To report a case of non-arteritic anterior ischemic optic neuropathy (NAION) observed immediately after uncomplicated strabismus surgery performed under general anesthesia.
A 61-year-old woman underwent an uncomplicated strabismus surgery of her right eye under general anesthesia. Preoperatively visual acuity (VA) was LogMAR 0.18 in both eyes.
Retrospective, observational case report and literature review.
Two days following surgery, patient presented with painless visual loss. VA was No Perception of Light (NPL). Fundoscopy revealed right optic disc swelling and relative afferent pupillary defect. Perioperatively patient experienced 2 hypotensive episodes. She was evaluated for alternative etiologies of her optic neuropathy, with negative results. She was found to have mild hypercholesterolemia, which was not known prior to surgery. After 2 months she developed optic atrophy in the affected eye and the visual acuity did not recover.
To our knowledge, this is the first documented case of non-arteritic anterior ischemic optic neuropathy occurring immediately after strabismus surgery.
报告1例在全身麻醉下进行简单斜视手术后立即出现的非动脉炎性前部缺血性视神经病变（NAION）病例。
一名61岁女性在全身麻醉下接受了右眼简单斜视手术。术前双眼视力（VA）为LogMAR 0.18。
回顾性观察病例报告及文献复习。
术后两天，患者出现无痛性视力丧失。视力为无光感（NPL）。眼底检查显示右侧视盘肿胀及相对性传入性瞳孔障碍。围手术期患者经历了2次低血压发作。对其视神经病变的其他病因进行评估，结果为阴性。发现她患有轻度高胆固醇血症，手术前并不知晓。2个月后，患眼出现视神经萎缩，视力未恢复。
据我们所知，这是第一例有记录的斜视手术后立即发生非动脉炎性前部缺血性视神经病变的病例。
