Thelazia

Thelazia

(thē-lā'zē-ă),
The eye worms, a genus of spiruroid nematodes that inhabit the lacrimal ducts and surface of the eyes of various domestic and wild animals, but rarely humans; a number of species have been reported from wild birds. Cyclic development occurs in muscoid flies; infective larvae emerge from the fly mouthparts while the fly is feeding on or near the eyes of the host.

Thelazia

a genus of spiruroid worms in the family Thelaziidae. They are all parasites of the lacrimal duct or conjunctival sac of mammals and birds. The larvae are deposited in the conjunctival sac by the intermediate host, Musca spp. flies. Causes thelaziasis.
