What Is a Cyst?
4. Chalazion
A chalazion is a cyst that occurs on the eyelid when an oil gland is blocked. It is generally seen as a swelling on the middle part of the eyelid, painless, and erythematous (red). The swelling may gradually increase in size over several weeks. The eyelid can be tender with increased tearing, redness of the conjunctiva, and heaviness of the eyelid.
Treatment often includes the use of topical antibiotic eye drops such as fusidic acid or chloramphenicol. In some patients, the chalazion may also disappear on its own without further treatment. Healing of the chalazion can be facilitated through the application of a warm compress to the affected eye for 15 minutes several times a day to promote drainage and healing. Larger cysts can be surgically removed under local anesthesia.
