We examined 4 eyes in 4 patients of macular degeneration by optical coherence tomography (OCT). The series comprised one eye of Alport syndrome and 3 eyes of cone or cone-rod dystrophy. In Alport syndrome, OCT showed thinning of sensory retina and high-reflective layer corresponding to retinal pigment epithelium and choriocapillaris. In 3 eyes of cone or cone-rod dystrophy, OCT showed absence of low-reflective layer corresponding to the photoreceptors. The foveal thickness in the 4 eyes ranged from 25 to 73μm, average 56.0± 21.4μm. It averaged 136.3±12.3μm in normal eyes. The difference was significant (p<0.05). The diameter of macular depression averaged 1,452.8±149.3μm in the 4 eyes and 1,258.5±47.1μm in normal eyes. The difference was significant (p<0.05).
