摘要

Literature review using PubMed, relating ophthalmologic complications in spinal surgery. Ischemic optic neuropathy (ION), central retinal artery occlusion (CRAO) and cortical blindness (CB) constitute the majority of cases. These are rare complications and have a poor prognosis. Post-operative visual loss (POVL) occurs most often in surgical procedures performed in the prone position. Being male, anemia, blood transfusion, and prolonged surgery time are related to ION, while malposition and direct compression of the eyeball are related to the development of CRAO. Level of Evidence III; Systematic review b of level III studies.
