Abnormal Eyelid Position (Entropion/Ectropion) Repair
Abnormal Eyelid Position
The position and function of the eyelids are critical to the health and function of the eyes. Eyelids may become inflamed (blepharitis), scarred (cicatrized), loose and lax (floppy eyelid), turned-in (entropion), turned-out (ectropion), pulled away from the eye (retracted), and unable to close (lagophthalmos). Each of these conditions can irritate the eye (ocular surface disease) leading to pain, foreign body sensation, tearing, redness, discharge, and even scarring and loss of vision in the eye.
Surgical correction of these conditions is directed toward re-establishing the proper anatomic position and function of the eyelids.
What is Entropion?
Entropion is a condition where the eyelid turns inward and causes the eyelashes to rub and irritate the surface of the eye (the cornea). If the condition is not treated serious inflammation and permanent damage to the surface of the eye may occur.
What is Ectropion?
Ectropion is a condition where the eyelid turns out and falls away from the eye. Although typically not as irritating as entropion, ectropion can lead to chronic eye pain and dryness. The surface of the eye is unhealthy and dry because the eyelid does not touch and lubricate the surface of the eye. Often the opening of the tear drainage system (the puncta) is pulled away from the eye and tear film causing inadequate drainage of tears into the lacrimal (tear drainage) system. This can cause excess tears to accumulate on the surface of the eye or roll down the cheeks.
What is Lid Retraction?
Lid retraction is a condition where the eyelid is pulled away from its normal resting position. Lid retraction can happen in either the upper eyelid or the lower eyelid. Lid retraction in the upper eyelid is typically associated with thyroid eye disease and causes patients with this condition to develop a classic “stare.” Lid retraction in the lower eyelid can occur from aging changes, a history of prior surgery including cosmetic eyelid surgery, and scarring from cancer, radiation, or tumor growth. Lid retraction may need to be addressed with grafts that push up the lower eyelid into a higher position.
