Ectropion is when your lower eyelid turns or sags outward, making it reddish, watery and irritating to the eye. Most common causes are age and trauma. Congenital ectropion also exists, but it is rarely an insolated anomaly. It may be associated with blepharophimosis, microphthalmia, orbital cysts, Down syndrome or ichthyosis.

In cases of congenital ectropion the lacrimal points are not immersed in the lacrimal lakes, but remain turned outward, causing continuous tearing. The exposed part of the conjunctiva turns red, dries and hardens. The exposed area of the cornea can also wither and become dull.
Surgical treatment is an efficient and durable resolution of this problem as it restores the position of the eyelid.
