Abstract: Introduction-Diabetic retinopathy is one of the most frequent complication of diabetes. Diabetic macular oedema (DME) is the largest cause of visual acuity loss in nonproliferative diabetic retinopathy. So study was done to study the relation betwwen morphological features of retinal layers and best corrected visual acuity in diabetic macular oedema. Material and method-it was a hospital based descriptive observation study done in Anand Hospital and Eye Centre, Jaipur over a period of one year. Detailed history, examination, investigation were made. Chi square test of independence, correlation coefficient, univariate and multivariate analysis were used for statistical analysis. Result- Statistical relation between Visual Acuity with status of ELM and IS/OS was found highly significant (p< 0.0010). Conclusion- There exists a positive correlation between the morphological features of retinal layers (External limiting membrane and photoreceptor layer IS/OS junction) on SD-OCT v/s best corrected visual acuity in diabetic macular oedema.
