Is a chalazion like a pimple?

If the obstructed gland has bacteria within it, the gland may become infected. This is called a hordeolum, which does resemble a pimple, which really is an obstruction of an oil gland of the skin. A hordeolum may be tender to touch. A chalazion is not an infection but may follow or precede a hordeolum. A hordeolum is often referred to as a stye.

What is the treatment for a chalazion?

Most chalazions are treated with warm compresses to the eyelid to increase the circulation of blood to the inflamed area and promote healing. In addition, the doctor may prescribe an antibiotic drop or ointment to be used immediately after the compresses. If the chalazion persists and is causing an unsightly lump, it can be removed surgically as an outpatient procedure under local anesthesia. This excision is ordinarily performed through a small incision located on the inside of the affected lid. The removal of a chalazion neither alters the normal function of the lid nor decreases the amount of tears.

What is the prognosis of a chalazion?

In general, a chalazion does not affect sight. Rarely, the lump itself is large enough to distort the ocular surface and cause blurring of the vision. The vision will return to normal once the chalazion gets smaller or is removed. The pressure of the chalazion on the eye does not cause glaucoma. A chalazion is not malignant and has no potential to become malignant. A chalazion is not contagious.

How can a chalazion be prevented?

Some individuals have thicker Meibomian gland secretions than others and, therefore, have a greater risk of developing a chalazion. If you have had one chalazion, you are at greater risk of developing another one in the future. People with acne rosacea, because of alterations within the oil glands of the face, are at greater risk of developing chalazia. The regular use of warm compresses applied to the closed eyelids for five minutes before bedtime can be helpful in preventing the Meibomian glands from clogging during the night. In people with seborrhea of the lids and recurrent chalazia, warm compresses and careful cleansing of the lid margins can be helpful for prevention. Some patients with recurrent chalazia can benefit by chronic use of oral low-dose tetracycline, which changes the metabolism of the oil-producing glands.
