Orbital cellulitis is inflammation of eye tissues behind the orbital septum. It is most commonly caused by an acute spread of infection into the eye socket from either the adjacent sinuses or through the blood. It may also occur after trauma. When it affects the rear of the eye, it is known as retro-orbital cellulitis.
The affected eye may have increased tears or be "stuck shut" in the morning. [1] Swelling of the sclera may also occur. [1] Itching is more common in cases due to allergies. [3] Conjunctivitis can affect one or both eyes. [1] The most common infectious causes in adults are viral, whereas in children bacterial causes predominate.
Periorbital cellulitis, or preseptal cellulitis, is an inflammation and infection of the eyelid and portions of skin around the eye anterior to the orbital septum.
