Microvascular retinal changes in Torpedo Maculopathy

Abstract

We are reporting a case of torpedo maculopathy (TM) over a long term follow up with the aid of multimodal imaging of Optical coherence tomography (OCT), Fundus Autofluorescence, En Face OCT, and recent OCT angiography (OCTA) findings. An asymptomatic 18 years old female was clinically found to be having a whitish spindle shaped lesion in the right eye with classic findings of TM. OCT imaging at baseline and at 2 and 4 years follow up did not reveal any change in the retinal structures. A focal excavation of the choroid along with a small subretinal cleft was also seen. Fundus autofluorescence imaging exhibits a central hypofluorescence along with a hyperfluorescent border corresponding to the lesion. OCTA segmentation of the choriocapillaris vasculature showed increased density of the choroidal vasculature suggestive of its role in the pathogenesis of this lesion. Enigma behind the pathogenesis of this rare lesion is still unsolved. Recently introduced imaging techniques can help us understand this lesion and its pathogenesis in detail.
