A STUDY TO CORRELATE OPTICAL COHERENCE TOMOGRAPHY PARAMETERS WITH VISUAL ACUITY IN PATIENTS WITH DIABETIC MACULAR EDEMA

Aims: To correlate various Optical Coherence Tomography (OCT)para meters with Visual Acuity (VA) in patients with Diabetic Macular Edema (DME). To determine which OCT parameter correlates more with Vision. Design: It is a hospital based cross-sectional prospective study with 150 eyes of 120 patients done for a period of 3yrs. Methods: Patients with DME were subjected to Spectral Domain (SD) - OCT imaging. Total 7 OCT parameters were analysed. Central Foveal Thickness (CFT), Intra-retinal cystoid spaces, Disorganization of Retinal Inner Layers(DRIL), Hyper-reflective foci(HRF), sub-foveal neuro sensory detachment, Ellipsoid Zone(EZ)disorganization, VitreoR etinal(VR)-interface abnormalities like Epiretinal Membrane(ERM), Vitreo Macular Adhesion(VMA) and Vitreo Macular Traction(VMT). STATISTICAL ANALYSIS : The data was analyzed using SPSS version 29 statistical software. Pearson coefficient was used to test for correlations.
