Introduction
Methanol is a toxic alcohol which is metabolized in the body to formic acid and causes severe intoxication. Methanol poisoning is very dangerous because it can cause severe visual impairment (including irreversible bilateral blindness), metabolic acidosis, permanent neurological dysfunction and even death 1. Irreversible visual loss may occur within hours to days after ingestion. Treatment regimens are aimed at controlling acid-base balance, removing the toxic agent by hemodialysis, or using ethanol solution as a competitive drug 2. In this study we report a case of unilateral visual loss due to methanol intoxication.
