Adult onset foveomacular vitelliform dystrophy: a case report.
BACKGROUND
Pattern dystrophies of the retinal pigment epithelium, an arrangement of a pattern of dots, lines, or branches, are infrequent fundus abnormalities. Adult onset foveomacular vitelliform dystrophy (AOFVD) is considered a subtype of pattern dystrophy. Onset occurs during middle age, with an accumulation of yellow-gray macular deposits in the deeper retinal layers. Typically electro-oculograms are mildly subnormal or normal. Genetic studies suggest an autosomal dominant inheritance with variable penetrance.


METHODS
A case of a 56-year-old Hispanic women with a 1-month onset of "wavy moving vision" in both eyes is presented. Previous ocular and family history were unremarkable. Ophthalmoscopic examination revealed yellow circumscribed subretinal lesions of one-third to one-half disk diameter in the foveal centers of both eyes. Fluorescein angiography revealed a circumscribed area of mottled hyperfluorescence surrounding a central hypofluorescent spot. The patient was diagnosed with AOFVD. Examination of the patient's children revealed retinal pigment epithelial disturbances in the two oldest daughters, consistent with pattern dystrophies.


CONCLUSIONS
Our investigation supports an autosomal dominant inheritance pattern, as seen on pedigree. The presence of different pattern dystrophies within the same family suggests a common etiologic continuum.
