What is a chalazion?

A Answers (2)

  • A Dr David Coats, MD, Ophthalmology, answered on behalf of American Academy of Ophthalmology's EyeSmart
     A chalazion occurs when one of the oil glands of the eyelids becomes blocked, resulting in the appearance of a lesion. Treatment of a chalazion is not an emergency and these lesions frequently resolve spontaneously with time. 
  • A chalazion (pronounced kuh-LAY-zee-un) is an enlargement of an oil-producing gland in the eyelid called the meibomian gland. It forms when the gland opening becomes clogged with oil secretions. It is not caused by an infection from bacteria, and it is not cancerous.

    If an internal hordeolum doesn’t drain and heal, it can turn into a chalazion. Unlike a stye, a chalazion is usually painless.
