Purpose: We report a case of complete visual recovery in methanol poisoning treated with hemodialysis, intravenous steroid, and folic acid.
Case summary: A 19-year-old woman visited the emergency room complaining of decreased vision 3 days after accidentally ingesting methanol. Her initial best corrected visual acuity (BCVA) were hand motion in right eye and 20/400 in left eye. No pupillary light reflex and apparent response of the visual evoked potential (VEP) test were observed. Treatment consisted of hemodialysis, and the intravenous administrations of methylprednisolone and folic acid.
Conclusions: Fifteen days after treatment, BCVA was 20/400 (right eye) and 20/50 (left eye), and slight P100 delay with normalized VEP amplitude was observed on both eyes. Two months after treatment, BCVA of both eyes was 20/20. VEP showed normal amplitude with sustained mild P100 delay. One year after treatment, BCVA of both eyes was maintained and there was no evidence of optic atrophy.
