A hordeolum is a common disorder of the eyelid. [1] It is an acute focal infection (usually staphylococcal) involving either the glands of Zeis (external hordeola, or styes) or, less frequently, the meibomian glands (internal hordeola). [2]

"Hordeum" is Latin for barley, the appearance of which a hordeolum can resemble.
