Acute methanol ingestion can cause characteristic ocular damage, together with widespread electrophysiological dysfunction. The data presented suggest that methanol affects the photoreceptors, Muller cells and the retrolaminar portion of the optic nerve.

The results are very different to those reported by other centres. Most notably, a much higher incidence of infection by Corynebacterium spp. and Moraxella spp. and a lower incidence of Pseudomonas aeruginosa was found. In this centre it appears appropriate to initially treat patients with Gram-positive organisms with chloramphenicol and patients with Gram-negative organisms with ciprofloxacin. Patients with a negative Gram stain should be treated with alternating chloramphenicol and ciprofloxacin while awaiting culture results.
