Abstract：
Perioperative vision loss (POVL) is a devastating surgical complication that impacts both the recovery from surgery and quality of life, most commonly occurring after spine surgery. With rates of spine surgery dramatically increasing, the prevalence of POVL will increase proportionately. This scoping review aims to aggregate the literature pertinent to POVL in spine surgery and consolidate recommendations and preventative measures to reduce the risk of POVL. There are several causes of POVL, and the main contribution following spine surgery is ischemic optic neuropathy (ION). Vision loss often manifests immediately following surgery and is irreversible and severe. Diffusion weighted imaging has recently surfaced as a diagnostic tool to identify ION. There are no effective treatments; therefore, risk stratification for counseling and prevention are vital. Patients undergoing prone surgery of long duration and/or with significant expected blood loss are at greatest risk. Future research is necessary to develop effective treatments.
摘要：
围手术期视力丧失（POVL）是一种破坏性的手术并发症，影响手术恢复和生活质量，最常见于脊柱手术后。随着脊柱手术率的急剧增加，POVL的患病率会成比例增加.本范围综述旨在汇总脊柱外科中与POVL相关的文献，并巩固降低POVL风险的建议和预防措施。POVL有几个原因，脊柱手术后的主要贡献是缺血性视神经病变（ION）。视力丧失通常在手术后立即表现出来,并且是不可逆的和严重的。扩散加权成像最近已成为识别ION的诊断工具。没有有效的治疗方法；因此，风险分层对咨询和预防至关重要。接受长时间俯卧手术和/或预期大量失血的患者风险最大。未来的研究对于开发有效的治疗方法是必要的。
