[Bilateral optic neuropathy from methanol intoxication. A case report].

Methanol poisoning generally occurs after voluntary or accidental ingestion and can be responsible for blindness by optic neuropathy. We describe two cases of methanol poisoning who developed bilateral optic atrophy despite a treatment combining corticosteroids and vitamin B. Through these observations we recall the physiopathology as well as the clinical and therapeutic aspects of this type of intoxication.
