Abstract
To develop a device with broad functionality for treatment amblyopia. methods. Analysis of functionality and technical characteristics of devices for amblyopia treatment and the development of multifunctional apparatus. results. The full-color light transmitters (i.e., LEDs) are used in device. It provides the radiation withfull color spectrum. There are several directions of movement of stimuli which are presented on the display: horizontally from left to right or from right to left, vertically bottom-up or top-down, multidirectionally from the center of the display to the periphery or from the periphery of the display to the center, in a circumferential or helical pattern clockwise or counterclockwise. The period of motion of the stimuli varies from 0.25 to 4 seconds in increments of 0.25 seconds. Pulse modulation is 0-20 Hz. Light intensity is 0.1-3.0 cd. The duration of one treatment session is 1-7 min. The characteristic property of the device is multiprogram operating, i.e., several modes are switched consistently in the course of one session. Operating modes are customized for each patient. Computer control provides reprogramming of the device when assigning new tasks. Light-emitting display can be placed in the cone or be made as external component (rectangular-, quadratic-, or round-shaped). Conclusions. Stimulation of visual analyzer is performed with full-color light stimuli which move in various directions or rotate. Adjustment of modulation frequency and movement rate of the stimuli allows to change stimulation mode temporally and spatially. The device can be used in clinical and domestic settings to treat amblyopia, myopia and computer vision syndrome as well as to prevent eye fatigue.
