Stargardt disease (STGD) is the most common type of hereditary macular dystrophy. It is characterized by decreased central vision, atrophy of the macula and underlying retinal pigment epithelium (RPE), and frequent presence of prominent flecks in the posterior pole of the retina. Histopathologically, eyes with STGD reveal abnormal accumulations of lipofuscin in the RPE. To date, mutations in four genes have been identified as causing STGD, including ABCA4, ELOVL4, PROM1, and CNGB3.
