Disease at a Glance

Dominant optic atrophy (DOA) is an inherited optic nerve disorder characterized by degeneration of the optic nerves. It typically starts during the first decade of life. Affected people usually develop moderate visual loss and color vision defects. The severity varies and visual acuity can range from normal to legal blindness. About 20% of people with DOA have non-ocular features, such as sensorineural hearing loss; myopathy; peripheral neuropathy; multiple sclerosis-like illness; and spastic paraplegia (impaired function of the legs). These cases may be referred to as 'DOA plus.' DOA is inherited in an autosomal dominant manner and may be caused by a genetic change in any of several genes, some of which have not been identified.
