Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - A hordeolum is a localized abscess involving the glands of the eyelid. An external hordeolum (stye) involves an eyelash (cilia) follicle or the tear glands of the lid margin (glands of Zeis, Moll). An internal hordeolum involves the meibomian glands. S aureus is the most frequent isolate, although hordeola may be sterile. Clinical findings include focal swelling, edema, erythema, and tenderness.
