眼睑内翻（entropion） The eyelid entropion, especially abnormal eyelid to eye direction curl position. When the entropion reaches a certain level, the eyelashes also fall into the eyeball. Therefore, entropion and trichiasis often exist at the same time. Entropion can be divided into three categories: 1, congenital entropion, 2, spastic entropion, 3, and cicatricial entropion. Congenital entropion is usually bilateral, with spastic and cicatricial entropion, which can be unilateral. Patients with photophobia, tears, pain, eyelid spasm. Check, especially of visible tarsal palpebral margin curl to eye direction. Trichiasis friction cornea, corneal epithelial shedding, diffuse fluorescein staining.
