Leber?s Hereditary Optic Neuropathy

Leber’s Hereditary Optic Neuropathy (LHON) is a rare genetic disorder that causes progressive loss of vision due to damage to the cells of the optic nerve. It is caused by mutations in the mitochondrial genes, which are inherited from the mother. The most common symptom is sudden, painless vision loss, usually in both eyes. LHON can also cause color vision loss, visual field defects, and eye pain. Early diagnosis and treatment are essential to prevent further vision loss, and there is evidence that some treatments may be effective in slowing or stopping progression of the disease. LHON is a serious condition, but with early diagnosis and appropriate management, individuals may experience improved vision and decreased risk of additional vision loss.
