A chalazion is a swollen bump on the eyelid. It happens when the eyelid’s oil gland clogs up. It may start as an internal hordeolum (stye). At first, you might not know you have a chalazion as there is little or no pain. But as it grows, your eyelid may get red, swollen, and sometimes tender to touch. If the chalazion gets large, it can press on your eye and cause blurry vision. Rarely, the whole eyelid might swell.
A chalazion can develop and you might not see any symptoms. When there are symptoms, they can include:
Soak a clean washcloth in hot water and hold it to your eyelid for 10–15 minutes at a time, 3–5 times a day. Keep the cloth warm by soaking it in hot water often. For a chalazion, this warm compress helps the clogged oil gland to open and drain. You can help the gland clear itself by gently massaging around the area with your clean finger.
If your chalazion is very swollen, your ophthalmologist may give you a steroid shot (cortisone) to reduce the swelling.
