What is an entropion and what are the symptoms?
An entropion refers to a condition in which the lower eyelid turns inwards against the surface of the eye.
A mild entropion causes irritation and watering of the eye. The irritation can lead to squeezing of the eyelids, which in itself causes further in-turning of the eyelid and more severe discomfort.
The eye may become red, and the cornea may become scratched by the eyelashes rubbing against it. Rarely, a severe infection of the cornea can occur, leading to potential permanent loss of vision.
Pending surgical correction, daily cleaning of the eyelids, and lubricant gel and ointment can help to relieve any irritation.
What causes an entropion?
The most common cause of a lower eyelid entropion is an age-related instability of the eyelid structures. The majority are, therefore, seen in older patients. Other causes include previous trauma, chemical injuries, and inflammation of the conjunctiva on the inside of the eyelid.
