sty, stye

pl. sties pl. styes [AS. stigan, to rise]
A localized inflammatory swelling of one or more of the glands of the eyelid. They are mildly tender, and may discharge some purulent fluid.
SEE: chalazion

General edema of the lid, pain, and localized conjunctivitis mark the condition. As the internal sty progresses, an abscess will form that can be seen through the conjunctiva.

Applying warm, moist compresses to the eyelid several times a day for 4 or 5 days usually helps the sty drain. If the sty does not resolve, it can be incised and drained surgically.
SYN: SEE: hordeolum
