[Taenia crassiceps in the anterior chamber of the human eye. A case report].

An otherwise healthy 15-year-old girl developed an iridocyclitis in her right eye. A contractable living parasite measuring two millimeter could be detected in the anterior chamber, the other parts of the eye remained uninvolved. The patient had close contact with the young dog of the family. By using a viscoelastic substance the parasite could be removed alive without any complications. The tapeworm was found to be too young for having developed the characteristic scolex. Western-immunoblotting gave indirect evidence for infection with Taenia crassiceps, a dog's tapeworm. During an observation period of two years no evidence for any other ocular or general Taenia crassiceps infestations could be found.
