Epiretinal membrane related vascular changes in diabetic eyes evaluated with optical coherens tomography angiography

AIM: To evaluate the retinochoroidal microvascular circulation and anatomical structure of diabetic non-diabetic patients with epiretinal membrane (ERM) help optical coherence tomography angiography (OCT-A) compare them healthy control subjects. METHODS: In this prospective, cross-sectional study, a total 165 eyes were evaluated, including 50 ERM, 54 idiopathic ERM (iERM) patients, 61 controls. Macula disc was performed by OCT-A. Macular vessel density (VD) ratio evaluated dividing VD foveal region parafoveal region. Statistical calculations at 95% confidence interval. RESULTS: superficial values cases lower than that in group, while higher cases. deep all quadrants, except fovea. The width avascular zone (FAZ) area significantly groups, FAZ lowest iERM group. but there no significant difference between groups. group CONCLUSION: Diabetic ERMs differ their mechanism formation clinical presentation, as well effect on retinal vascular structures. If relationship increase thickness integrity can be demonstrated OCT-A, then, OCT-A used guide for prognosis.
