title: Vision Loss due to Central Retinal Artery Occlusion Following Embolization in a Case of a Giant Juvenile Nasopharyngeal Angiofibroma.
abstract: Juvenile nasopharyngeal angiofibroma (JNA) is a benign, vascular, and locally aggressive tumor that arises in the nasal cavity, extending into the nasopharynx and often in to the orbit. It may rarely present to the ophthalmologist with proptosis and optic neuropathy. Preoperative embolization of JNA is done before surgical resection. In this communication, the authors report a rare occurrence of ipsilateral central retinal artery occlusion (CRAO) following embolization with polyvinyl alcohol in a 13-year-old boy with right-sided JNA. Retrospective review of the angiograms pointed out to a suspicious communication between the external carotid artery and the ophthalmic vessels. Pre-embolization detailed study of the angiograms is necessary to avoid such devastating complications. Although rare, vision loss is a possible complication arising from embolization of nasopharyngeal and intracranial tumors, and all patients undergoing these procedures should be informed of the risk of visual loss because it has a lasting impact on the quality of life.
