Definition of Eyelid bump
Most 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 tender, especially to the touch.
Causes, incidence, and risk factors
A 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 are similar to common acne pimples that occur elsewhere on the skin. You may have more than one stye at the same time.
Symptoms
In addition to the red, swollen bump, other possible symptoms include:
Signs and tests
A doctor can diagnose a stye just by looking at it. Special tests are usually not necessary.
Expectations (prognosis)
Styes often get better on their own. However, they may recur. The outcome is generally excellent with simple treatment.
