Aim:To detect retinal changes in patients with type 2 Diabetes prior to vascular signs without diabetic retinopathy or with mild non proliferative diabetic retinopathy.
Methods:A cross-sectional study was performed in three groups: Patients without diabetes (Group A), Patients with type 2 diabetes without diabetic retinopathy (Group B), Patients with diabetes with mild diabetic retinopathy (Group C). Analysis of retinal layers was performed using Topcon 3D OCT. Macular scans were analyzed with regard to: retinal nerve fiber layer thickness, central subfoveal retinal thickness and average macular thickness.
Results:In total, 60 patients were included in this study, of which 16 (26.67%) were classified into control group (Group A), 28 (46.67%) classified as diabetic patients with no diabetic retinopathy (Group B) and 16 (26.67%) classified as mild diabetic retinopathy (Group C). Quantitative analysis with using Topcon 3D OCT showed that the mean retinal nerve fiber layer was thinner in diabetics without diabetic retinopathy group
