DefinitionMost bumps on the eyelid are styes. A stye is an inflamed oil gland on the edge of your eyelid, where the lash meets the lid. It appears as a red, swollen bump that looks like a pimple. It is often tender to the touch.
Alternative NamesBump on the eyelid; Stye; Hordeolum
Causes, incidence, and risk factorsA stye is caused by bacteria from the skin that get into the oil glands in the eyelids that provide lubrication to the tear film. Styes a lot like common acne pimples that occur elsewhere on the skin. You may have more than one stye at the same time.Styes most often develop over a few days and may drain and heal on their own. A stye can become a chalazion -- this is when an inflamed oil gland becomes fully blocked. If a chalazion gets large enough, it can cause trouble with your vision.If you have blepharitis (see eye redness), you are more likely to get styes.Other possible eyelid bumps include:Xanthelasma -- raised yellow patches on your eyelids that can happen with age. These are harmless, although they are sometimes a sign of high cholesterol.Papillomas -- pink or skin-colored bumps. They are harmless, but can slowly grow, affect your vision, or bother you for cosmetic reasons. If so, they can be surgically removed.Cysts -- small fluid-filled sacs that can affect your vision.
SymptomsIn addition to the red, swollen bump, other possible symptoms include:A gritty, scratchy sensation as if there is a foreign bodySensitivity to lightTearing of your eyeTenderness of the eyelid
Signs and testsYour doctor or nurse can diagnose a stye just by looking at it. Tests are rarely needed.
To treat eyelid bumps at home:Apply warm, wet cloth to the area for 10 minutes. Do this four times a day.Do NOT attempt to squeeze a stye or any other type of eyelid bump. Let it drain on its own.Do NOT use contact lenses or wear eye make up until the area has healed.If the style is infection, your doctor may: Prescribe antibiotic creams Make an opening in the style to drain it (Do not do this at home)
Expectations (prognosis)Styes often get better on their own. However, they may return. The outcome is almost always excellent with simple treatment.Sometimes, the infection may spread to the rest of the eyelid. This is called eyelid cellulitis.
