Case 1. A Color fundus photography demonstrates a horizontally oval, hypopigmented, torpedo-shaped lesion in the temporal macula. Serial photography documents apparent stability of the torpedo lesion over the 10 year observation period. B Fundus autofluorescence demonstrates typical features of TM, including hypoautoflurescence of the lesion interior and hyperautofluorescence of the lesion margins. There is no apparent change in the signal pattern over the observation period. C Spectral domain optical coherence tomography (OCT). Each image represents a horizontal B-scan through approximately the same location in the middle of the torpedo lesion. Because the examinations were performed on different instruments at each time period, the scans are not of the identical fundus location. Nonetheless, they are as close to the same fundus location as possible. Comparison of the images suggests that the lesion has remained relatively stable over the observation period. D Microperimetry was only performed at baseline and the 5 year follow-up visit. No change in the size or depth of the scotoma produced by the deeply excavated temporal aspect of the torpedo lesion was detected. E Standard automated perimetry was normal at each visit
