METHOD FOR ASSESSING BINOCULAR VISION IN STRABISMUS BASED ON CHROMOSTEREOPSIS Russian patent published in 2020 - IPC A61B3/00 

FIELD: medicine.

SUBSTANCE: invention relates to ophthalmology and is intended for assessing binocular vision based on chromostereopsis in patients with strabismus. Examination is carried out in a room with illumination of at least 500 lx in conditions of complete prismatic angle of strabismus compensation. On the monitor screen, 16 test images are successively presented, each of which consists of a square and a circle located inside it and has color characteristics with varying ratio of red and blue components from identical to as different as possible. Ability to stereotype by the patient's ability to determine the relative position of the figures in the sagittal plane is evaluated. Color characteristics of the square and the circle for each test image are calculated by the RGB system from R 127.5, G 0, B 127.5 to R 0, G 0, B 255 - for the blue square, R 255, G 0, B 0 - for red circle, and in each next test image ratio of red and blue components for each figure is changed by 8.5.

EFFECT: invention provides an assessment of the degree of stereoscopic disorder with prescribing a corresponding correction with a therapeutic purpose and possibility of using the method in patients with color vision disorders, as well as simple and easy to use.
