It is a condition in which the eyelid is rolled inward against the eyeball, typically caused by muscle spasm or by inflammation or scarring of the conjunctiva (as in diseases such as trachoma), and resulting in irritation of the eye by the lashes (trichiasis). Entropion is a medical condition in which the eyelid (usually the lower lid) folds inward. It is very uncomfortable, as the eyelashes constantly rub against the cornea and irritate it.
Symptoms: Symptoms of entropion include: Redness and pain around the eye. Sensitivity to light and wind. Sagging skin around the eye. Epiphora. Decreased vision, especially if the cornea is damaged.
Diagnosis: Entropion is generally easy to diagnose visually.It is mainly diagnosed by snap test. If you are losing collagen and muscle tone, this test helps confirm the visual diagnosis.
Treament: Treatment is a relatively simple surgery in which excess skin of the outer lids is removed or tendons and muscles are shortened with one or two stitches. General anesthesia is sometimes used before local anesthetics are injected into the muscles around the eye. Prognosis is excellent if surgery is performed before the cornea is damaged.
Epidemology: The primary morbidity is ocular surface irritation. Corneal abrasions and scars can occur.
