FIELD: medicine.SUBSTANCE: invention is referred to the field of medicine, namely ophthalmology, and can be used for early preclinical diagnostics of progression of dystrophic alterations of retina periphery. The method of ultrasound biomicroscopy is used to detect structural spatial areas of retina with altered value of echodensity ratio. If in one of the retina sectors there is the detection of at least one disruption of adhesion of outer retina layers to inner choroid layers with formation of closed optically transparent curvilinear surface, with the bulge directed towards hyaloid body with the length from 50 mm to 500 mm, and/or in form of fixation on the inner retina surface by one structural spatial alteration in form of open curvilinear surface, directed with its open part towards the retina tissue and with the bulge directed towards hyaloid body with the length from 50 mm to 500 mm, and the echodensity ratio of open curvilinear surface lies within the range from 20% to 70% of echodensity ratio of retina, and one local optically transparent longitudinal dissection of retina layers, the distance between retina layers is in the range from 50 mm to 500 mm, the length of dissected sections is 50 mm to 5,000 mm, and the dissected inner section of retina is bent towards hyaloid body and protrudes by more than 40 mm, the conclusion is made on progression of dystrophic alterations of retina periphery.EFFECT: method provides for expansion of diagnostic tools range.1 dwg, 6 dwg, 3 exИзобретение относится к медицине, а именно к офтальмологии, может быть использовано для диагностики раннего доклинического прогрессирования дистрофических изменений периферии сетчатки. Выявляют методом ультразвуковой биомикроскопии структурные пространственные зоны сетчатки с измененной величиной коэффициента акустической плотности. Если в одном из секторов сетчатки фиксируют, по крайней мере, одно нарушение прилегания наружных слоев ткани сетчатки к внутренним слоям хориоидеи с формировани
