Abstract: Background: Diabetic macular edema (DME) is the major cause of visual deterioration in diabetic retinopathy.1, 2India is known as the "Diabetic capital of the world". Diabetic retinopathy is one of the microvascular complications of DM which affects 1 out of 3 patients with diabetes resulting in poor quality of life in patients with severe DR.3, 4Aims: Evaluate the correlation of visual acuity with the type of macular edema on Optical coherence tomography (OCT) in Type 2 Diabetes mellitus (T2DM) patients and also to find the association of visual acuity with the central subfield thickness. Settings and Design: A cross sectional study Methods and Material: A cross sectional study is done on 90 eyes of na?ve T2DM patients who had Macular edema from February 2021 to August 2022 at our tertiary eye care Hospital. Statistical analysis used: The Statistical software namely SPSS 22.0, and R environment ver.3.2.2 were used. Results: 29 patients had Sponge like retinal thickness (SLRT) with visual acuity of LogMAR 0.728, 19 patients had Cystoid macular edema (CME) with visual acuity of LogMAR 0.894, 8 patients had Serous retinal detachment (SRD) with visual acuity of LogMAR 1.182, 8 patients had Foveal tractional retinal detachment (FTRD) with visual acuity of LogMAR 1.307, 7 patients had Taut posterior hyaloid membrane (TPHM) with visual acuity of LogMAR 0.759, 19 patients had combined type DME with visual acuity of LogMAR 1.317 and Central subfield thickness (CST) is noted in all patients. There was a linear correlation between visual acuity and the central subfield thickness (p=0.000). Conclusions: Majority of the patients had SLRT with good visual acuity, less no of patients had TPHM with fair visual acuity and combined pattern had poor visual acuity. There was a linear correlation between visual acuity and the central subfield thickness (p=0.000).
