To report a case of bilateral posterior ischemic optic neuropathy (PION) in a healthy young patient after lumbar spine surgery which was initially diagnosed as functional visual loss.
Observational case report.
A 33-year-old woman who experienced visual loss in the immediate postoperative period after a lumbar spine fusion.
Serial visual field testing and fundus examinations, ERG.
Bilateral PION was confirmed 2 months postoperatively with the development of bilateral optic disc pallor and a normal ERG.
Young patients without vascular risk factors may develop bilateral PION after otherwise uncomplicated lumbar spine surgery. In subjects complaining of visual loss in the postoperative period who have a normal fundus and normal neuroimaging, a diagnosis of PION should be suspected, and close follow-up is warranted.
报告一例健康年轻患者在腰椎手术后发生双侧后部缺血性视神经病变（PION）的病例，该病例最初被诊断为功能性视力丧失。
观察性病例报告。
一名33岁女性，在腰椎融合术后即刻出现视力丧失。
系列视野检查、眼底检查、视网膜电图（ERG）。
术后2个月确诊为双侧PION，出现双侧视盘苍白，视网膜电图正常。
无血管危险因素的年轻患者在无并发症的腰椎手术后可能发生双侧PION。对于术后出现视力丧失且眼底和神经影像学检查正常的患者，应怀疑PION诊断，并进行密切随访。
