Abstract: | 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. CASE REPORT: 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. CONCLUSION: 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. |
