Abstract

Congenital entropion is a pathology of the appendices corresponding to palpebral malposition characterized by an abnormal congenital inversion of the eyelid towards the eyeball. It consists of a rotation towards the inside of the margin of the eyelid, Anatomically, there is a horizontal or vertical release of the eyelid, a disinsertion of the retractors, and a hyper action of the orbicular. It may be of interest to one eye or bilateral. Often touches the lower palm. May cause mechanical irritation of the ocular surface by eyelashes that come in contact with the globe, which can lead to abrasion and ulceration of the cornea sometimes visual impairment. The first typical symptoms are a sensation of a foreign body, redness, watering, ocular discharge, and photophobia. The success of the result depends on the early diagnosis which must be appropriate, the choice of surgical technique, and the absence of preoperative complications. Often regress spontaneously, in case of failure surgery is necessary. Prognosis is often good.
