Abstract

We report a 52-year-old man with methanol intoxication who showed optic nerve damage as assessed by magnetic resonance imaging (MRI). He was admitted to the hospital with blurred vision after the consumption of alcohol (600-700 ml of cologne). He was treated with intravenous ethanol, NaHCO3 and hemodialysis. On admission, a brain and orbital MRI was performed. Bilateral mild contrast enhancement was detected on the contrast-enhanced images in the retrobulbar segment of the optic nerves (RBONs). Also, diffusion-weighted images showed restricted diffusion in the RBONs. Diagnosis was considered as methanol-induced optic neuropathy based on the MRI findings of the optic nerves.
