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. [1] It may be caused by breaks in the skin around the eye, and subsequent spread to the eyelid; infection of the sinuses around the nose (); or from spread of an infection elsewhere through the blood.
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.
Orbital septum acts as a physical barrier that prevents the infection of the anterior part of the eye spreading posteriorly. For example, preseptal cellulitis mainly infects the eyelids, anterior to the orbital septum. Meanwhile, orbital cellulitis is located posterior the orbital septum, due to infections spreading from the ethmoidal sinuses.

The legs and face are the most common sites involved, although cellulitis can occur on any part of the body. [1] The leg is typically affected following a break in the skin. [1] Other risk factors include obesity, leg swelling, and old age. [1] For facial infections, a break in the skin beforehand is not usually the case. [1]
Periorbital cellulitis – An inflammation and infection of the eyelid and portions of skin around the eye. Blepharochalasis – An immune-mediated inflammation of the eyelid that is characterized by exacerbations and remissions of eyelid edema which results in a stretching and subsequent atrophy of the eyelid tissue, leading to the formation ...
Fascial spaces (also termed fascial tissue spaces [1] or tissue spaces [2]) are potential spaces that exist between the fasciae and underlying organs and other tissues. [3] In health, these spaces do not exist; they are only created by pathology, e.g. the spread of pus or cellulitis in an infection.
