Entropion

A turning in of the margins of the eyelids so that the lashes rub against the cornea and the conjunctiva. Entropion is sometimes present from birth, especially in overweight babies. It is common in the elderly, due to weakness of the muscles around the lower eye. Entropion of the upper or lower lid may be caused by scarring, for example that due to trachoma. Entropion in babies does not disturb the eye and usually disappears within a few months. In later life, entropion can cause irritation, conjunctivitis, damage to the cornea, or problems with vision. Surgery to correct entropion can prevent such conditions.
