[Overview] Inverted eyelashes (inverted eyelashes) are abnormal conditions in which the eyelashes grow backward and touch the eyeball. It is often due to trachoma, blepharitis, blepharitis, lid trauma or lid burn. Clinical manifestations】 1. The number of ingrown eyelashes varies from 1 or 2 to all eyelashes. 2. Often there is eye pain, tearing and foreign body sensation. 3. The eyelashes rub the eye for a long time, resulting in conjunctival congestion, corneal clouding, and vascularization, which can lead to corneal ulceration in severe cases. If there are only one or two impinging eyelashes, use eyelash pullers to remove them. In case of regrowth, it can be removed again. 2. For more thorough treatment, electrolysis should be used to destroy the hair follicles of the ingrown eyelashes and reduce the chance of regrowth. 3.If there are more ingrown eyelashes, corrective surgery should be performed.
