Abstract
Background: Diabetic retinopathy (DR) is one of the most common causes of vision loss in diabetic patients. Fluorescein angiography provides valuable additional information compared to clinical examination or fundus photography but it has many contraindications. The aim of this study was to analyze the (FAZ) in Eyes for both groups using (OCT angiography). Methods: This study was a cross sectional case-control study. The study involved (78 eyes) of 40 cases "divided equally into two groups", (38 eyes) of 20 diabetic patients with non-PDR (18 bilateral & 2 unilateral) and (40 eyes) of 20 Healthy non-diabetic subjects. Results: The mean FAZ (mm²) was significantly higher in the Diabetic retinopathy group in comparison to the control group. There was a statistically highly significant difference between the two study groups in both the Superficial & Deep vessel density (%). The mean Superficial & Deep vessel density (%) were significantly higher in the healthy controls group in comparison to the Diabetic retinopathy group. Insignificant negative correlation was found between BCVA and the FAZ (mm²). Insignificant positive correlation was present between BCVA and the Superficial & Deep vessel density (%). There was insignificant negative correlation between the FAZ (mm²) and Superficial & Deep vessel density (%). There was a statistically significant positive correlation (P value
