A common staphyloccal infection of the lid glands; essentially an abscess, with pus formation; symptoms include swelling, redness, and pain. Two types are classified: internal hordeolum (relatively large, affecting the meibomian glands; may point toward the skin or toward the conjunctive) and external hordeolum (also known as a "sty;" smaller and more superficial; an infection of the glands of Moll or Zeiss; painful; always points toward the skin side of the lid margin). Both types of hordeola are treated with warm compresses for 10-15 minutes 3-4 times a day; if the condition does not improve within 48 hours, incision and drainage of the pus is indicated. Antibacterial ophthalmic ointment is also helpful. A large internal hordeolum has the potential to affect the entire lid through accompanying cellulites. Personal hygiene, especially for children, is an indication. If hordeola are frequently recurrent or associated with blepharitis, treatment with oral tetracycline may be utilized.
