Intraoperative anaphylaxis to bacitracin during scleral buckle surgery

A 63-year-old man with a history of retinal detachment in the right eye repaired by scleral buckle presented with decreased peripheral vision in the left eye and was found to have a macula-sparing retinal detachment in the left eye, for which urgent repair by scleral buckle was recommended. The patient did not take any routine outpatient medications. Preoperative evaluation revealed no history of anesthetic complications, and he denied any drug allergies. He did not receive any preoperative prophylactic antibiotics.
