Entropion

What is entropion?

Entropion is a medical condition in which the eyelid (usually the lower lid) folds inward. It is very uncomfortable, as the eyelashes constantly rub against the cornea.

The upper or lower eyelid can be involved, and one or both eyes might possibly be affected. When entropion occurs in both eyes, this is known as "bilateral entropion." Trachoma infection might possibly cause scarring of the inner eyelid, which might possibly cause entropion. In human cases, this condition is most common to people over 60 years of age.

Four basic anatomic defects which might possibly lead to entropion:

  1. Horizontal lid laxity
  2. disinsertion or attenuation of retractors
  3. preseptal orbicularis overiding the pretarsal orbicularis muscle
  4. enophthalmos

 

Patients also find relief by pulling the lower eyelid away from the eye
