Transient visual acuity loss after spine surgery in the prone position: a case report and literature review.

Visual loss after spine surgery in the prone position is a disastrous postoperative complication because it is almost irreversible. Additionally, the optimal treatments and recommended professional guidelines for visual loss after spine surgery are deficient. A 43-year-old man developed visual loss after spine surgery in the prone position. Immediate ophthalmic consultation confirmed central retinal artery occlusion. Therefore, combined therapies were administered, including neurotrophy, anticoagulation, vasodilation, and adequate fluid infusion, followed by hyperbaric oxygen treatment. After active treatment, his visual acuity gradually recovered from 5 hours postoperatively and continued to improve thereafter. We reviewed the literature on postoperative visual loss with a focus on spine surgery in the prone position. Because the etiology of this complication is complex and has few effective treatments, the best method for its avoidance is to pay close attention to preventing it during surgery.
