A swelling in the eyelid that may be painless
- Age, gender, genetics, and lifestyle are not significant factors
If an oil-secreting gland in the eyelid becomes blocked, the gland enlarges, creating a swelling called a chalazion. A chalazion may at first look like a stye, but, unlike a stye, it is not on the eyelid margin. Usually, the pain and redness associated with a chalazion disappear after a few days. However, if the swelling is large, it may cause long-term discomfort, and pressure on the front of the eye can interfere with vision.
What might be done?
If your doctor diagnoses a chalazion, he or she will probably wait for several weeks before arranging any treatment because it may disappear on its own. Meanwhile, if the chalazion is painful or irritating, holding a clean, warm, damp cloth against it may help.
A persistent chalazion can be treated by a simple operation in which a small cut is made in the inner surface of the eyelid and the contents of the swelling removed. The procedure is performed under local anaesthesia and is painless.
