What is Entropion?

screen-shot-2016-09-15-at-10-58-20-amEntropion is a condition in which your eyelid turns inward so that your eyelashes and skin rub against the eye surface. This causes irritation and discomfort.

When you have entropion, your eyelid may be turned in all the time or only when you blink hard or squeeze your eyelids shut. Entropion is more common in older adults, and it generally affects only the lower eyelid.

Artificial tears and lubricating ointments can help relieve symptoms of entropion. But usually surgery is needed to fully correct the condition. Left untreated, entropion can cause damage to the transparent covering in the front part of your eye (cornea), eye infections and vision loss.

What Are the Symptoms?

The signs and symptoms of entropion result from the friction of your eyelashes and outer eyelid against the surface of your eye.
You may experience:

  • The feeling that something is in your eye
  • Eye redness
  • Eye irritation or pain
  • Sensitivity to light and wind
  • Watery eyes (excessive tearing)
  • Mucous discharge and eyelid crusting
  • Decreased vision

When to see a doctor
Seek immediate care if you have received a diagnosis of entropion and you experience:

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

These are signs and symptoms of cornea injury, which can harm your vision.


Entropion can be caused by:

  • Muscle weakness. As you age, the muscles under your eyes tend to weaken, and the tendons stretch out. This is the most common cause of entropion.
  • Scars or previous surgeries. Skin scarred by chemical burns, trauma or surgery can distort the normal curve of the eyelid.
  • Eye infection. An eye infection called trachoma is common in many developing countries. It can cause scarring of the inner eyelid, leading to entropion and even blindness.
  • Inflammation. An irritation of the eye caused from dryness or inflammation can lead to an effort to relieve the symptoms by rubbing the eyelids or squeezing them shut. This can lead to a spasm of the eyelid muscles and a rolling of the edge of the lid inward against the cornea (spastic entropion).
  • Developmental complication. When entropion is present at birth (congenital), it may be caused by an extra fold of skin on the eyelid that causes turned-in eyelashes.

Risk factors

Factors that increase your risk of developing entropion include:

  • Age. The older you are, the greater your chances of developing the condition.
  • Previous burns or trauma. If you’ve had a burn or other injury on your face, the resulting scar tissue may put you at higher risk of developing entropion.
  • Trachoma infection. Because trachoma can scar the inner eyelids, people who have had this infection are more likely to develop entropion.


Corneal irritation and injury are the most serious complications related to entropion because they can lead to permanent vision loss.


Surgery is generally required to fully correct entropion.
