Iohexol (300\u00a0mg I\/mL) from 50 to 60\u00a0mL (0.09-0.1\u00a0mL\/kg) were administered intrathecally. Six horses had focal facial motor seizures contralateral to the side of recumbency with expansion to generalized seizures in one horse. The seizure onset zone was determined to be the right parietal cortex based on electroencephalography. Absent menace response of the left eye with bilateral normal dazzle and pupillary light reflexes were supportive of cortical blindness (right occipital cortex) in 5 horses. Seizures were managed using short- (diazepam, 3 horses; midazolam, 2; both, 1) and long-term (phenobarbital\u00a0=\u00a02\/6) antiseizure medications with clinical resolution within 2-8\u00a0h post-myelogram.
