Objective: The aim of this study is to compare the sensitivities of chart 1 and chart 7 of the Amsler grid in early detection of metamorphopsia suggestive of diabetic macular edema. Design: It was a randomized, prospective, analytical study. Eighty patients were divided into two equal groups-A and B. Group A patients were given Amsler chart 1 and group B patients given Amsler chart 7.Regular 3 monthly follow up was done for 2 years with Optical Coherence Tomography (OCT) to detect DME on every follow up.
