A stye which is sometimes called a hordeolum on the eye occurs when a gland on the eyelid becomes infected. This can occur on the inside or outside of the eyelid and looks like a spot or pimple.
Symptoms of a stye
Symptoms include tenderness on the eyelid with redness and swelling. A small head may appear on the swelling like a spot or pimple. Sty's usually appear at the base of the eyelashes. There may be some minor visual impairment. Sty's on the inside of the eyelid feel like there is something stuck in the eye.
A stye is an infection of an oil gland caused by staphylococcal bacteria. The infection usually occurs from rubbing the nose and then the eye. The bacteria involved are most often found inside the nose.
In most cases a sty will heal on its own within a week. Don't ever try to squeeze a sty. They may just disappear on their own, or they may rupture and then clear. Stys on the inside of the eyelid may not heal or may be irritating in which cases an ophthalmologist (eye specialist) may drain the sty for you.
