What Is Trichiasis?
Trichiasis is a common eyelid problem. Eyelashes grow inwards toward the eye. The lashes rub against the cornea, the conjunctiva, and the inner surface of the eyelids. This irritates the eye.
What causes trichiasis?
Sometimes people get trichiasis and there is no known cause. Anyone can develop trichiasis. It is more common in adults. Some causes of trichiasis include:
Certain conditions increase your risk of developing trichiasis:
- Epiblepharon. This is congenital disorder. Loose skin around the eye forms a fold. This causes the lashes to assume a vertical position. This is mostly found in children of Asian ancestry.
- Herpes zoster eye disease.
- Trauma to the eye, such as burns.
- Chronic blepharitis. This is a common and ongoing condition. The eyelids become swollen. Oily particles and bacteria coat the lid margin near the base of the eyelashes.
- Trachoma. This is a severe eye infection found in developing nations.
- Rare disorders of the skin and mucous membranes. (Stevens-Johnson syndrome and cicatricial pemphigoid)
