Trichiasis

Trichiasis

Trichiasis is characterized by misdirected growth of eyelashes with a normal lid margin position. The lashes often cause irritation of the ocular surface and can lead to ulceration or scarring, which can impact a patient’s vision. Trichiasis results from abnormal eyelash growth, but it can also result from eye infections or previous damage to the eye/eyelid. This condition is most common in adults, and can be an age-related condition as skin becomes less elastic.

There is some confusion about difference between trichiasis and entropion. Trichiasis occurs when eyelashes incorrectly grow toward the cornea; entropion results when the eyelid itself sits incorrectly against the eye which results in many of the eyelashes rubbing along the cornea. At Idaho Eyelid and Facial Plastic Surgery, we have seen many cases of entropion that coincide with trichiasis.

Treatment

At Idaho Eyelid and Facial Plastic Surgery, trichiasis treatment involves removing the eyelashes or redirecting eyelash growth. When only a few eyelashes are misdirected, we can remove the lashes with forceps. There is a risk of new eyelashes growing back again in the wrong direction. When trichiasis involves lashes directed towards the cornea, surgery can remove them permanently. Ablative surgery or lasers can remove both the lashes and hair follicles. Other options include electrolysis and cryosurgery. If trichiasis is caused by epiblepharon, surgery may be a good option to to reposition the eyelashes.
