The term chalazion comes from a Greek word meaning a small lump. It refers to a swelling in the eyelid caused by inflammation of one of the small oil producing glands (meibomian glands) located in the upper and lower eyelids.

Stretching of the lower eyelid with age allows the eyelid to droop downward and turn outward. Eyelid burns or skin disease may also cause this problem.
