What is a stye (hordeolum)?
A stye (or hordeolum) is an infection that occurs within the eyelids. A stye usually begins as a subtle irritation of the eyelid, or a foreign body sensation on the eye. Close inspection will usually reveal a small red spot on the eyelid. As the infection continues, the stye will become a painful, red lump, causing the eyelid to become swollen. Eventually, the swollen nodule may form a pustule, and drain. If the stye does not resolve, the nodule may harden as the infective debris solidifies. A stye results from blockage of one or more of the small oil producing glands (meibomian glands) that are found in the upper and lower eyelids. These blockages trap the oil produced by the glands and cause a lump on the eyelid that is usually about the size of a pea. Bacteria that exist normally on the eyelid also become trapped in the gland, and begin the infective process. Treatment of styes involves persistent hot compress application. Antibiotic drops, ointments, or other topical applications a
