Fluorescein angiography of Stargardt’s disease

Stargardt disease (STGD), is the most common childhood recessively inherited macular dystrophy. The genetically based condition is due to mutations in the ABCA4 gene on chromosome 1 that encodes a retinal transported protein. The disease results from the accumulation of visual cycle kinetics-derived byproducts in the retinal pigmented epithelium (RPE) with secondary photoreceptor dysfunction and death. Fundus flecks, seen as small irregular hyperfluorescent lesions over the “dark-choroid” background, suggest a diagnosis of Stargardt disease.
