Comprehensive study of the state and relationship of choroidal and regional hemodynamics in retinal vein occlusion in young women

Abstract

Purpose. To study the relationship between choroidal and retinal hemodynamics of the eyes in retinal vein occlusion (RVO) in young women to determine the features of their clinical course. Material and methods. The main group included 15 women (15 eyes), whose age ranged from 35 to 45 years, averaging 39.7±4.0 years. 20 somatically healthy women of comparable age were included in the control group. In addition to standard examination methods, all women underwent a comprehensive study of chorioretinal hemodynamics. The linear velocity of blood flow (LVBF) in the posterior short ciliary arteries (PSCA) was evaluated using a multifunctional ultrasound diagnostic device Logiq e (General Electric, USA). Macular blood flow features were studied using an optical coherence tomograph in angiography mode RTVue-100 (Optovue, Inc., USA). A comparative analysis of the studied indicators between the groups was carried out. Results. The results of the study revealed the presence of an interrelated statistically significant decrease in choroidal and retinal hemodynamics in young women with RVO relative to the group of healthy women (p<0.001). Conclusion. Taking into account the revealed direct relationship between choroidal and retinal hemodynamics in women with acute respiratory infections, we consider it appropriate and necessary to perform a simultaneous comprehensive study of various components of the hemodynamics of the posterior segment of the eye in the presence of this pathology: LVBF in the PSCA by color Doppler mapping and macular blood flow by OCT in angiography mode. These data can significantly expand the diagnostic capabilities of identifying the severity of the clinical course of acute respiratory infections and help predict the possible formation of neovascularization.
