Clinical information Vitelliform macular dystrophy (Best macular dystrophy) is a genetic eye disorder characterized by a progressive vision loss. This disease affects the retina, in particular macula, which is responsible for the central vision. In most patients with Best macular dystrophy, a fatty yellowish pigment (lipofuscin) is deposited in the cells underlying macula. There has been two forms of vitelliform macular dystrophy described in the literature. The early-onset form (known as Best disease) usually appears in childhood; the onset of symptoms and the severity are variable. The adult-onset form begins later, usually in mid-adulthood and leads to a gradual vision loss slowly progressing over time.
