Usage

What does chalazion mean? A chalazion is a small bump that forms on the eyelid when a gland on the eyelid gets clogged. A chalazion can also be called sty (or stye), a meibomian cyst, or a hordeolum. The plural of chalazion is chalazia. Even though they occur on the eyelids and not the eye, chalazia are typically diagnosed and treated by ophthalmologists (eye doctors). Example: That bump on your eyelid might be a chalazion—you should get it checked out.
