DETERMINATION THE SIGNIFICANCE OF OCT-ANGIOGRAPHY IN THE DIAGNOSIS AND TREATMENT OF MACULAR EDEMA DUE TO THE BRANCH RETINAL VEIN OCCLUSION

Purpose: to determine the diagnostic significance of the indicators obtained during optical coherence tomography angiography(OCT-A) in the diagnosis and treatment of patients with macular edema (MЕ) due to the branch retinal vein occlusion (BRVO).Material and methods: 54 patients were examined and treated with a diagnosis of ME due to BRVO. We analyzed and described the quantitative changes that are detected using OCT and OCT-A before and after combined treatment, as well as a correlation analysis between functional indicators and indicators obtained using OCT and OCT-A before treatment.Results. During the treatment there was an insignificant decrease of vascular density in all areas under study in the deep vascular plexus (DVP) and superficial vascular plexus (SVP), as well as a decrease of density in the peripapillary plexus and a decrease the thickness of the retinal nerve fiber layer. In the correlation analysis a direct strong relationship was detected between the indicators of central retinal sensitivity and the total density in the DVP and SVP before the treatment.Conclusion. OCT-A is a highly informative method for diagnosing, monitoring and evaluating the effectiveness of the treatment of ME due to BRVO and can also be used for topographyoriented combined laser treatment.
