Trichiasis

 

the abnormal growth of eyelashes into the eyeball, which causes pain, lacrimation, and traumatic defects of the cornea. Trichiasis may be congenital or acquired as a result of scarring in the region of the hair follicles, for example, in trachoma and other diseases. It involves the lashes of one or both eyelids. Treatment includes the removal of the ingrown eyelashes, coagulation of the hair follicles by means of diathermy, and plastic surgery.
