Postoperative vision loss, a rare but devastating complication, has been reported after spine, cardiac, and head--neck surgeries. Its incidence following spine surgeries exceeds that after cardiothoracic surgeries. Various causes attributed to postoperative blindness include ischemic optic neuropathy, central or branch retinal artery occlusion, cortical blindness, and rarely external ocular injury. Other contributory factors described are microvascular diseases and intraoperative hemodynamic compromise. However, the exact association of these factors with postoperative blindness has not yet been confirmed. In this review, we describe causes, presentation, and treatment of postoperative blindness and also recommend practical guidelines to avoid this complication. The search strategies for this review included both search of electronic databases as well as manual search of relevant articles.
