Fig. 6. Generalized choroidal dystrophy. This 65-year-old woman gradually developed enlarging, progressive areas of choroidal atrophy over a 20-year period. When initially seen, the abnormalities were confined to the peripapillary and macular region (A,B). In a recent examination, the generalized choroidal atrophy is vividly demonstrated on angiography (C–F).
