  • Abstract
  • Look Inside

A 25-year-old female presented with severe visual loss in her right eye since 2 weeks before. The affected eye showed hyperemia of the optic disc and central scotoma. She was a heavy smoker and drinker. Her maternal grandfather and two uncles had reportedly advanced visual disturbances. Her left eye developed similar lesions 5 weeks later. Analysis of mitochondrial DNA showed point mutation at 11778, leading to the diagnosis of Leber's hereditary optic neuropathy (LHON) . Similar mitochondrial mutation was detected in her mother and younger brother. Both had full visual acuity. The brother showed bilateral central scotoma. The mother was diagnosed as carrier of LHON and the brother as its subclinical stage. These cases illustrate that LHON may involve females and that mitochonarial DNA analysis is useful in establishing the diangosis.
