Evaluation of Diabetic Macular Edema Using Optical Coherence Tomography and Its Correlation with Visual Acuity: A Cross-Sectional Study

Abstract

Background: Diabetic macular edema (DME) is the leading cause of vision loss in patients 
with diabetic retinopathy. Optical coherence tomography (OCT) is a non-invasive imaging 
modality that allows quantitative and morphological assessment of macular changes. 
Objective: To evaluate the structural features of DME using OCT and to analyze their 
correlation with best corrected visual acuity (BCVA) in diabetic patients.
