Abstract
PURPOSE: Multimodality image analysis of two cases of torpedo maculopathy. METHODS: Imaging with fundus photography, autofluorescence (AF), swept-source optical coherence tomography (OCT), en face OCT, and OCT angiography. RESULTS: The basal diameter of the torpedo lesions was 1 mm × 2 mm. One case had a satellite lesion. Autofluorescence indicated variable loss of signal. Swept-source OCT and en face OCT demonstrated fundus excavation, attenuation of nuclear layers and disruption of the outer plexiform layer, loss of photoreceptors and a subretinal cleft. In one case, Sattler layer appeared extended at the cleft. Optical coherence tomography angiography indicated loss of flow in deep retinal vessels and increased flow in choroidal vessels surrounding the cleft. CONCLUSION: Multimodal imaging findings of torpedo maculopathy include disruption of the deep retinal capillary network, expansion of Sattler layer, and increased signal around the subretinal cleft.
