What is entropion?
Entropion happens when an eyelid turns inward towards the eye. This condition causes the eyelid skin and eyelashes to rub against the eyeball. That friction often causes discomfort and irritation of the cornea (front of the eye).
Entropion usually occurs in the lower eyelid. If it is not treated, it can damage the cornea and lead to vision loss.
How common is entropion?
Entropion is most common in people over 60 years old.
What causes entropion?
Lower eyelid looseness (laxity) or scarring usually causes entropion. This condition is common in older adults because the eyelid supports weaken with age allowing the eyelid muscles to turn the eyelids in. Other causes of an in-turned eyelid include an injury to the eye or having previous eye surgery.
What are the risk factors for entropion?
Aging is the biggest risk factor for entropion. People with a previous eye injury or surgery may develop entropion due to scar tissue on the eyelid.
What are the symptoms of entropion?
Entropion causes many uncomfortable symptoms in the eye. When the condition develops, symptoms may only occur occasionally. After time, the symptoms usually become constant. Signs of entropion include:
- Feeling of something in the eye
- Tearing (watering)
- Blurry vision
