Chalazion

Alternative Names

Meibomian gland lipogranuloma

Definition of Chalazion

A chalazion is a small bump in the eyelid caused by a blockage of a tiny oil gland.

Causes, incidence, and risk factors

A chalazion develops in the glands that produce the fluid that lubricates the eye. These are called Meibomian glands. The eyelid has approximately 100 of these glands, which are located near the eyelashes.

Signs and tests

An exam of the eyelid confirms the diagnosis.

Treatment

A chalazion will often disappear without treatment in a month or so.

Expectations (prognosis)

Chalazia usually heal on their own. The outcome with treatment is usually excellent.
