Overview

A chalazion (kuh-LAY-zee-un) is a slow-growing, painless lump in the eyelid that forms because of the swelling of an oil gland. It’s more common in adults between ages 30 and 50 than in children.

Causes

A chalazion is caused by a blocked oil gland in the eyelid. This can occur after a viral infection, or with a skin problem such as seborrhea or acne rosacea.

Risk Factors

A child is more at risk for a chalazion if he or she has any of these:

  • Viral infection
  • Seborrhea
  • Acne rosacea
  • Chronic blepharitis
  • Tuberculosis

These risk factors are more common in adults than children.

Symptoms

Symptoms can occur a bit differently in each child. They can include:

  • A small bump in the eyelid that can be felt
  • Swelling of the eyelid over time
  • Pain or trouble seeing if the chalazion is large

The symptoms of a chalazion can be like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.

Diagnosis

The healthcare provider will ask about your child’s symptoms and health history. He or she may also ask about your family’s health history. He or she will give your child a physical exam. Tests are not usually needed to confirm the diagnosis.

Treatment

Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is.

A small chalazion may go away on without treatment in a couple of months. A large chalazion or an infection caused by it may need to be treated. Treatment may include:

  • Applying warm, moist compresses to your child's eyes for 15 minutes at a time several times a day
  • Telling your child not to rub his or her eyes or squeeze or rub the chalazion
  • Having your child wash his or her hands often
  • Antibiotic eye drops

If symptoms don’t get better, surgery may be needed to drain or remove the chalazion.

Complications

If the chalazion becomes infected, the entire eyelid may become swollen and painful.

Next Steps

Tips to help you get the most from a visit to your child’s healthcare provider:

  • Know the reason for the visit and what you want to happen.
  • Before your visit, write down questions you want answered.
  • At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Also write down any new instructions your provider gives you for your child.
  • Know why a new medicine or treatment is prescribed and how it will help your child. Also know what the side effects are.
  • Ask if your child’s condition can be treated in other ways.
  • Know why a test or procedure is recommended and what the results could mean.
  • Know what to expect if your child does not take the medicine or have the test or procedure.
  • If your child has a follow-up appointment, write down the date, time, and purpose for that visit.
  • Know how you can contact your child’s provider after office hours. This is important if your child becomes ill and you have questions or need advice.
