Case ReportsPosterior ischemic optic neuropathy: case report of a rare complication after general surgery.
Posterior ischemic optic neuropathy (PION) is a rare cause of bilateral severe and bilateral visual loss. Three mechanisms for posterior ischemic optic neuropathy are recognized: arteritic, non-arteritic, and peri- or postoperative. We report a case of bilateral postoperative posterior ischemic optic neuropathy. ⋯ Peri- and postoperative posterior ischemic optic neuropathy is a rare but devastating complication of surgery performed at distance from the visual pathways and its vascularization. Risk factors include: spine surgery, peri-operative hypotension, anemia, facial edema. Early recognition of posterior ischemic optic neuropathy and rapid correction of hypotension and/or anemia might improve outcome of posterior ischemic optic neuropathy, which usually is poor.
