Hordeolum or Stye

Is a small boil seated at the edge of the eyelids and involving a Meibomian gland. It is not an active kind of boil, but progresses sluggishly, the pustule centre being small. It is painful, and some time lapses before all traces of its existence go. There may be one, two, or more on one or both eyelids. Some persons are subject to repeated outbreaks of this furuncular inflammation. We find it most frequently in youthful individuals of rather delicate health with a tendency to acne, or in persons addicted to free living or dissipation. If by frequent relapses it induces inflammatory changes in the Meibomian glands, and is followed by fatty or chalky degeneration of their contents, it is called Chalazion.
