Abstract
To describe the optical coherence tomography OCT the standard shortwavelength fundus autofluorescence SWFAF and nearinfrared fundus autofluorescence NIRFAF and the microperimetric findings in a child with a unique unilateral lesion of the temporal macula previously called torpedo maculopathy A 4yearold female with torpedo maculopathy was evaluated with spectraldomain OCT SDOCT standard SWFAF excitation 488 nm emission 500 nm and NIRFAF excitation 787 nm emission 800 nm Microperimetry was performed to assess retinal sensitivity changes correlated to the macular lesion SDOCT 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 SWFAF resulted in normal fluorescence of the lesion except for a small hyperfluorescent area at the tail level NIRFAF 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 reevaluated 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
