Stargardt's disease and fundus flavimaculatus.
A study of 67 patients with a diagnosis of Stargardt's disease (juvenile macular degeneration) or fundus flavimaculatus showed that, apart from the ophthalmoscopic appearance, there is no clear distinction between these two disorders. The disease is an autosomal recessive macular degeneration that is bilateral and symmetrical in appearance, with diminished central vision as the hallmark symptom. The onset of symptoms usually occurred in the first or second decade, but a substantial number of patients were asymptomatic until the fourth or fifth decade. Psychophysical and electrophysiologic tests indicated that this is a localized and not a generalized retinal dystrophy. While the initial vision in the better eye was 6/12 (20/40) or better in one third of the patients, follow-up studies showed progression to levels between 6/30 (20/100) and 6/60 (20/400).
