See text Thelazia is a genus of nematode worms which parasitize the eyes and associated tissues of various bird and mammal hosts, including humans.

This species is reported for the first time from an Andean Cock of the Rock, Rupicola peruviana (Passeriformes: Cotingidae), from a zoo in Lima, Peru.

Clinical signs of keratoconjunctivitis were resolved with the treatment of ivermectin, ciprofloxacin, and an epithelium regenerator, and the host is presently in good health.

This eyeworm commonly parasitizes in the tear ducts and conjunctival sac of its hosts, and appears as a creamy, thin-white thread measuring slightly over a half an inch in length.

Human infections caused by Thelazia callipaeda have also been reported in Japan, China, India, Taiwan, Burma, Thailand, Korea, Indonesia, Italy, Russia, and France.

The patient was diagnosed with parasitic infiltration of the left periocular tissues and a secondary bilateral papillary reaction of the upper and lower palpebral conjunctive.

Thelazia lacrymalis Equine thelaziosis is a neglected vector-borne parasitic disease in modern veterinary medicine, lacking recent reports.

It is transmitted by Musca autumnalis, and potentially other Muscidae species, by ingesting the lachrymal secretions of its equine host.

The distribution of both Thelazia lacrymalis and its intermediate hosts remains largely unknown throughout Europe, with most studies dating back 20 years.
