Lebers hereditary optic neuropathy (LHON) is a mitochondrial inherited disease characterized by acute/subacute painless central visual loss. Except for optic atrophy, LHON patients are usually otherwise healthy. Occasionally, LHON is associated with neurological, cardiac, and skeletal changes. The same MRI pattern of abnormalities can be found in patients with LHON. It is sometimes associated with clinical signs of multiple sclerosis (Harding Syndrome). In this report, we present the case of a male patient with complaints of bilateral visual loss, who was diagnosed with Leber's hereditary optic neuropathy that was confirmed by the presence of a mutation at 3460G>A position. He was also diagnosed with comorbid multiple sclerosis which was confirmed by clinical findings and MR imaging.
