Granted: 2022-03-18
Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to ophthalmology. Patient is presented with a test object, and the position of fixation of eyes of the patient on the test object in each of its positions is determined. Parameters characterizing the state of oculomotor muscles are calculated. Diagnosis is carried out using a video eye tracking. Patient is put on a structure consisting of a spectacle frame to which two infrared cameras and a laser pointer projecting a test object onto the screen are attached. Structure is connected to a personal computer with a preset program for processing results. Reference point for measuring the angle of strabismus is the centre of the pupil of the fixing eye; the deviation value is automatically calculated during eye movement depending on the displacement of the pupil from the initial position. Measurement is carried out in nine directions of gaze with and without correction with formation of report, including photographs, video recording and graph of change of eye positions during examination with automatically calculated deviation angles in degrees, prism dioptres and millimetres. If the same deviation value is determined in all gaze directions, then concomitant strabismus is diagnosed. If deviation values differ in different directions of gaze, then unconjugate strabismus is diagnosed. 
     EFFECT: method enables to accurately measure the angle of strabismus in different gaze directions in natural conditions in a dynamic mode, to determine the type of strabismus.
