Entropion vs Ectropion: What’s the Difference?

Symptoms of Entropion

As the eyelid turns inward, the eyelashes and surrounding skin repeatedly come into contact with the surface of the eye. This friction can cause persistent discomfort and irritation.

Common symptoms include:

• A gritty sensation or the feeling of something in the eye.
• Redness and irritation.
• Excessive tearing.
• Increased sensitivity to light.
• Discomfort caused by the eyelashes rubbing against the ocular surface.

Symptoms may become more persistent as the condition progresses, particularly if the cornea becomes irritated.

Symptoms of Ectropion

Ectropion causes the lower eyelid to turn outward, exposing its inner surface and preventing it from resting properly against the eye.

Common symptoms include:

• Visible outward turning or drooping of the lower eyelid.
• Excessive tearing or watery eyes.
• Dryness and irritation.
• Redness of the exposed inner eyelid.
• A persistent gritty or uncomfortable sensation.

Although dryness and excessive tearing may seem contradictory, they can occur simultaneously.

When the lower eyelid turns outward, tears may no longer drain effectively through the normal drainage system. At the same time, the eyelid may be unable to distribute tears properly across the ocular surface, contributing to dryness and irritation.

How Are Entropion and Ectropion Diagnosed?

Entropion and ectropion are generally diagnosed through a specialist examination of the eyelids and ocular surface.

During the assessment, your specialist will examine the position and function of the eyelids, assess the strength and stability of their supporting tissues, and check for any signs of irritation or corneal damage.

Your medical history may also help identify the underlying cause, particularly if you have previously undergone eyelid surgery, experienced an injury or developed facial nerve problems.

Identifying the cause and severity of the condition is important when determining the most appropriate treatment.

When Should You See an Eye Specialist?

If you notice that your eyelid is turning inward or outward, particularly alongside persistent irritation, redness or excessive tearing, a specialist assessment can help establish the underlying cause.

You should also seek medical advice if your eyelid no longer appears to protect the eye properly or if your symptoms are becoming progressively worse.

Severe eye pain, significant sensitivity to light or changes in vision require urgent medical assessment, as these symptoms may indicate corneal damage or another condition requiring prompt treatment.

Frequently Asked Questions

Which Is More Common: Entropion or Ectropion?

Both conditions become more common with age, particularly as the supporting tissues of the lower eyelid weaken. Their relative frequency varies between populations, so neither condition can be considered universally more common.

Can You Have Both Entropion and Ectropion?

Yes. Although entropion and ectropion affect eyelid position in opposite directions, it is possible to experience both conditions in different eyelids or eyes.

Each condition requires an individual assessment to determine its underlying cause and the most appropriate treatment.

Can Entropion or Ectropion Go Away on Its Own?

Age-related entropion and ectropion generally do not resolve permanently without treatment because they involve structural changes to the eyelid.

However, some temporary or reversible causes of eyelid malposition may improve when the underlying problem is addressed. A specialist examination can help determine whether treatment is necessary.

Is Surgery Always Necessary?

Not always. Lubricating eye drops, ointments and other protective measures may help manage symptoms, particularly in mild cases or while awaiting further treatment.

However, when entropion or ectropion is caused by persistent structural changes, surgery is often required to restore the eyelid’s normal position.

Can Entropion or Ectropion Return After Surgery?

Both conditions can occasionally recur following surgical correction, particularly if the underlying changes affecting eyelid position continue to develop.

The likelihood of recurrence depends on several factors, including the original cause, the surgical technique and the condition of the surrounding tissues.

Can Entropion and Ectropion Damage Your Eyes?

Yes. Both conditions can potentially damage the ocular surface if left untreated, although they affect the eye in different ways.

With entropion, repeated friction from the inward-turning eyelashes and skin can cause corneal abrasions, inflammation and, in more severe cases, corneal ulceration.

With ectropion, the outward-turning eyelid may leave the ocular surface inadequately protected. Persistent exposure can contribute to dryness, inflammation and exposure keratopathy, which may lead to corneal damage in more severe cases.

Not every patient develops these complications. However, persistent symptoms should be assessed to identify any potential risks and determine whether treatment is appropriate.
