Chalazion

What is a chalazion?

A chalazion is a small lump in the eyelid. It is similar to a stye, which is an infection of the edge of the eyelid caused by bacteria. However, a chalazion is away from the edge and is usually not caused by bacteria.

How does it occur?

A chalazion occurs when one of the small oil-producing glands in the eyelid becomes blocked. Oil secretions may become trapped and cause the lid to swell. The site of the lump may become infected by bacteria.

What are the symptoms?

Symptoms may include:

a red lump in your eyelid
pain near the lump
swelling of part or all of the eyelid
rarely, blurred vision.

How is it diagnosed?

Your doctor will examine your eye. He or she may send a sample of the tissue or fluid from around the lump to a lab to determine if bacteria are present or if the lump occurs for other reasons, such as cancer. Be sure that you tell your doctor if you have any changes in your vision.

How is it treated?

Sometimes a chalazion will go away without treatment.

Usually, you will need to apply hot compresses to the closed eyelid. A compress is a clean washcloth moistened with hot water. You may need to apply hot compresses for at least 10 to 15 minutes at a time, 3 to 4 times a day, for several days. The moist heat helps to reduce inflammation and may help remove the plug that is blocking the oil gland.

If compresses do not relieve your symptoms, your doctor may prescribe steroids in the form of eyedrops or shots into the lump. Other treatment may include antibiotics in the form of eyedrops, ointment, pills, or shots.

If the chalazion is still present after 6 weeks, an ophthalmologist (a medical eye doctor) may need to remove the lump during minor surgery. The surgery is generally safe and effective.
