Description An external stye starts out as a small round spot next to an eyelash. Then, it turns into red painful swelling. It lasts a few days and then bursts and heals. An internal stye can leave a cyst or nodule that usually needs drained.

Scientific Description Affects the eyelid area

Internal Stye 2 Styes External Stye

Symptoms Redness, swelling, pain, or tenderness in part of the eye. Usually accompanied by blurred vision, tears, and the feeling of something in the eye.

Staphylococcal bacteria Causes An eye stye is caused by staphylococcal bacteria. An infection of an eyelash follicle, apocrine gland, or sebaceous gland (which produces an oily substance called sebum that lubricates the eyelash to prevent it from drying out) also causes a stye. Staphylococcal bacteria

Cure Use a warm cloth several times every day until the stye clears up. Keep the area around your eye clean. If the stye persists, a doctor may remove the eyelash close to the stye or use a needle to drain it.

Worst Case Scenario Vision may become blurry Stye lasts for several weeks when untreated Cosmetic deformity In rare cases, an infection can occur. It very rarely spreads throughout the body. Surgical removal

Facts Styes can be prevented by: removing eye makeup daily, disinfecting contact lenses, and cleaning eyes everyday. Chalazia are the result of a chronic stye when the inflammation runs its course but the painless bump remains.  Styes are very common. People of all ages can develop a sty, and men and women are equally affected.
