Coats’ disease is typically seen in childhood and less commonly among adults. The Adult onset form is manifested by various findings typical of Coats’ disease which include the unilateral nature of the disease, male predominance, vascular telangiectasis, lipid exudation, macular edema, and areas of capillary nonperfusion with adjacent webs of filigree like capillaries. We hereby report a case of a 55 year old male who presented with a visual acuity of 6/6 in both the eyes. Fundus examination revealed localised superotemporal, midperipheral telangiectatic vessles surrounded by hard exudates with exudative retinal detachment in the left eye. Fluorescein angiography showed leakage from the telangiectatic vessels along with capillary non perfusion areas. A provisional diagnosis of Coats’ disease was made. The lesion responded well to focal laser photocoagulation.
