- An infection in another part of the body—like the sinuses or mouth
This infection is more common in children. Things that raise the risk are:
- Sinus or tooth infections
- Infection of the bloodstream
- Injury or surgery in the area

Orbital cellulitis can get worse fast. A hospital stay is often needed.
Medicines will be given, such as:

- Corticosteroids pills—to reduce inflammation, swelling, and pain
Pus may need to be drained. It may be taken from the sinus or eye area.
This problem may be prevented by treating sinus or dental infections right away. The Hib B vaccine may also help protect children.
