부비동 내시경 수술 후 안와지판의 손상 없이 발생한 지연성 구후 혈종 1예

Retrobulbar hematoma is one of the major complications following endoscopic sinus surgery (ESS). Symptoms and physical findings include temporary blindness, ophthalmoplegia, mydriasis, ptosis, proptosis, and eyelid ecchymosis. Recently, we experienced a rare case of the delayed retrobulbar hematoma with intact lamina papyracea after ESS. Therefore, we present this case with an emphasis on the importance of prevention, identification and management of delayed retrobulbar hematoma. (J Clinical Otolaryngol 2014;25:240-243)
