A 60-year-old @entity1 with a history of chronic @entity988 and @entity286 use presented with the complaint of a @entity227 . She lost vision first in the left eye then in the right eye. She admitted consuming at least one 16 ounce bottle of over the counter mouthwash daily and denied consumption of any other @entity4313 , @entity1042 , or antifreeze. She stated that her vision had been continuing to deteriorate in both eyes. Her best-corrected visual acuity was 4/200 in each eye. Color vision was nil in each eye. Her pupils were sluggish bilaterally, and her optic discs were flat and hyperemic with @entity548 . Her visual fields revealed @entity1019 bilaterally. The magnetic resonance imaging of the brain and lumbar puncture were within normal limits. Antinuclear antibody, human leukocyte antigen-B27 genotyping, and B12 were normal; serum @entity9138 was low. While continuing to ingest mouthwash, her vision decreased to count fingers at 2 feet, and maculopapillary bundle pallor developed. She was started on @entity1501 and @entity9138 supplementation. Once she discontinued mouthwash, her vision improved to 20/400 bilaterally, and her @entity1019 improved. This case demonstrates an @entity167 -induced @entity1781 from mouthwash ingestion with some visual recovery after discontinuation of the offending agent.

XXXX : An unusual cause.
