Eyelid Ectropion: Causes and Treatment
Eyelid ectropion occurs when the edge of the eyelid, most commonly the lower eyelid, loses its normal contact with the eye and turns outward.
In addition to changing the appearance of the eyelid, ectropion can cause constant tearing, irritation, dryness, redness, and foreign-body sensation. This happens because the eyelid can no longer distribute tears normally, and part of the conjunctiva or, in more advanced cases, the cornea may remain exposed.
What causes ectropion?
The most common cause is age-related laxity of the eyelid tissues. Over time, the eyelid and its supporting structures lose tension and may begin to pull away from the eye.
However, ectropion can also occur because of:
scarring or a shortage of skin that pulls the eyelid downward;
trauma or previous surgery;
facial nerve palsy;
skin conditions;
lesions that alter the normal anatomy of the eyelid.
Identifying the cause is important because treatment is not the same for every type of ectropion.
Why can ectropion cause tearing?
Although it may seem contradictory, an eye with ectropion can be watery and dry at the same time.
Normally, the lower eyelid punctum remains in contact with the eye and collects tears so they can enter the tear drainage system. When the eyelid turns outward, this mechanism no longer works properly and tears may spill down the cheek.
At the same time, exposure of the ocular surface can cause irritation, which may stimulate even more tear production.
For this reason, persistent tearing should be evaluated to determine whether the problem comes from the tear drainage system, eyelid position, or the ocular surface.
How is ectropion treated?
Treatment depends on the cause and on how far the eyelid has moved away from the eye.
In mild cases, lubricating eye drops, gels, or ointments may help protect the ocular surface and relieve symptoms. However, these treatments do not correct the position of the eyelid.
When the problem is persistent or significant, surgical correction is usually necessary.
In age-related ectropion, surgery is generally intended to restore eyelid tension and bring the lid back into proper contact with the eye.
If scarring or insufficient skin is contributing to the problem, the scar may need to be released and, in some cases, a skin graft or another reconstructive technique may be necessary.
When ectropion is related to facial nerve palsy, protecting the cornea and improving eye closure are especially important.
How is the type of surgery chosen?
The examination evaluates eyelid position and laxity, the ability to close the eye, the ocular surface, and the position of the tear duct opening.
We also look for scarring, facial weakness, or other factors that may be responsible for the change in eyelid position.
Not every ectropion requires the same surgical technique. The procedure is selected according to the cause and the characteristics of each patient's eyelid.
Recovery after ectropion surgery
Recovery varies depending on the procedure, but some swelling and bruising around the eyelid are common during the first few days.
As the swelling improves, the eyelid gradually settles into its new position. Lubricants, medications, and local wound care may be recommended during this period.
The goal of surgery is to restore proper contact between the eyelid and the eye, improve eyelid function, and reduce symptoms such as tearing, irritation, and ocular exposure.
When should ectropion be evaluated?
An ectropion should be evaluated when the eyelid begins to pull away from the eye or when symptoms such as persistent tearing, dryness, irritation, or difficulty closing the eye develop.
If there is also eye pain, significant light sensitivity, or decreased vision, evaluation should be more prompt because the cornea may already be affected.
If you have noticed any of these changes, you can schedule an evaluation to determine the cause and available treatment options.
