A 69-year-old man presented with a rare case of retinal artery embolization, which occurred as a complication of carotid angioplasty and carotid artery stenting performed for recurrent cerebral infarction. Magnetic resonance imaging and angiography showed right internal carotid artery stenosis with ulceration. Carotid angioplasty and carotid artery stenting were performed using the distal protection system with the PercuSurge GuardWire. However, just after dilation, the patient complained of ocular pain and blurred vision on the right, which was subsequently diagnosed as retinal artery embolization. Heparin was given for 15 hours after stenting, and aspirin and ticlopidine medication were continued. The patient received hyperbaric oxygen therapy for 1 week. The patient's blurred vision gradually improved, but visual field defect remained. Debris was probably flushed into the external carotid artery, and passed through an anastomosis into the ophthalmic artery, resulting in retinal artery embolization.
