Perioperative Vision Loss in Cervical Spinal Surgery

STUDY DESIGN Retrospective multicenter case series. OBJECTIVE To assess the rate of perioperative vision loss following cervical spinal surgery. METHODS Medical records for 17 625 patients from 21 high-volume surgical centers from the AOSpine North America Clinical Research Network who received cervical spine surgery (levels from C2 to C7) between January 1, 2005, and December 31, 2011, inclusive, were reviewed to identify occurrences of vision loss following surgery. RESULTS Of the 17 625 patients in the registry, there were 13 946 patients assessed for the complication of blindness. There were 9591 cases that involved only anterior surgical approaches; the remaining 4355 cases were posterior and/or circumferential fusions. There were no cases of blindness or vision loss in the postoperative period reported during the sampling period. CONCLUSIONS Perioperative vision loss following cervical spinal surgery is exceedingly rare.
