Abnormal Eyelid Positions (Ectropion/ Entropion)

 

What is an ectropion?

Ectropion occurs when the lower eyelid turns outwards away from the eye and the inner surface of the eyelid (conjunctiva) is exposed.

 

 

 

 

 

What is the cause of an ectropion?

  • Weakness in the muscles around the eye due to ageing

  • Scarring of the eyelids from burns, infection or injury.

  • Weakness in facial muscles (i.e. Bell’s palsy.)

What are the symptoms and signs of an ectropion?

  • The inner lining of the eyelid (conjunctiva) becomes dry and sore due to exposure.

  • Watering of the affected eye.

  • A drooping tear duct in the corner of the eye (punctal ectropion ) allows tears to roll off the face.

  • Inability to close eye

What is the treatment for an ectropion?

In moderate to severe cases of ectropion surgery is required to tighten the muscles of the eyelid. If only the tear duct opening (called the punctum) is turned outward then a burning procedure (cautery) of the lining of the eyelid (conjunctiva) can tighten the lower lid back into place.

What is an entropion?

An entropion occurs where an eyelid turns inwards towards the eye. The eyelashes rub against the surface of the eye (the cornea). The lower eyelid is most commonly affected.

 

 

 

 

 

 

 

 

 

What are the symptoms and signs of an entropion?

  • Eye pain and irritation

  • Watery eye.

  • Corneal damage and ulceration that can lead to blindness.

What causes an entropion?

The most common cause of entropion is weakness in the muscles around the eye due to ageing. Other causes are infection or injury of the eyelids.

What is the treatment for an entropion?

  • Taping the eyelid to the cheek temporarily. Surgery is usually required to prevent corneal damage.

  • Lubricating eye ointment to protect the eye.

  • Injecting the muscles of the eyelid with botulinum toxin. Again, a temporary respite.
