In-Depth

What is a hordeolum (stye)?

A hordeolum, more commonly known as a stye, is an inflammation of part of the eyelash. This condition is seen more often in children than in adults.

What causes a stye?

A stye is caused by an infection in the oil-producing sebaceous or sweat glands in the eyelid. The infection is usually caused by bacteria called Staphylococcus aureus.

What are the symptoms of a stye?

Each child may experience symptoms differently, but the most common symptoms of a stye include:

  • swelling of the eyelid
  • redness at the edge of the eyelid
  • pain over the affected area
  • tenderness

Because the symptoms of a stye may resemble other conditions or medical problems, you should always consult your child's physician for a diagnosis.
