ResumoPurpose 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. Design Observational case report. Participant A 33-year-old woman who experienced visual loss in the immediate postoperative period after a lumbar spine fusion. Testing Serial visual field testing and fundus examinations, ERG. Results Bilateral PION was confirmed 2 months postoperatively with the development of bilateral optic disc pallor and a normal ERG. Conclusion 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.
