Visual evoked response (VER) with pattern reversal recorded during the acute phase, initial therapy, and after recovery. (A) Day 1, visual acuity, right eye no light perception, left eye counting fingers 50 cm. No structured pattern was recorded from the right eye and prolonged latency was recorded over the left eye with a very low amplitude. These recordings indicate a non-functioning right optic pathway and severe damage to the left optic nerve. (B) Day 7, after 3 days of treatment, visual acuity was right eye hand movement and left eye 20/100. A definitive pattern is evident from both sides, however, latency is still prolonged corresponding to the recovery process of the optic pathways. (C) Seven weeks after methanol blindness visual acuity recovered in both eyes to 20/20. VER over the right eye demonstrates a residual prolonged latency whereas the VER pattern of the left eye returned to normal.
