Chalazion
Disease Information
Overview
A chalazion is a persistent inflammation or swelling of the upper or lower eyelid that can also include the middle part of the eyelid. Swelling may also occur in other parts of the eye due to a secondary infection.
- A chalazion is caused by a blockage of one of the glands in the eyelid.
- Swelling associated with a chalazion is not usually painful, but the entire lid may become swollen and painful if the initial chalazion becomes infected.
- A small chalazion may go away on its own without treatment in a couple of months.
