supplied to the optotype presenting process calculation unit 31, the optotype presenting process operation unit 31 first causes the optotype presenting unit 23 to operate. The image data corresponding to the "butterfly" as the target for the healthy eye is read from the target storage unit 25 for the healthy eye. Next, the image data corresponding to the "net" as the target for the affected eye is read from the target storage for target eye 24.

The image data corresponding to each of the "butterflies" and the "nets" read out by the optotype presenting process calculating section 31 is subjected to a predetermined optotype presenting process operation there. That is, when the corresponding image data is processed and the “butterfly” is displayed on the display unit 1 in order to convert the size, brightness, etc. of the “butterfly” into a predetermined size or brightness value. ,
In order for the movement of the "butterflies" to be continuous and random,
For example, control data for controlling the display of "butterfly" is programmed.

Next, the image data and the control data corresponding to the "butterfly" processed by the optotype presenting process calculating section 31 are supplied to the healthy eye image constructing section 37, for example, the display of the built-in memory. An image corresponding to each image as a source of a predetermined moving image in a form of being copied to an address corresponding to a predetermined position determined based on the control data of the left-eye display panel 13a of the unit 1. The data is constructed respectively.

On the other hand, the image data corresponding to the “net” read out as the target for the affected eye from the target storage for target eye 24 by the target presenting calculation unit 31 is the target presenting process calculation. In the unit 31, the size, brightness, etc. of the "mesh" image is processed to convert it into a predetermined size or brightness value.
In addition, the predetermined movement information input by the patient using the joystick 12 provided in the patient input device 11 connected to the patient input unit 42 is displayed as “mesh” on the display panel 13b for the right eye of the display unit 1. Is converted into change information of the display position of and is supplied to the optotype presenting process calculation unit 31.

The optotype presenting processing operation section 31 uses the change information of the display position of the "mesh" on the display panel 13b for the right eye to display the image data corresponding to the "mesh" on the display panel 13 of the image data.
Control data for instructing the display position on b is created and supplied to the image construction unit 35.

In the image construction unit 35, the image data to be displayed on the right-eye display panel 13b is generated based on the image data corresponding to the predetermined optotype supplied from the optotype presenting processing unit 31 and the control data. Be built. as a result,
Corresponding to the operation of the joystick 12 by the patient,
The "net" is displayed at a predetermined position on the display panel 13b. That is, the optotype is controlled to move according to the patient's instruction.

In this way, the patient sees the patient displayed on the display panel 13b for the right eye on the "butterfly", which is the target for randomly moving healthy eyes displayed on the display panel 13a for the left eye. By operating the joystick 12 and moving the "net" toward the "butterfly" so that the movable "nets", which are the visual targets for the eyes, can be seen to overlap, it is possible to perform training as if playing a game. it can.

Further, the optotype presenting process calculating section 31 is provided with a comparing section 32, and predetermined information inputted from the patient input section 42, for example, display of "net" displayed on the display panel 13b. Data corresponding to position and display panel 1
Comparison with the data corresponding to the display position of the "butterfly" displayed on 3a can be performed.

Therefore, when the "net" catches the "butterfly" by the effort of the patient, the fact is recognized by the comparison unit 32, and a predetermined voice is output to the voice control unit 43, for example. A control signal indicating is supplied. The voice control unit 43 reads out predetermined voice data from the voice signal storage unit 30 according to the control signal supplied from the comparison unit 32, and outputs it to the voice output unit 46.

Alternatively, when the "net" catches the "butterfly" due to the patient's efforts, the comparing section 32 recognizes this and instructs the display panel control section 38 to display the display panel 1.
It is also possible to instruct to change the background colors of 3a and 13b. The display panel control unit 38 includes the comparison unit 32.
The background color of the display panels 13a and 13b is changed in accordance with the command from.

This allows the patient to be aware that the goal of this exercise of overlaying a "net" on a "butterfly" has been achieved.

A mirror 19a is provided inside the lens barrel so that the light from the viewing window 16a is reflected and emitted toward the eyepiece. In this case, the eyepiece portion of the lens barrel 18a is connected to the viewing window 16a so that it is located above the viewing window 16a. Therefore, the trainee can observe the patient's eyes not from the front but from above.

Alternatively, the lens barrel 18a can be installed so that its eyepiece portion is located on the side of the viewing window 16a. In this case, the trainee can observe the patient's eye from the side.

