Definition of Periorbital cellulitis:

Periorbital cellulitis is an infection of the tissues surrounding the eye.

Causes, incidence, and risk factors:

Periorbital cellulitis is most common in children under age 6.

It can be the result of minor trauma to the area around the eye, or it may extend from another site of infection, such as sinusitis.

Symptoms:

There is generally redness and swelling of the eyelid and the surrounding area. Unlike orbital cellulitis (a more extensive infection involving deeper tissue), periorbital cellulitis does not cause the eyeball to protrude (proptosis) or limit its movements.

Calling your health care provider:

Although periorbital cellulitis rarely has complications, any infection near the eye and close to the brain is potentially serious. It is important to call your doctor immediately if you think that you or your child may have periorbital cellulitis.
