בסדרה זו:Watering eyes
An entropion occurs where your eyelid turns towards the eye. The eyelashes then rub against the front of your eye (cornea). Irritation, pain and watering of the eye are the main symptoms. Taping the eyelid to your cheek, lubricant eye ointment and sometimes botulinum toxin injections help to control symptoms. People often require surgery if the problem persists.
At a glance
Entropion is when your eyelid turns inwards towards your eye.
Trichiasis is when eyelashes rub against the front of your eye.
It causes irritation, pain, and watery eyes.
Entropion usually affects older people in the UK due to muscle weakness.
Treatment can include taping the eyelid or botulinum toxin injections.
Surgery can correct the eyelid's position if the condition will not recover on its own.

Entropion and trichiasis
Eye with entropion
An entropion occurs where an eyelid turns inwards towards your eye. This causes the eyelashes to rub against the front of your eye (the cornea). Trichiasis is the medical term used to describe the eyelashes turning in against the front of the eye. The lower eyelid is most commonly affected.
Entropion symptoms
חזרה לתוכןIrritation and pain on the front of the eye.
A watery eye.
If left untreated, the front of the eye (the cornea) may become damaged (a corneal ulcer may develop). The cornea is vital for vision and a damaged cornea may affect eyesight.

Entropion causes
חזרה לתוכןIn the UK, entropion mainly occurs in older people, associated with weakness of the small muscles around the eyelid.
The main cause of entropion worldwide is trachoma. This is a common infection in tropical countries, which affects the front of the eye. This can lead to scarring and disruption to the eyelid, which makes it turn inwards.
Less common causes include scarring (from eye infections, trauma, Stevens-Johnson syndrome or chemical damage) or muscle spasm (spasticity). Rarely, you can be born with a defect that causes the eyelid to turn inwards.
Entropion treatment
חזרה לתוכןIf the cause is likely to be temporary, such as an infection or minor injury, the following may be enough until the condition recovers:
Taping the eyelid to your cheek; או
Injecting the muscles of your eyelid with botulinum toxin.
Lubricating eye ointment is often prescribed in the meantime to protect the front of your eye (cornea).

What is entropion repair surgery?
חזרה לתוכןIf you have a condition which is unlikely to recover by itself, you will be offered surgery. A small operation is performed to turn the eyelid back to its normal position. This stops the eyelashes from rubbing on the eye. The operation is usually successful and prevents any further damage to the front of the eye.

Blepharospasm
Blepharospasm is a condition in which blinking or spasmodic closing of the eyes occurs at an increased rate. It ranges from a mild, embarrassing condition of twitching or fluttering of an eyelid to severe spasms of eye closure which interrupt useful vision. Secondary blepharospasm is a common response to many common eye conditions, and can be caused by some conditions affecting the nervous system. This leaflet is mainly about primary blepharospasm, also called benign essential blepharospasm (BEB). BEB cannot be cured, but is usually successfully managed with botulinum toxin injections, repeated at intervals. In the UK, if you have blepharospasm you must notify the Driver and Vehicle Licensing Agency (DVLA).

שאלות נפוצות
What is the difference between entropion and trichiasis?
Entropion is when the eyelid itself turns inwards towards the eye. Trichiasis is the medical term used to specifically describe the eyelashes turning in against the front of the eye, which can be caused by entropion.
Which eyelid is most commonly affected by entropion?
The lower eyelid is most commonly affected by entropion.
What are the potential long-term consequences if entropion is not treated?
If entropion is left untreated, the continuous rubbing of eyelashes against the front of the eye (cornea) can lead to damage, potentially causing a corneal ulcer. Since the cornea is vital for vision, this damage can affect eyesight.
Besides aging, what are some other less common reasons someone might develop entropion?
Less common causes of entropion include scarring from eye infections, trauma, Stevens-Johnson syndrome, or chemical damage. Muscle spasms (spasticity) can also be a cause. Very rarely, some people are born with a defect that causes their eyelid to turn inwards.
How do temporary treatments like taping or injections help with entropion?
If the cause of entropion is likely to be temporary, such as a minor injury or infection, taping the eyelid to the cheek or injecting the eyelid muscles with botulinum toxin can help until the condition resolves on its own. These methods aim to reposition the eyelid or relax the muscles temporarily.
What is the purpose of lubricating eye ointment when treating entropion?
Lubricating eye ointment is often prescribed to protect the front of your eye (the cornea) from irritation and damage while other treatments are taking effect or while awaiting surgery.
