Chalazion: Symptoms & Signs

A chalazion is a lump in the upper or lower eyelid caused by inflammation of a gland of the lid. The swelling or lump may be soft or firm. Fluid may be present within the lump. A chalazion is very common and usually goes away on its own without any special treatment. A chalazion does not cause vision problems unless the lump is so large that it distorts the surface of the eye, but this is rare. Pain is usually not present. A chalazion is also known as a meibomian cyst, tarsal cyst, or conjunctival granuloma.

Causes of a chalazion

A chalazion is caused by clogging of the narrow opening through which a meibomian gland of the eyelid secretes its material. This can be due to narrowing of the opening or hardening of the sebaceous liquid near the opening.
