Circumstances of onset and family history were obtained and ophthalmoscopy, fundus fluorescein angiography, visual field and visual evoked potential were performed on all 38 patients. Result: 30 In 38 patients (78.95 % ) harbor nt11778 mutation, including 28 male (93.33%) and 2 female (6.67%). The ratio of affected male to female is 14: 1. Patients harboring nt11778 mutation display typical clinical nanifestations.Ccnclusion: Identification of one of the three LHON specifically associated ntDNA mutations is essential to confirm the diagnosis.
