In many cases, removal of the affected eyelashes with forceps resolves the symptoms, although the problem often recurs in a few weeks when the eyelashes regrow. Severe cases may cause scarring of the cornea and lead to vision loss if untreated. Mild cases may not require treatment. Repeated cases of trachoma infection may cause trichiasis. [2]
The L3 larvae develop into adults in the eye or surrounding tissues of the host, where they may live for over one year. In the definitive host, Thelazia have been found in various tissues of the orbit (or socket) of the eye, including within the eyelids, in the tear glands , tear ducts , or the so-called "third eyelid" ( nictitating membrane ...
Chalazion* is a granuloma that forms in the eyelid due to blocked secretions from the meibomian gland. Inflammation of the eyelid may result. [64] Trichiasis in dogs is hair from the eyelid growing in the wrong direction and rubbing on the eye, causing irritation. It usually occurs at the lateral upper eyelid, especially in the English Cocker ...
A distichia is an eyelash that arises from an abnormal part of the eyelid. This abnormality, attributed to a genetic mutation, is known to affect dogs and humans. Distichiae usually exit from the duct of the meibomian gland at the eyelid margin. They are usually multiple, and sometimes more than one arises from a duct.
In many species, the third eyelid plays an essential role in vision by supplying oxygen and nutrients to the eye via tear production. [4] Normally, the gland can turn inside-out without detachment. [3] Cherry eye results from a defect in the retinaculum which is responsible for anchoring the gland to the periorbita.

Thelazia is a genus of nematode worms which parasitize the eyes and associated tissues of various bird and mammal hosts, including humans. [2] [3] They are often called "eyeworms", and infestation with Thelazia species is referred to as "thelaziasis" (occasionally spelled "thelaziosis").
