(Hordeolum)
A sty develops when a pimple like abscess forms in one or more of the specialized oil glands that line the eye-lid. The term sty (or Stye, as it is some times spelled) derives from the old English word "stigend", which means "to rise" Hordeolum, the medical term for a sty, is Latin for "a small grain of barley", which describes its appearance.
Most sties develop at the base of an eyelash on the outside of eyelid, but some, called internal hordeola, form on the inner edge. Regardless of where they appear, sties are usually caused by Staphylococcal bacteria, organisms that normally live on the skin n in the nasal passages without causing harm..
TREATMENTS: Most sites can be handled with self treatment, but medical care is warranted if a sty fails to rupture or doesn't drain spontaneously after it bursts.
When a sty doesn't burst or drain, it may be opened with a fine tipped lance, allowing a doc to express its contents. To prevent recurrence, an antibiotic ointment/cream may be applied.
