[Leber's optic neuropathy presenting as an alcohol- and tobacco-related optic neuropathy]

Abstract

The authors report a case of a 70-year-old man presenting a recent unilateral decrease in visual acuity, appearing in a context of alcohol and tobacco intoxication. Diagnosis of Leber's optic neuropathy was evoked after elimination of other causes of a visual acuity decrease such as giant cell arteritis and compressive or inflammatory optic neuropathy. The authors emphasize that Leber's optic neuropathy must be evoked in a recent decrease in visual acuity, even if it appears in an unusual context.
