The eversion of blepharons - a cicatrical eversion is formed owing to tightening a skin of blepharons after wounds, combustions, a systemic lupus erythematosus and other pathological processes. The spastic eversion results from reduction of an orbital part of a circular muscle of an eye. A senile eversion - consequence of delicacy of this muscle. The paralytic eversion happens only on a lower eyelid and arises at a paralysis of a facial nerve.

Signs, current. The edge of a century lags behind an eye or will turn on downwards owing to what the mucosa is turned out outside. It gradually dries and hypertrophies. Together with a century the lacrimal opening that conducts to a dacryagogue and a maceration of a skin departs from an eye. From not closing of a palpebral fissure the keratitis with the subsequent opacification of a cornea can develop.
