Entropion occurs most commonly as a result of aging. Infection and scarring inside the eyelid are other causes of entropion. When the eyelid turns inward, the eyelashes and skin rub against the eye, making it red, irritated, watery and sensitive to light and wind. If entropion is not treated, an infection may develop on the clear surface of the eye called the cornea.
With surgery, the eyelid can be turned outward to its normal position, protecting the eye and improving the symptoms.
