Infestation with larvae (maggots) is known as myiasis. Ophthalmomyiasis externa refers specifically to infestation that involves the lids and conjunctiva in man. Ophthalmomyiasis which originates from Germany is unusual, because the vector of the Oestrus ovis larvae is most prevalent in the warm climate of Mediterranean countries. The sheep nasal botfly (Oestrus ovis sp.) is responsible for most cases of external ophthalmomyiasis. This case report gives a detailed description of the larvae, their life cycle and an overview of infestations in Germany as well as the therapy of ophthalmomyiasis.
At the end of August 1999, a 28-year-old man attended the outpatient department of Giessen University Eye Clinic with a foreign body sensation in his left eye. He reported that something hit his left eye while he was climbing on his motorbike in the early evening hours. Shortly afterwards he had a foreign body sensation in his left eye. On history taking he reported no other ophthalmologic problems in the past. Slitlamp biomicroscopy revealed white, vivid, approximately 1.5-mm-long, light-sensitive maggots on the conjunctiva and under the upper lid. These were removed mechanically and the conjunctiva rinsed with saline. Local therapy was not applied.
Infestation with larvae of O. ovis has to be considered not only in tourists from Mediterranean countries, but also in Germany in the late summer.
幼虫（蛆虫）感染被称为蝇蛆病。眼外蝇蛆病特指人类眼睑和结膜的感染。源自德国的眼蝇蛆病并不常见，因为羊狂蝇幼虫的传播媒介在地中海国家温暖气候中最为普遍。羊鼻狂蝇（Oestrus ovis sp.）是大多数眼外蝇蛆病病例的病因。本病例报告详细描述了幼虫、其生命周期，概述了德国的感染情况以及眼蝇蛆病的治疗方法。
1999年8月底，一名28岁男性因左眼有异物感前往吉森大学眼科门诊就诊。他报告说，傍晚时分骑摩托车时，有东西碰到了他的左眼。此后不久，他左眼就有了异物感。在病史询问中，他报告过去没有其他眼科问题。裂隙灯生物显微镜检查发现结膜和上睑下有白色、鲜活、约1.5毫米长、对光敏感的蛆虫。这些蛆虫被机械清除，结膜用盐水冲洗。未进行局部治疗。
不仅来自地中海国家的游客，而且在德国夏末，都必须考虑羊狂蝇幼虫感染的情况。
