Abstract

To describe the optical coherence tomography (OCT), the standard short-wavelength fundus autofluorescence (SW-FAF) and near-infrared fundus autofluorescence (NIR-FAF), and the microperimetric findings in a child with a unique unilateral lesion of the temporal macula previously called torpedo maculopathy. A 4-year-old female with torpedo maculopathy was evaluated with spectral-domain OCT (SD-OCT), standard SW-FAF (excitation 488 nm, emission >500 nm) and NIR-FAF (excitation 787 nm, emission >800 nm). Microperimetry was performed to assess retinal sensitivity changes correlated to the macular lesion. SD-OCT showed an abnormally thin retinal pigment epithelium signal and an increased signal transmission in the choroid corresponding to the torpedo lesion with no neuroretinal changes. SW-FAF resulted in normal fluorescence of the lesion except for a small hyperfluorescent area at the tail level. NIR-FAF showed hypofluorescence corresponding to the lesion. Macular microperimetry showed reduced retinal sensitivity along the pigmented margins of the lesion with normal values over the lesion. The patient was re-evaluated 12 months later and no change was documented with all diagnostic techniques. This case supports a congenital defect of retinal pigment epithelium. The absence of both functional changes at lesion level and neuroretinal changes at OCT may depend on the very early detection of this lesion.
