A chalazion is a small bump in the eyelid caused by a blockage of a tiny oil gland. A chalazion is caused by a blocked duct in one of the meibomian glands. These glands are located in the eyelid directly behind the eyelashes. They produce a thin, oily fluid that lubricates the eye.
Chalazion or meibomian cyst (lump in eyelid) Chalazion overview A chalazion, also known as a meibomian cyst, is a lump in the eyelid that is caused by inflammation of a gland within the skin. Typically, this lump grows over days and weeks and is occasionally red, warm or painful. The gland involved in the formation of a chalazion is a modified sweat gland that lies within the eyelid and opens onto the inside of the eyelid. This gland produces oil. When this gland becomes blocked, it can rupture and the inflammation process begins.
