Picture of Chalazion (Eyelid Cyst)
A chalazion is a tiny lump of the upper or lower eyelid caused by inflammation of a gland of the lid. It may be soft and fluid-filled or firmer. A chalazion is also referred to as a meibomian cyst, tarsal cyst, or conjunctival granuloma. The narrow opening through which a meibomian gland secretes its material can become clogged from narrowing of the opening or hardening of the sebaceous liquid near the opening. If this occurs, the gland will have a backup of the material it secretes and it will swell. Most chalazions are treated with warm compresses to the eyelid to promote healing and circulation of blood to the inflamed area. Doctors may prescribe an antibiotic drop or ointment to be used immediately after the compresses. If the chalazion persists and is causing an unsightly lump, it can be removed surgically through the inside of the lid.
