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: How It Develops and How itâs Treated. A chalazion is a small cyst on the eyelidâusually smaller than a peaâcaused by blockage of one of the meibomian glands. The meibomian glands are tiny glands within the eyelid that produce oil to lubricate the eye. When these glands are blocked, oil builds up inside the gland, producing a little bump called a chalazion.
