Ectropion

What is ectropion?

Normally the upper and lower eyelids rest comfortably against the surface of the eye. They help to protect the surface of the eye and keep it moist and lubricated with your tears. Ectropion occurs when the eyelid (usually the lower eyelid) turns out away from the eye. This can lead to drying of the front of the eye, which can cause irritation, redness, and a watery eye.

How does it occur?

Different types of ectropion occur from different causes:

• Involutional ectropion occurs if the eyelid tissues become too loose, and cause the eyelid to turn out. Eyelid tissues usually get looser as you get older
• Cicatricial ectropion occurs when the skin of the eyelid becomes scarred and pulls the eyelid out away from the eye. Scarring can occur from many causes including injury, surgery, sun damage, and skin cancer.
• Paralytic ectropion occurs when the nerve controlling the muscles in the face and eyelid becomes paralyzed. The loss of muscle tone results in sagging and turning out of the lower eyelid.

What are the symptoms?

Symptoms of ectropion include:

• gritty feeling
• watery eyes
• decreased or cloudy vision
• discharge
• redness of the eye

How is it diagnosed?

Your healthcare provider will ask about your symptoms, examine your eyes, and perform tests. Tests you may have are:

• an exam using a special microscope (a slit lamp) to look closely at your eye
• photographs to document the appearance of your eyelids and to help in your follow up care

How is it treated?

If you have mild ectropion with few symptoms your healthcare provider may recommend treatment with artificial tear drops and ointment to keep your eye comfortable. More severe ectropion will require surgery. Your healthcare provider may recommend surgery to tighten your eyelid. This may be done with or without a skin graft, usually using a small piece of the extra skin of your upper eyelid.

How long will the effects last?

Ectropion, if not corrected by surgery, gradually gets worse over time. Your eyelid and eye may become more irritated over time. The opening of your tear drainage system in the inner corner of your lower eyelid may become scarred and shut, causing your eye to water all the time.

How can I prevent ectropion?

Ectropion cannot be prevented.
