Anyone can develop trichiasis, although it is more common in adults. Trichiasis can be caused by an eye infection, inflammation (swelling) of the eyelid, autoimmune conditions and trauma.
Certain conditions increase your risk of developing trichiasis:
- Epiblepharon, a congenital disorder that occurs when loose skin around the eye form a fold that causes the lashes to assume a vertical position. Epiblepharon is most commonly found in children of Asian ancestry.
- Herpes zoster eye disease.
- Trauma to the eye, such as burns.
- Chronic blepharitis, a common and ongoing condition where the eyelids become inflamed (swollen), with oily particles and bacteria coating the eyelid margin near the base of the eyelashes.
- Trachoma, a severe eye infection that is commonly found in developing nations.
- Certain rare disorders of the skin and mucous membranes, including Stevens-Johnson syndrome and cicatricial pemphigoid.
