Novel use of idebenone in Leber's hereditary optic neuropathy in Hong Kong.

ABSTRACT

We report a case of a young Chinese male presenting with sequential, painless, bilateral visual loss in Hong Kong. He was diagnosed to have Leber's hereditary optic neuropathy with genetic workup showing G11778A mutation with over 80% heteroplasmy. He was started on idebenone treatment 11 months after onset of the binocular disease. To our best knowledge, this is the first case of Leber's hereditary optic neuropathy treated with idebenone in Hong Kong. The recent evidence of the diagnosis and treatment of this devastating disease is reviewed.
