dry eye syndrome

Sometimes, the infection disappears quickly, without forming into a red swelling. But other styes worsen rapidly until the eyelid swells up. Eye sty occurs when staphylococcal bacteria infect one of the tiny glands at the base of the eyelid hairs and then becomes inflamed. It is commonly found as small bumps on the base of eyelids.

Stye is often accompanied with certain complications, such as there may be spread of infection to other eyelash follicles. There may also be spread of infection to the tissue of the eyelid, which is known as Eyelid cellulites. The symptoms of styes may resemble other conditions or medical problems.
