trichiasis

Inturning or ingrowing of the eyelashes so that they rub against the CORNEA of the eye causing severe discomfort and possible abrasion, infection and ulceration. Trichiasis is a feature of TRACHOMA. Removal of lashes affords relief but definitive treatment involves plastic procedures to evert the lid margins. See also ENTROPION.

Trichiasis

A disease of the eye, in which the eyelashes, being turned in upon the eyeball, produce constant irritation by the motion of the lids.

trichiasis 

A condition in which the eyelashes due to entropion, blepharitis or injury, are directed towards the globe and cause irritation of the cornea and conjunctiva. Temporary relief may be achieved with epilation but permanent treatment consists of cryotherapy or laser ablation or in severe cases surgical excision and replacement with a mucous membrane (Fig. T19). See distichiasis; epilation; therapeutic soft contact lens.
