Abstract. Background:Leber hereditary optic neuropathy(LHON)has been known to show mutations of mitochondrial DNA(mtDNA). Mutations of mtDNA11778, 14484, and 3460 have been so far reported. Purpose:To report 3 cases of atypical optic neuropathy with varying mtDNA mutations. Cases:The present series comprised one female and 2 males. They were aged 47, 63 and 29 years respectively. Findings:Impaired visual acuity was noted one month before and, when seen, was 0.3 in either eye in the first case. Both eyes showed central scotoma and megalopapilla. She showed mutation at mtDNA15258. The second case had impaired vision 8 years before in the left eye and one year before in the right. Both eyes showed pale optic disc. Corrected visual acuity was 0.05 right and 0.02 left. The right eye reportedly showed disc edema and hyperfluorescence at the time of onset. He showed mutation at mtDNA9041. The third case had spina bifida, central scotoma and optic atrophy in both eyes. Visual acuity was 0.3 right and 0.6 left. He showed mutation at mtDNA15204. Conclusion:One female and 2 males showed atypical bilateral LHON and mtDNA mutations that have not been reported so far.
