chalazion
Thursday 11 March 2004

Definition : A chalazion, also known as a meibomian gland lipogranuloma, is a cyst in the eyelid that is caused by inflammation of a blocked meibomian gland, usually on the upper eyelid.
Chalazions differ from styes (hordeolums) in that they are usually painless apart from the tenderness caused when they swell up, and in size (chalazia tend to be larger than styes).
A chalazion may eventually disappear on its own after a few months, though more often than not, some treatment is necessary.
