| Popis: | Introduction Diabetic retinopathy (DR) increases the risk of blindness by 25 times. Advanced researchs are justified for better management, leading to the role of Optical Coherence Tomography-Angiography (OCT-A), a new non-invasive imaging technique exploring retinal vascularization. Our purpose is to identify microvascular macular anomalies of DR on OCT-A with qualitative and quantitative evaluation of their impact on retinal vascularization. Patients and methods This is a descriptive cross-sectional study where 120 eyes of 66 diabetic patients were enrolled. All patients were diabetic and went through OCT-A imaging. Results Microanevrysms were identified in both superficial capillary plexus (SCP) and deep capillary plexus (DCP) where they were more frequently visualized. Macular edema was present in 16,7% of cases in the SCP, and in 30% in DCP. Edema spaces were more frequently present in DCP (p Highlights • Retinal microvascular abnormalities on OCT-A are observed in diabetic retinopathy and are proportional to its severity. • Deep capillary plexus was more severely affected than superficial capillary plexus. • The assessment of macular ischemia could be based on the identification of areas of vascular rarefaction. • Quantitative assessment of vascular density and the study of the foveal avascular zone can assess the macular ischemia |
