A chalazion, also known as a meibomian gland lipogranuloma , is a cyst in the eyelid that is caused by inflammation of the meibomian gland , usually on the upper eyelid. Chalazia may occur in the upper or lower lids, causing redness, swelling and soreness in some cases. It's the name given to a small cyst or lump in the eyelid which is caused by a blocked gland. A chalazion is usually a reaction to trapped oil secretions and not caused by bacteria, although the site can become secondarily infected by bacteria. This lump, which may feel like a small smooth pea in the eyelid, is usually just a little further back from the edge of the eyelid. If the lesion is large, vision in the involved eye may be blurred or distorted. Inflammation and pointing may sometimes occur, and the tiny associated abscess may spontaneously drain. In many cases, however, the chalazion becomes chronic , and the patient presents desiring removal. Treatment initially involves application of warm compresses in attempt to cause spontaneous drainage. Antibiotics , both topically and orally, are of little use. If the patient desires, the chalazion can usually be surgically opened and drained as a minor in-office procedure. Some patients, especially those with rosacea, are prone to recurrences.
