About this study

The goal of this study is to update the incidence of perioperative vision loss from ischemic optic neuropathy, retinal vein or artery occlusion, and cortical blindness from all non-ocular general anesthesia surgery, including robotic surgery, that has been performed at Mayo Clinic from 2003-2012. The study will also aim to determine the visual acuity outcomes following perioperative vision loss.
