A hereditary macular disorder, usually presenting between the ages of 30-60, characterized by a large area of atrophy in the centre of the macula and the loss or absence of photoreceptors, retinal pigment epithelium and choriocapillaris in this area, resulting in a progressive decrease in visual acuity.
