Entropion describes the turning in of the eyelid causing the skin and lashes to rub against the surface of the eye. Often this condition is misdiagnosed as being just the lashes turning in, however even if the lashes are then removed the eye discomfort does not fully resolve as the skin of the in-turned eyelid will rub and irritate the eyeball.
The most common group of people who get entropion are the elderly with loosening of the eyelid, it can also happen in patients who have nerve damage to the muscles of the eyelid. Rarely is it caused by inflammation and scarring of the inner surface (“conjunctiva”) of the eyelid pulling the lid in wards towards the eyeball.
Children and infants can also get a form of entropion called epiblepharon.
