BLOOD FLOW VELOCITY IN THE ORBITABAL ARTERIES WITH PROGRESSIVE MYOPIA BEFORE AND AFTER XENOSCLEROPLASTY

Аннотация

Relevance. We studied the Doppler pattern of blood flow velocity in patients with retinal dystrophy. Destruction of the main stems of fern-like crystallization of tears was noted. Purpose of the study. To study the features of the Doppler pattern of blood flow velocity at various stages of development of chorioretinal retinal dystrophies. Material and research methods. Clinical observations and studies were performed on the healthy eyes of 10 volunteers (20 eyes) and 24 patients with various eye pathologies and varying degrees of severity (24 eyes), who were undergoing inpatient and outpatient treatment in (2020-2021). Results. Evaluation of the effectiveness of xenoscleroplasty at various degrees of development of progressive myopia showed that despite the differences in severe complications, such as advanced chorioretinal complications after xenoscleroplasty, blood flow speed accelerates in all clinical observations. But in the early stages of myopia progression, the blood flow velocity in all 4 arteries accelerates by an average of 50%, in the second group of patients the blood flow accelerates by an average of 25%, and in severe retinal lesions it accelerates.. by 15% on average. Conclusions. After the operations, improvements in visual functions were noted due to the long-term effect of xenoplast on the acceleration of blood flow in the basins of the orbital artery, the central retinal artery and the posterior ciliary arteries of the eyeball
