Abstract:
This article presents the case of a 72-year-old male patient who suffered severe trauma of the spinal column. The patient developed persistent, bilateral, complete blindness after prolonged emergency neurosurgical treatment in a prone position. A bilateral surgical posterior ischemic optic neuropathy (PION) was diagnosed, which is a rare but severe complication of prolonged non-ocular surgery with circulatory stress. The massive, mostly bilateral, irreversible visual loss up to complete blindness leads to severe and permanent impairment of affected patients.
