Leber hereditary optic neuropathy: respiratory chain dysfunction and degeneration of the optic nerve
Leber hereditary optic neuropathy (LHON) is an inherited form of bilateral optic atrophy in which the primary etiological event is a mutation in the mitochondrial genome. The optic neuropathy involves a loss of central vision due to degeneration of the retinal ganglion cells and optic nerve axons that subserve central vision. The primary mitochondrial mutation is necessary, but not sufficient, ...

BACKGROUND Leber hereditary optic neuropathy (LHON) is a cause of inherited blindness that typically presents with bilateral, painless, subacute visual failure in young adult males. Males are about four times more likely to be affected than females and 95% of LHON carriers become affected before the age of 50. Affected patients may have characteristic ocular fundal appearances and have evidence...
متن کاملLeber hereditary optic neuropathy: Mitochondrial mutations and degeneration of the optic nerve
The predominant manifestation of Leber hereditary optic neuropathy (LHON) is a sudden and usually severe bilateral loss of central vision, most often in the mid-20s, that is due to a degeneration of the ganglion cell layer and optic nerve. LHON is an inherited form of blindness in which a mutation in the mitochondrial genome (mtDNA) is the primary etiological event. More than 95% of the LHON pe...
متن کاملLeber hereditary optic neuropathy
Leber hereditary optic neuropathy is a maternally inherited bilateral optic neuropathy that typically affects teenage males with acute vision loss first in one eye and then the other within days or weeks. The etiology involves a point mutation in the mitochondrial DNA at 1 of 3 main loci: 11778, 14484, or 3460. There are some distinctive changes in the ocular fundus appearance at various stages...
