Ectropion

 

Ectropion is the turning out of the eyelid so that the inner surface is exposed. It most often affects the lower eyelid.

Causes

Ectropion is very often caused by the aging process. The connective (supporting) tissue of the eyelid becomes weak. This causes the lid to turn out so that the side 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

Symptoms

 

Symptoms include:

  • Dry, painful eyes
  • Excess tearing of the eye (epiphora)
  • Eyelid turns outward (downward)
  • Long-term (chronic) conjunctivitis
  • Keratitis
  • Redness of the lid and white part of the eye

If you have ectropion, you will most likely have excess tearing. This happens because the eye gets dry, then makes more tears. The excess tears can't get into the tear drainage duct. Therefore, they build up inside the lower lid and then spill over the edge of the lid onto the cheek.

 

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.

 

Treatment

 

Artificial tears (a lubricant) may ease dryness and keep the cornea moist. Ointment may be helpful when the eye can't close all of the way, such as when you are asleep. Surgery is very often effective. The surgeon will tighten the muscles that hold the eyelids in place. It may be done as outpatient surgery setting. A medicine is used to numb the area (local anesthesia) before the surgery.

 

Outlook (Prognosis)

 

The outcome very often good with treatment.

 

Possible Complications

 

Corneal dryness and irritation may lead to:

  • Corneal abrasions
  • Corneal ulcers
  • Eye infections

Corneal ulcers can cause vision loss.

 

When to Contact a Medical Professional

 

Call your provider if you have symptoms of ectropion.

If you have ectropion, get emergency medical help if you have:

  • Vision that is getting worse
  • Pain
  • Sensitivity to light
  • Eye redness that is getting worse quickly

 

Prevention

 

Most cases are cannot be prevented. You may use artificial tears or ointments to prevent injury to the cornea.

    The eye is the organ of sight, a nearly spherical hollow globe filled with fluids (humors). The outer layer or tunic (sclera, or white, and cornea) is fibrous and protective. The middle tunic layer (choroid, ciliary body and the iris) is vascular. The innermost layer (the retina) is nervous or sensory. The fluids in the eye are divided by the lens into the vitreous humor (behind the lens) and the aqueous humor (in front of the lens). The lens itself is flexible and suspended by ligaments which allow it to change shape to focus light on the retina, which is composed of sensory neurons.
