The best treatment is to apply hot compresses for 10 minutes several times a day. The warmth helps the stye come to a head, rupture, and drain. When a stye forms in one of the deeper glands of the eyelid, a condition called an internal hordeolum, the pain and other symptoms are usually more severe. Pain, redness, and swelling tend to occur in just a very small area, usually at the edge of the eyelid. Because this type of stye rarely ruptures by itself, a doctor may have to open it to drain the pus.
Internal styes tend to recur.
Chalazion A chalazion is an enlargement of a long, thin oil gland in the eyelid that results from an obstruction of the gland opening at the edge of the eyelid. However, after a few days the symptoms disappear, leaving a round, painless swelling in the eyelid that grows slowly for the first week. A red or gray area may develop underneath the eyelid. Most chalazions disappear without treatment after a few months. If hot compresses are applied several times a day, they may disappear sooner.
