Entropion is the medical term used to describe a condition where the lower eyelid and eyelashes turn or roll inward towards the eye. This causes the eyelid and its lashes to constantly rub against the cornea (the front part of the eye) and conjunctiva (the mucous membrane that protects the eye).


Entropion is usually due to relaxing of the tissues of the eyelid as a result of aging changes, Thus, it is most often seen in elderly people who develop stretching of the structures supporting the lower eyelid to turn inward. Entropies may also be caused by inflammation or scarring on the inner surface. Sometimes, entropion is present at birth (congenital) if the eyelids are not formed normally.


Entropion can cause chronic irritation to the eyelid and the eye. This can result in excessive tearing, crusting on the eyelid and mucus discharge, a feeling that something is in your eye, irritation of the cornea, and impaired vision.

Damage to the cornea (the clear part of the eye), including infection and scarring, may develop due to the chronically turned in eyelid. These are important reasons for having this condition repaired before permanent damage occurs to the eyes.


The usual management for entropion involves tightening of the eyelid and its attachments to restore some of its elasticity and to reposition it normally. There are a number of surgical techniques for successfully managing an entropion and each surgeon will have a preferred method.

If a patient is not able to undergo surgery, tape or sutures can be used to temporarily reposition the eyelid and to protect the eye. Lubricating drops and ointments for the eye are also helpful on a temporary basis.

Entropion seen in babies usually resolves spontaneously within a few months, but occasionally needs to be treated.

When other factors contribute to the presence of an entropion, they may require special treatment. Medications are frequently used to control inflammation or infection of the eyelid and to treat scars. Scar excision and tissue grafts may also occasionally be necessary.
