Ectropion is the turning out of the eyelid so that the inner surface is exposed. It most often affects the lower eyelid.
Ectropion is very often caused by the aging process. The connective tissue of the eyelid becomes weaker, which causes the lid to turn out so that the edge of the lower lid is no longer against the eyeball. It can also be caused by:
- A defect that occurs before birth (for example, in children with Down syndrome)
- Facial palsy
- Scar tissue from burns
Exams and Tests
The health care provider will make a diagnosis by doing an exam of the eyes and eyelids. Special tests are not needed most of the time.
Artificial tears (a lubricant) may ease dryness and keep the cornea moist. Surgery to tighten the muscles that hold the eyelids in place is very often effective. It may be done as outpatient surgery using medicine to numb the area (local anesthesia).
The outcome very often good with treatment.
Corneal dryness and irritation may lead to:
Corneal ulcers can threaten vision.
When to Contact a Medical Professional

If you have ectropion, get emergency medical help if you have:
- Vision that is getting worse
- Sensitivity to light
- Eye redness that is getting worse quickly
Most cases are cannot be prevented. Using artificial tears or lubricating ointments may prevent injury to the cornea.
