General Discussion
Leber hereditary optic neuropathy (LHON) is a rare inherited disorder of the eye that is characterized by the relatively slow, painless, progressive loss of vision. This disorder can initially affect one eye or both, but both eyes are usually affected within six months. In most cases, visual loss is permanent. LHON is a genetic disorder that occurs as the result of a mutation in the mitochondrial DNA that is inherited from the mother or arises as a new sporadic mitochondrial DNA mutation.