Similarly, one opening of the lens barrel 18b can be connected to the viewing window 16b. A supervisor eyepiece pad 17b is provided in the other opening (eyepiece portion). In addition, the mirror 1 is provided inside the lens barrel.
9b is provided so that the light from the viewing window 16b is reflected and emitted toward the eyepiece. In this case, the eyepiece portion of the lens barrel 18b is connected to the viewing window 16b so as to be located above the viewing window 16b. Therefore, the trainee can observe the patient's eyes not from the front but from above.

Alternatively, the lens barrel 18b can be installed so that its eyepiece portion is located on the side of the viewing window 16b. In this case, the trainee can observe the patient's eye from the side.

By connecting the lens barrels 18a and 18b to the viewing windows 16a and 16b in this manner, the trainee can observe the left and right eyes of the patient from above or from the side, respectively. It is possible to increase the degree of freedom when.

Further, in the eyepieces of the lens barrels 18a and 18b,
Since the supervisor eyepiece pads 17a and 17b are respectively provided, it is possible to prevent light from the outside from entering the inside of the lens barrels 18a and 18b and irradiating the eyes of the trainee. Therefore, the trainee can observe the patient's eye as an image that is easier to observe.

FIG. 5 is a sectional view of the lens barrel 18a, 18 shown in FIG.
It is a figure which shows the structure of the other Example of the display part 1 when making it possible to rotate each b.

The eyepiece of the lens barrel 18a can be rotated, for example, from a position above the viewing window 16a to a position lateral to the viewing window 16b. Alternatively, it can be rotated 360 degrees. Similarly, the lens barrel 18b has a viewing window
It is configured such that it can be rotated from a position above 6b to a side position. Alternatively, it can be rotated 360 degrees.

Therefore, the trainee (observer) is the lens barrel 1
By rotating 8a and 18b, the patient's eye can be observed from any direction. This increases the degree of freedom of posture when the trainee observes the eye of the patient, and enables the trainee to observe in a comfortable posture.

FIG. 6 is a diagram showing the configuration of still another embodiment of the display unit 1 in the case where the eye observation cameras 5a and 5b are provided in the lower portion in FIG.

The eye observation camera 5a is, for example, the display unit 1
It is fixed to the lower part of the patient's left eye so that the left eye of the patient can be imaged. The video signal corresponding to the left eye of the patient captured by the eye observation camera 5a controlled by the camera control unit 48 is supplied to the image output unit 41 and output to the eye observation monitor 9 connected thereto. As a result, the image of the left eye of the patient is displayed on the right side of the eye observation monitor 9.

Similarly, the eye observation camera 5b includes the display unit 1
It is fixed to the lower part of the patient so that the right eye of the patient can be imaged. The video signal corresponding to the right eye of the patient captured by the eye observation camera 5b controlled by the camera control unit 48 is supplied to the image output unit 41,
It is output to the eye observation monitor 9 connected there. As a result, the image of the right eye of the patient is displayed on the left side of the eye observation monitor 9.

Therefore, the trainee can display the eye movement of the patient on the external eye observation monitor 9 to observe it. This increases the degree of freedom of the posture of the observer and the distance between the patient and the observer, and allows the observer to observe the eye of the patient in a relatively comfortable posture.

In each of the above-mentioned embodiments, the predetermined target different from each other is presented to both eyes of the patient, but only one eye of the patient, for example, the affected eye is presented with the target. It is also possible to do so.

Further, in FIG. 2, for example, the viewing window 16a and the viewing window 16b provided on the display unit 1 are slid to the left and right, respectively, so that the viewing window 16a and the viewing window 16b are provided.
It is also possible to make the distance between them variable.
Accordingly, the distance between the viewing window 16a and the viewing window 16b can be adjusted according to the distance between the eyes of the observer. Here, for example, it is possible to provide a predetermined optical system so that the patient's eyes can be observed from the front even when the distance between the viewing window 16a and the viewing window 16b is changed. Therefore, the observer can observe the patient's eye in an optimal state.

Further, as shown in FIGS. 4 and 5, even when the lens barrels 18a and 18b are connected to the viewing windows 16a and 16b, for example, the viewing window 16a and the viewing window 16b provided in the display unit 1 are Slide left and right respectively,
It is also possible to make the interval between the eyepiece of the lens barrel 18a and the eyepiece of the lens barrel 18b variable. Thus, the distance between the eyepiece of the lens barrel 18a and the eyepiece of the lens barrel 18b can be adjusted according to the distance between the eyes of the observer. Even in this case, for example, as in the case of the viewing windows 16a and 16b described above, even when the distance between the eyepieces of the lens barrel 18a and the lens barrel 18b is changed, the patient's eyes are viewed from the front. It is possible to provide a predetermined optical system so that it can be observed. Therefore, the observer can observe the patient's eye in an optimal state.
