Infected Chalazion / Hordeolum: An Overview
Abstract
A hordeolum (or also stye) is an acute, localized bacterial infection of the sebaceous glands of the eyelid, either of the glands of Zeis (external hordeolum) or the meibomian glands (internal hordeolum). The condition presents as a painful, localized purulent infection of the sebaceous glands of the eyelid of either gland of Zeis (external hordeolum) or the meibomian glands (internal hordeolum). Conversely, an infected chalazion is a chronic, non-infectious, lipogranulomatous inflammatory lesion caused by ductal blockage of the meibomian gland, which changes an otherwise painless, firm lesion into an acute, painful lesion, which is tender, warm, and swollen, and which clinically simulates an internal hordeolum.
