Abnormal Eyelashes / Trichiasis
Trichiasis is a common condition that occurs when the eyelashes grow inward, towards the eye, rubbing against the cornea, conjunctiva and the inner surface of the eyelid.
Causes of Trichiasis
The most common causes of trichiasis include the following:
- Chronic blepharitis
- Trauma
- Herpes zoster
- Epiblepharon
- Skin disorders
- Autoimmune conditions
Symptoms of Trichiasis
The typical symptoms of trichiasis are redness, irritation, tearing, the sensation of a foreign body in the eye and sensitivity to light. Eventually, the contact of the eyelashes on the eye may result in corneal abrasions and the formation of ulcers. A diagnosis of trichiasis is made upon an examination of the eye.
Treatment of Trichiasis
Treatment of trichiasis generally relies on the removal of the incorrectly positioned eyelashes. When there are relatively few lashes growing toward the eye, the doctor may pluck them out using forceps, but they often grow back the same way. For more permanent relief, electrolysis, radiofrequency, laser or cryotherapy treatments may be used to destroy the follicle so no regrowth can occur.
