Fourth cranial nerve palsy following spinal anesthesia. A case report.

Fourth nerve palsy has been rarely seen following lumbar puncture, myelogram, or spinal anesthesia. We report a case of 4th nerve and 6th nerve palsies following spinal anesthesia. The 4th nerve palsy was best detected by using a Maddox rod. If all 6th nerve palsies occurring after spinal anesthesia were examined with a Maddox rod, more cyclovertical palsies might be discovered.
