Abstract

A 61-year-old gentleman with BCVA 6/6 N6 came for routine eye check-up. Fundus examination revealed an oval shaped hypopigmented lesion inferotemporal to fovea. The lesion had well defined borders with a frayed tail pointing away from fovea.

Torpedo maculopathy also called congenital hypomelanotic freckle is a rare retinal pigment epithelial anomaly characteristically seen along horizontal raphe temporal to fovea. They are mostly asymptomatic and hence undetected. Hypotheses for etiology ranging from malformed horizontal raphe to congenital outpouchings of choroid were suggested. OCT appearances are of two types –attenuation of outer retina alone or with associated outer retinal cavitation. Based on hypo-reflectivity in choroidal vascular segments seen in OCT angiography of few cases, a pathology of choroid circulation is also suggested. Regular follow up helps in early detection of plausible complications like neurosensory detachment or choroid neovascularisation
