Progressive Changes in a Torpedo Maculopathy Lesion Over a 6-Year Period

To report the longitudinal changes on optical coherence tomography (OCT) in a patient with torpedo maculopathy (TM).

Retrospective observational study.

A 37-year-old male, without any ocular symptoms, on dilated fundus examination showed a characteristic torpedo-shaped, flat, horizontally oriented, ovoid-shaped, hypopigmented chorioretinal lesion, temporal to the foveal center. At the most recent visit, after 6 years, the lesion exhibited changes on OCT, including the collapse of the subretinal cleft, the thinning of the retinal pigment epithelium (RPE) layer and inner choroidal layers, and the increased visibility of the underlying choroid and inner retinal excavation. The fundus autofluorescence demonstrated an increase in hypoautofluorescence in the center of the torpedo lesion, which was surrounded by a hyperautofluorescent boundary.

This appears to be the first report of longitudinal changes in a classic case of TM, demonstrating changes in the RPE, inner choroidal, and outer retinal layers over time.
