Stargardt disease is a progressive, inherited retinal disorder passed down genetically, typically emerging during childhood or young adulthood. This condition results from mutations in the ABCA4 gene, leading to an abnormal accumulation of a fatty, yellowish pigment called lipofuscin in the retinal cells. The buildup of lipofuscin in the macula (the region of the retina responsible for central vision) progressively impairs and damages photoreceptor cells, causing central vision loss over time. Key symptoms of the disease include reduced central visual acuity, impaired color vision, and night blindness.
