Bull's-eye macular dystrophy associated with peripheral involvement.

Although central vision in Stargardt's disease is impaired relatively early, peripheral function is usually little affected and patients do not lose all vision. We report 4 patients with bull's-eye macular dystrophy that is indistinguishable from Stargardt's disease/fundus flavimaculatus, but with very depressed peripheral retinal function. One patient had bull's-eye maculopathy with a dark choroid on the fluorescein angiogram with a normal peripheral fundus and good retinal function initially. Sixteen years later, however, peripheral bone corpuscle pigmentation and optic disc atrophy developed and the electroretinogram became nonrecordable. Three patients from another family also had peripheral pigment degeneration besides macular degeneration. These cases may represent a rare combination of Stargardt's disease and retinitis pigmentosa. However, there was no clinical sign or even suggestion of retinitis pigmentosa at the initial examination in 1 patient. The mode of inheritance in 3 of our patients is probably autosomal recessive.
