Definition: 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.
