A chalazion is an eyelid nodule, often mistaken for a large stye, which occurs due to a blocked oil gland. Chalazia can be small or large, inflamed or non-inflamed, tender or non-tender. They tend to resolve spontaneously after several days or weeks, and often respond well to warm compresses. Sometimes these lesions can be persistent and bothersome, in which case they can be treated by either administering a steroid injection, or by incision and drainage under local anesthesia. Both of these procedures can be performed with minimal discomfort in our office minor-surgery room by our highly experienced physicians.
