QUANTITATIVE ASSESSMENT OF MACULAR HEMOPERFUSION IN PATIENTS WITH NONPROLIFERATIVE DIABETIC RETINOPATHY

Abstract

The purpose of the work is to study macular hemoperfusion in patients with nonproliferative diabetic retinopathy according to optical coherence tomography with angiography of the macula.Material and methods. The ophthalmologic examination of patients with diabetes mellitus complicated with non-proliferative diabetic retinopathy, which constituted the main group, and patients without eye pathology, who formed the control group, was conducted. All the patients of the main and control groups were subjected to standard ophthalmologic examination and optical coherence tomography with angiography of the macula.Results. The results of the study showed the reliability of differences in terms of maximum correctable visual acuity, intraocular pressure, perfusion area at the «chorionic capillaries» level, total capillary pattern density at the «superficial plexus» level and total capillary pattern density at the «deep plexus» level of the main and control groups.Conclusion. As a result of the examination of the patients, a violation of the hemoperfusion of the inner and outer layers of the retinal macular zone at the level of the capillary link was found according to optical coherence tomography with angiography of the macula in patients with nonproliferative diabetic retinopathy.
