    Surrounding the follicles at the base of the eyelashes are oil glands, which, when obstructed, produce a hordeolum, or stye. A hordeolum may look like a pimple and develops near the skin surface on the anterior margin of the lid, adjacent to the cilia. Hordeola with swelling only are usually not infected, although redness and discomfort may be signs of infection.
