Leber's hereditary optic neuropathy is a maternally inherited disorder characterized by acute or subacute loss of central vision leading to severe optic atrophy. It is caused by mutations in the mitochondrial genome. Primary mutations are located at nucleotide positions 3460, 11778 and 14484 in genes encoding subunits of complex I of the respiratory chain. The occurrence of a demyelinating disease such as multiple sclerosis has been reported mainly in females with the 11778 mutation. We report a patient with Leber's hereditary optic neuropathy, kyphosis and white matter lesions in association with the 3460 mtDNA mutation. It is suggested that multiple sclerosis-like illness and deformities of the vertebral column may be associated pathogenically with Leber's hereditary optic neuropathy.
