Entropion is an inward turning of the eyelid and lashes toward the eye, usually caused by relaxation of the eye muscles and tissue due to aging.
Entropion usually affects the lower lid. The skin and eyelashes rub against the eye and cause discomfort and tearing. The irritated eye can produce mucus and become red and sensitive to light and wind. If entropion is not treated, rubbing of the skin and eyelashes can lead to infection or scarring of the eye, which can cause vision loss.
Surgery can be performed to tighten the eyelid and return it to its normal position. The eyelid then protects the eye properly, and irritation and other symptoms subside.
Eyelid surgery to repair entropion is usually performed on an outpatient basis under monitored anesthesia care (MAC). Following surgery, your ophthalmologist (Eye M.D.) may prescribe antibiotic ointment and will instruct you to avoid heavy bending, lifting, and straining for seven days.
