📋Overview
Chalazion is a common, benign eyelid condition characterized by a localized, painless swelling caused by chronic inflammation of a blocked meibomian gland. It is sometimes confused with a stye but differs in cause and presentation. The modern preferred term is chalazion; older terms include meibomian cyst or internal hordeolum (though the latter is an acute infection).
