What is the definition or description of: stye?

Plugged oil gland: Styles are blocked or plugged up oil glands in the eye lids. We call these chalazion. Best treated by warm compresses 4-6 times a day foe ten minutes, for many weeks. If large this can be drained as a minor procedure in the office, rarely in an operating room.

Inflamed oil gland: A stye is an acutely inflamed meibomian or oil producing gland in your eyelid. Many times styes are successfully treated with warm compresses to help the blocked gland drain naturally.

Clogged oil gland: A sty is when an oil gland of the eyelid margin gets clogged and the oil backs up and forming a pocket of stagnant oil and the eyelid becomes inflamed. A hordeolum is the acute phase or beginning stage of a stye, and a chalazion is the chronic phase (where the oil becomes more granular, thick and the skin inflammation resolves, but there is still a bump/nodule in the eyelid).
