Ten patients with Stargardt's disease and 14 with fundus flavimaculatus underwent thorough ophthalmic examinations, retinal photography, and, when possible, fluorescein angiography. Retinal function was also assessed by static and kinetic perimetry, the Farnsworth-Munsell 100-hue test, electro-oculography, and electroretinography. Visual acuity and color discrimination were reduced in all patients (mean visual acuity, 20/120; mean error score, 365). On electroretinography all patients had some significant abnormality of cone function and 24 eyes had abnormal rod function (mean Vmax, 298.3). Electrooculographic findings were abnormal in 24 eyes and borderline in ten others. These abnormalities were similar in both groups but more severe in fundus flavimaculatus. Stargardt's disease and fundus flavimaculatus did not co-exist in any family studied and the mean duration of disease was similar in both, indicating that Stargardt's disease did not progress to fundus flavimaculatus. Both the age of onset and duration significantly affected the severity of fundus flavimaculatus but neither had a significant effect on Stargardt's disease.
