Overview

Orbital cellulitis is a serious infection of the orbital tissues which can lead to restriction of eye movements, loss of vision and even loss of life. Orbital cellulitis is an inflammation of eye tissues posterior to the orbital septum. It most commonly refers to an acute spread of infection into the eye socket from either the adjacent sinuses or through the blood. When it affects the rear of the eye, it is known as retro-orbital cellulitis.

It should not be confused with periorbital cellulitis, which refers to cellulitis anterior to the septum.
