Frequently Asked Questions

What is the difference between periorbital and orbital cellulitis?

Orbital cellulitis refers to an infection of the eye tissues behind the orbital septum, which is membranous tissue that separates the eyelid from the eye socket. Periorbital cellulitis is also an infection of the eye tissue, however, it only affects the front of the orbital septum. On the other hand, orbital cellulitis spreads to the eye socket.

Another big difference between periorbital and orbital cellulitis is timing. While adults can get periorbital cellulitis, it’s more common among children who are under two years. Orbital cellulitis is more commonly caused by sinusitis, while periorbital cellulitis is commonly caused by trauma or barteremia.
