StyeA sty generally results from an acute infection of the oil glands of the eyelid – meibomean glands - that occurs after these glands have become clogged. A sty also may arise from an infected hair follicle at the base of an eyelash. The bacterium Staphylococcus Aureus is responsible for 90%-95% of cases of styes. A sty can develop as a complication of blepharitis (inflammation of the eyelid). The first symptoms of a sty are generally redness, tenderness, and pain in the affected area. The eye may feel irritated or "scratchy." Later symptoms can include swelling, discomfort during blinking of the eye, watering of the eye, and sensitivity to light. A common sign of a sty is a small, yellowish spot at the center of the bump that develops as pus expands in the area. Styes are very common. People of all ages can develop a sty, and males and females are equally affected. People with certain chronic conditions (diabetes mellitus, chronic blepharitis and chronic debilitating illnesses) are more prone to developing styes than the general population. In many susceptible people, stress seems to trigger the development of a sty. Studies have shown that those who have high levels of blood lipids are more susceptible to blockages in the oil glands, including those of the eyelid and, therefore, are more likely to develop a stye.
