Plain-English summary
A 10-month-old thoroughbred colt suddenly became completely blind, but there were no other signs of neurological problems. After the horse passed away 3.5 months later, an examination revealed significant damage to the optic pathways, which are the nerves responsible for vision. The exact cause of this damage wasn't identified, but it might be related to exposure to a toxin. Unfortunately, the treatment options and outcomes for this condition were not discussed in the study.
Abstract
A 10-month-old thoroughbred colt developed sudden complete blindness; no other neurological abnormality was detected. At necropsy 3.5 months later lesions were confined to both optic pathways in which there was extensive degeneration of axons and myelin and gliosis. The cause of the optic lesion was not determined but the lesion may be a toxic neuropathy.
