Anesthesiology

Perioperative ischemic optic neuropathy (ION) can cause visual loss during spinal surgery. In this issue of Anesthesiology, Rubin et al. employ a large nationwide administrative hospital database to assess trends and risk factors for ION and demonstrate that perioperative ION in spinal fusion is decreasing. In an accompanying Editorial View, Todd discusses why the rate of ION might be on the decline.
