Overview

Ectropion (ek-TROH-pee-on) is a condition in which your eyelid turns outward. This leaves the inner eyelid surface exposed and prone to irritation.

Ectropion is more common in older adults, and it generally affects only the lower eyelid. In severe ectropion, the entire length of the eyelid is turned out. In less severe ectropion, only one segment of the eyelid sags away from the eye.

Artificial tears and lubricating ointments can help relieve symptoms of ectropion. But usually surgery is needed to fully correct the condition.

Symptoms

Normally when you blink, your eyelids distribute tears evenly across your eyes, keeping the surfaces of the eyes lubricated. These tears drain into small openings on the inner part of your eyelids (puncta).

If you have ectropion, your lower lid pulls away from your eye and tears don't drain properly into the puncta. The resulting signs and symptoms can include:

• Watery eyes (excessive tearing). Without proper drainage, your tears may pool and constantly flow over your eyelids.
• Excessive dryness. Ectropion can cause your eyes to feel dry, gritty and sandy.
• Irritation. Stagnant tears or dryness can irritate your eyes, causing a burning sensation and redness in your eyelids and the whites of your eyes.
• Sensitivity to light. Stagnant tears or dry eyes can irritate the surface of the cornea, making you sensitive to light.

When to see a doctor

See your doctor if your eyes are constantly watering or irritated, or your eyelid seems to be sagging or drooping.

Seek immediate care if you have been diagnosed with ectropion and you experience:

• Rapidly increasing redness in your eyes
• Sensitivity to light
• Decreasing vision

These are signs and symptoms of cornea exposure or ulcers, which can harm your vision.

Causes

Ectropion can be caused by:

• Muscle weakness. As you age, the muscles under your eyes tend to weaken, and tendons stretch out. These muscles and tendons hold your eyelid taut against your eye. When they weaken, your eyelid can begin to droop.
• Facial paralysis. Certain conditions, such as Bell's palsy, and certain types of tumors can paralyze facial nerves and muscles. Facial paralysis that affects eyelid muscles can lead to ectropion.
• Scars or previous surgeries. Skin that has been damaged by burns or trauma, such as a dog bite, can affect the way that your eyelid rests against your eye. Previous eyelid surgery (blepharoplasty) can cause ectropion, particularly if a considerable amount of skin was removed from the eyelid at the time of surgery.
• Eyelid growths. Benign or cancerous growths on your eyelid can cause the lid to turn outward.
• Genetic disorders. Rarely, ectropion is present at birth (congenital), when it is usually associated with genetic disorders, such as Down syndrome.

Diagnosis

Ectropion can usually be diagnosed with a routine eye exam and physical. Your doctor may pull on your eyelids during the exam or ask you to close your eyes forcefully. This helps him or her assess your eyelid's muscle tone and tightness.

If your ectropion is caused by a scar, tumor, previous surgery or radiation, your doctor will examine the surrounding tissue as well.

Understanding how other conditions cause ectropion is important in choosing the correct treatment or surgical technique.

Complications

Ectropion leaves your cornea irritated and exposed, making it more susceptible to drying. The result can be abrasions and ulcers on the cornea, which can threaten your vision.

Lifestyle and home remedies

These lifestyle tips may relieve your discomfort from ectropion:

• Use eye lubricants. Artificial tears and eye ointments can help keep your cornea lubricated and prevent vision-threatening damage. Using an eye ointment and wearing a moisture shield over your eye is particularly useful overnight.
• Wipe your eyes carefully. Constantly wiping watery eyes can make your under-eye muscles and tendons stretch even further, worsening your ectropion. Wipe from the outer eye up and in toward the nose.

Risk factors

Factors that increase your risk of developing ectropion include:

• Age. The most common cause of ectropion is weakening muscle tissue associated with aging.
• Previous eye surgeries. People who have had eyelid surgery are at higher risk of developing ectropion later.
• Previous cancer, burns or trauma. If you've had spots of skin cancer on your face, facial burns or trauma, you're at higher risk of developing ectropion.
