Popis: Postoperative visual loss (POVL) is a rare but devastating complication after nonocular surgery. POVL can be caused by central retinal artery occlusion, ischemic optic neuropathy (ION), and cortical blindness. The most common cause of POVL related to prone spine surgery in adults is ION. Risk factors for the development of ION associated with spine surgery include male sex, Wilson frame use, obesity, a lower percentage of colloid administration, longer anesthetic duration, and a greater amount of estimated blood loss. One recent study using national data demonstrates that the incidence of POVL related to ION after spine surgery has decreased over the past decade and a half. This decreased incidence may be related to prior studies identifying risk factors and large-scale efforts to educate practitioners caring for these high-risk patients.
