Methanol ingestion can cause sudden blindness. This case study shows visual function improved despite delayed treatment, highlighting optic nerve damage and recovery in methanol poisoning.

Area of Science:

Toxicology
Ophthalmology
Neuroscience

Background:

Methanol is a toxic industrial solvent and antifreeze ingredient.
Accidental ingestion can lead to severe visual impairment or death.
Prompt medical intervention is crucial for managing methanol poisoning.

Observation:

A young woman experienced sudden visual failure after consuming a methanol-fortified beverage.
Initial examination revealed optic disc hyperemia and venous engorgement.
Despite delayed treatment, her visual function showed improvement.

Findings:

The patient developed optic disc atrophy and glaucomatous-like cupping.
The case illustrates the potential for visual recovery in methanol poisoning.
Discusses the etiology of visual failure and therapeutic guidelines.
