    Unilateral Vision Loss without Ophthalmoplegia as a Rare Complication of Spinal Surgery
    (Medknow Publications & Media Pvt Ltd, 2017) Akpinar, Elif; Gurbuz, Mehmet Sabri; Bitirgen, Gulfidan; Okutan, Mehmet Ozerk
    Postoperative visual loss is an extremely rare complication of nonocular surgery. The most common causes are ischemic optic neuropathy, central retinal artery occlusion, and cerebral ischemia. Acute visual loss after spinal surgery is even rarer. The most important risk factors are long-lasting operations, massive bleedings, fluid overload, hypotension, hypothermia, coagulation disorders, direct trauma, embolism, long-term external ocular pressure, and anemia. Here, we present a case of a 54-year-old male who developed acute visual loss in his left eye after a lumbar instrumentation surgery and was diagnosed with retinal artery occlusion.
