Trichiasis is a common eyelid problem. With trichiasis, 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.
Anyone can develop trichiasis, although it is more common in adults. Eye infection, swelling of the eyelid, autoimmune conditions and trauma all cause trichiasis.
If you have trichiasis, your eye may feel irritated by the sensation of having something in your eye. Other symptoms include:
- redness
- tearing, and
- sensitivity to bright light
Trichiasis can cause a corneal abrasion or even a corneal ulcer.
