Trichiasis

What Is Trichiasis?

Trichiasis is the name of the condition that occurs when eyelashes start growing inwards toward the eye instead of out and away from it. This causes the lashes to rub against the eye and the inner part of the eyelid, which leads to eye irritation and the uncomfortable feeling that something is constantly stuck in the eye.

If the condition persists for a long period of time without treatment, it can lead to eye infections, scarring on the cornea, or even damage to your vision in severe cases. To prevent long-term damage to the eye and your vision, schedule an appointment with your eye doctor if symptoms appear.

Causes of Trichiasis

There are many potential causes for trichiasis. Often, it is the result of another eye condition or trauma to the eye.

Eye Infection – Various types of eye infection can lead to trichiasis. It’s common for blepharitis, inflammation of the eyelids, to cause trichiasis because it can irritate the base of the eyelashes and cause misdirected growth.

Eye Trauma – Injury to the eye, especially burns, can disrupt the normal growth of the eyelashes and cause trichiasis.

Herpes Zoster Ophthalmicus – This condition, more commonly known as shingles, causes a painful rash on the forehead and eyelids. The rash can lead to a host of other serious eye problems, including trichiasis.

Congenital Eyelid Conditions – Some people are born with eyelids that have extra loose skin or the eyelid is turned inward. These types of conditions can cause trichiasis due to the way the eyelashes rub against the rest of the eye area.

Trachoma – Trachoma is a serious eye infection that is a leading cause of preventable blindness across the world. While trachoma is rare in the US, it is widespread in developing nations. Trichiasis is one of the results of this infection.

Rubbing Eyes – In children, trichiasis can occur from rubbing their eyes too much.
