Entropion
Entropion is an in-turning of the eyelid margin. This usually involves the lower eyelid, but occasionally may affect an upper eyelid. When the eyelid turns inward, the eye lashes may rub against the eye causing pain, irritation and mattering of the eye. If untreated, it can cause corneal ulceration, infection and may lead to visual loss.
Ectropion
Ectropion is an out-turning of the eyelid margin. This usually involves the lower eyelid. Ectropion can cause tearing, redness and irritation as the eye is exposed to wind, dust and dryness. It may also affect the closure of the eyelids. Ectropion may be related to previous cosmetic surgery, or can develop with aging.
Entropion and ectropion can occur in one or both eyes, and are repaired surgically. The surgery is performed in an outpatient facility. These procedures are usually considered "medically necessary" and as such, the cost is covered by insurance.
