[Ophthalmomyiasis externa acquired in Germany: case report and review of the literature].
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.


METHODS
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.


CONCLUSIONS
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.
