Chalazion

What is a chalazion?

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.

What are the symptoms of a chalazion?

Each child may experience symptoms differently, but the most common symptoms of a chalazion include:

  • a small bump that can usually be felt in the eyelid
  • a gradual swelling of the eyelid
  • discomfort in the eye or difficulty seeing if the chalazion is large

Swelling associated with a chalazion is not usually painful, but the entire lid may become swollen and painful if the initial chalazion becomes infected.

Because the symptoms of a chalazion may resemble other conditions or medical problems, you should always consult your child's physician for a diagnosis.
