What is a chalazion?

A chalazion refers to the swelling and chronic inflammation of an oil gland of the eyelid. This swelling is due to trapped oil secretions within the gland. Typically, a gradual enlargement near the edge of the eyelid occurs. Occasionally, swelling of the entire eyelid may occur. A chalazion is not the same as a stye, which is an infection of an eyelash gland.

A chalazion may produce no symptoms and disappear without treatment. However, it usually remains, and as it enlarges toward the inside of the eyelid, the chalazion may cause blurred vision by exerting pressure and distorting the shape of the eye. In addition, infection may occur if bacteria are able to enter the gland.

There are several treatment methods for a chalazion. Antibiotic or steroid eye drops or injections may be used. Warm compresses and massage to express the secretions from the oil gland may also be recommended. The chalazion may have to be surgically removed or drained to promote healing. Once treated, chalazia tend to permanently disappear. However, some patients may develop chalazia on a recurrent basis. Should a chalazion repeatedly appear at the same place on the lid, a biopsy of the tissue may be necessary to determine that a more serious problem does not exist.
