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.
Chalazia or chalazion is a painless, slow-growing, inflammatory cyst that develops in a small tear gland of the eyelid. These small glands are termed meibomianitis glands. A chalazion forms when blockage or inflammation of a mebiomian gland occurs. Chalazions are often a result of an unhealed stye, or an inflammatory disease called blepharitis. Certain medications, hormonal changes or environmental conditions can make a person more likely to develop a chalazion.
