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.
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 () or limit its movements.
