A Comparative Study of Central Foveal Thickness in Nondiabetics Versus Diabetics Without Retinopathy Using Spectralis OCT

Abstract

Purpose: To compare the central foveal thickness (CFT) in diabetics without retinopathy versus nondiabetics using optical coherence tomography (OCT). Methods: The study was done as a comparative cross-sectional study among two groups with 30 subjects in each group. Group A was of diabetics without retinopathy and Group B was of nondiabetics. Patients with diabetic retinopathy, diabetic macular edema, other macular diseases, history of laser treatment, intra vitreal injections, chronic glaucoma, previous eye surgeries, and hypertension were excluded from the study. CFT of the two groups was measured using OCT. Results: All the data were analyzed with a statistical software package SPSS version 16.0. The mean CFT in the diabetics without retinopathy group was found to be 225.97 ± 21.20 µm, and in nondiabetic group it was 234.57 ± 34.68 µms. Conclusion: The study showed that CFT was slightly lower in diabetics without retinopathy when compared to nondiabetics, but the value was not statistically significant (P-value: 0.091).
