A chalazion is a small bump that appears on your eyelid because of a blocked oil gland. It can develop on the lower or upper eyelid, and it often disappears without treatment in about one month. However, you should see a doctor if you think you might have a chalazion, especially if it is large enough to block your vision. A chalazion is similar to a stye (an infection of the base of the eyelash), but is usually smaller and not painful.
1. a not tender spot on your eyelid
2. a hard lump on your eyelid that you have never seen before
3. increased tearing of the eyes
4. blurred or blocked vision
5. sensitivity to light
Chalazia are sometimes confused with styes. You can tell the two types of eyelid lumps apart because chalazia do not usually hurt, while styes often do. In addition, chalazia are usually found away from the edge of the eyelid, while styes are most often found right on the eyelid edge. Even if you believe you have a chalazion, you should still see a doctor for an accurate diagnosis. Surgeries If the chalazion does not go away within about one month, you should return to your doctor to discuss your options. When a chalazion does not heal after treatment, it may need to be surgically removed. This is especially true if it keeps growing, blocks your vision, or leads to an astigmatism (an abnormal curving of the cornea). Surgery is usually a last resort and it is rarely required because most chalazia clear up with a combination of medication and home remedies.
It is not always possible to avoid getting a chalazion, especially if you are prone to this type of eye problem. However, you can reduce your chances of getting one by keeping dirt off your eyelids, which means keeping your face and hands clean. You can also put a warm compress on your eyelids for a few minutes each night before bed. This makes your oil glands less likely to become blocked, which may reduce your chances of getting a chalazion.
