Ectropion

What is an ectropion?

An ectropion is where the lower eyelid turns outwards away from the eye. Part of the inner surface of the eyelid can be seen. Both eyes are usually affected.

What are the symptoms of an ectropion?

• The inner lining of the eyelid that droops forward may become dry and sore.
   
• Watery eyes. The part of the eyelid next to the nose usually droops the most. This is next to the tear duct where tears normally drain into the nose. The drooping eyelid may prevent the tears from draining, and the eye may become constantly watery. Tears may roll off the drooping part of the eyelid.
   
• Damaged cornea. The eyes may not close properly if you have an ectropion. Therefore the cornea (the front of the eye) is not fully protected and may get damaged. A corneal ulcer may develop. The cornea is vital for vision and a damaged cornea may affect eyesight.

What is the cause of an ectropion?

In the UK it mainly affects older people where the small muscles around the eyelid become weak.

It may also be caused by any condition that causes scarring of the eyelid, or scarring near the eyelid. Generalised weakness of the facial muscles (facial palsy) may also include weakness of the eyelid and cause an ectropion.

What is the treatment for an ectropion?

The usual treatment is an operation to 'tighten' the skin and muscles around the eyelid. It usually works well. The best results are obtained if the condition has not become too severe. More extensive plastic surgery may be needed in severe cases.

Whilst awaiting an operation you may be prescribed some lubricating eye ointment to help protect the cornea.
