Foveomacular Vitelliform Dystrophy, Adult Type

Vitelliform macular dystrophy, adult type, is a type of pattern dystrophies of the pigment epithelium characterized by autosomal daminant inheritance, mid-life onset and small, round or oval, yellow deposits located at the level of the pigment epithelium. The authors report a case of this dystrophy which showed small yellow round lesion measuring 1/4-1/3 D.D. within the macula, normal electroretinogram, subnormal electrooculogram light-peak/dark-traugh ratio. typical irregular ring-like transmitted fluorescence surrounding the central non-fluorescent Iesion and leakage from perifoveal capillaries on fluorescent angiogram.
