• Anterior ischemic optic neuropathy is an uncommon and devastating event that can result in unilateral or bilateral blindness. It has been reported as a complication of ophthalmologic or general surgical and cardiothoracic procedures as well as a spontaneous event in severe systemic disease. Aggravating intraoperative factors include anemia, hemorrhage, hypotension, preexisting small-vessel disease, and increased intraocular pressure. We present a case of anterior ischemic optic neuropathy as a complication in a 48-year-old man undergoing extensive resection of recurrent carcinoma of the head and neck. Possible contributing risk factors in our patient include preexisting hypertension, intraoperative blood loss, previous radical neck dissection with venous compromise, intraoperative head and neck edema, and the use of tightly adherent plastic bubble-type intraoperative eye protection. The possible pathogenesis of this devastating complication and recommendations for prevention and management of anterior ischemic optic neuropathy are described.
