What Is Trichiasis?
Trichiasis, in a layman’s terminology, refers to the condition of the inward growth of the eyelashes. Such inward growth of eyelashes tend to irritate the cornea or conjunctiva, thereby scarring the cornea and may lead to vision loss. Trichiasis also refers to the condition of hair on the nasal fold irritating the eye.
What causes Trichiasis
- Injury to the eyelid can result in Trichiasis. Such injury might tend to heal in a misaligned position that leads to the ingrowth of eyelashes that, in turn, rub the cornea.
- Entropion is defined as the rotation of the eyelash follicle causing the lash to grow inwards, resulting in abrasion of the cornea.
- Blepharitis, a chronic inflammation of eyelids, results in scarring of the eyelid edge that, in turn, results in Trichiasis.
- One of the rare conditions, which causes Trichiasis is known as distichiasis in which an extra row of eyelashes forms and such eyelashes grow inwards leading to rubbing the eyeball.
What are the signs and symptoms of Trichiasis
- Eye redness.
- Eye watering.
- Irritating sensation of the eyeball
How to treat Trichiasis
- A standard and longstanding treatment for trichiasis is surgical removal.
- Epilation using a forceps is effective but provides temporary relief only till the re-growth of the eyelash.
- Artificial Tears/Ointments may reduce the irritating sensation in the eye temporarily.
- Azithromycin has shown a partial response to reduce recurrence rates of postsurgical trichiasis.
- Electrolysis can be utilized for permanent removal of the offending eyelashes, but there is a high recurrence rate to the extent of 50%.
- Cryotherapy has shown to have the highest cure rate, but comes with associated complications like lid swelling, skin pigmentation, and notching.
- Argon laser for trichiasis has given reasonable success rate, and is currently most used surgical treatment.
