  • Abstract
  • Look Inside

A 13-year-old boy presented with acute visual impairment since 2 months before. His corrected visual acuity was 0.03 right and 0.02 left. Routine ophthalmological examinations,including fluorescein angiography,were inconclusive. Goldmann perimetry showed central scotoma in both eyes. Magnetic resonance imaging(MRI)showed findigs suggestive of retrobulbar neuritis. Systemic pulsed corticosteroid was followed by improvement of visual acuity to 0.5 in either eye. The visual field remained the same for 6 months until present. He was found to have mitochondrial DNA 3460 mutation,which led to the definitive diagnosis of Leber hereditary optic neuropathy(LHON). An overwhelming majority of Japanese patients of LHON are known to have 11778 mutation. Difference in the site of gene mutation may have been the reason for the relatively benign course in this patient.
