Chalazia (chalazion) and styes are due to clogged oil glands of the eyelid and can become inflamed or infected. With chalazia, you will notice a painless bump on the eyelid whereas a stye will be a bump that appears red and inflamed with tenderness in the area. Styes and chalazia often improve with hot compresses and lid massage but a small residual bump may persist. If they do not improve, we often prescribe an antibiotic and steroid ointment. Other options we offer include excision of the lesion or injection of steroids directly into the chalazion or stye.
