Entropion is a condition in which the lower eyelid turns inward, rubbing against the eye. Entropion occurs most commonly as a result of aging. Infection and scarring inside the eyelid are other causes of entropion. When the eyelid turns inward, the eyelashes and skin rub against the eye, making it red, irritated and sensitive to light and wind. Over time, many people develop excess eyelid skin. Eyelid skin is the thinnest skin of the body, so it is more likely to stretch. In the upper eyelid, this stretched skin may limit the field of vision, and may produce a feeling of heaviness and a tired appearance. In the lower eyelid, "bags" form. The excess skin in the upper eyelids can be removed surgically to improve the field of vision and other symptoms. Removal of the excess skin in either the upper or lower eyelids may improve appearance. If any fatty tissue is present, it may be removed at the same time.

Causes of Entropion
Entropion can be present at birth (congenital).
In babies, it rarely causes problems because the lashes are very soft and do not easily damage the cornea. In older people, the condition is usually caused by a spasm and weakening of the muscles surrounding the lower part of the eye. This causes the lid to turn inward.
Although rare in North America and Europe, trachoma infection can cause scarring of the inner side of the lid, which may cause entropion. Trachoma scarring is one of the three leading causes of blindness in the world.
