Oestrus ovis, the sheep nasal botfly, is the most common cause of ophthalmomyiasis externa in North America. In the United States, most cases occur on Catalina Island. The symptoms of acute infestation with this organism resemble those of catarrhal conjunctivitis and the condition is considered to be self-limiting. Treatment consists of careful removal of the organisms and topical administration of corticosteroid and antibiotic drugs to relieve the symptoms and prevent bacterial contamination. We recently examined a 17-year-old woman who had visited Catalina Island and later developed acute O. ovis ophthalmomyiasis externa. To determine the incidence of chronic complications, we performed ophthalmic examinations on 15 Catalina Island residents who had had documented O. ovis ophthalmomyiasis externa before 1981. We found no evidence of persistent infestation or intraocular penetration by these organisms.
羊狂蝇（Oestrus ovis），即羊鼻狂蝇，是北美眼外肌蝇蛆病最常见的病因。在美国，大多数病例发生在卡特琳娜岛。感染这种生物体的急性症状类似于卡他性结膜炎，这种情况被认为是自限性的。治疗方法包括小心地清除这些生物体，并局部使用皮质类固醇和抗生素药物以缓解症状并防止细菌污染。我们最近检查了一名17岁的女性，她曾去过卡特琳娜岛，后来患上了急性羊狂蝇眼外肌蝇蛆病。为了确定慢性并发症的发生率，我们对15名在1981年之前有羊狂蝇眼外肌蝇蛆病记录的卡特琳娜岛居民进行了眼科检查。我们没有发现这些生物体持续感染或眼内侵入的证据。
