What is orbital cellulitis?

Orbital cellulitis may be caused by inflammation of periorbital structures, direct infection of trauma, blood infection, etc.

1. Inflammation of periorbital structures spreading to

nasal sinuses, frontal sinuses, maxillary sinuses and sphenoid sinuses may cause orbital cellulitis; periodontitis and apicitis if not treated in time, may cause abscess on the anterior wall of maxillary sinuses, and upward to the orbit, may also cause orbital cellulitis.

2. Direct infection of trauma

patients after eyelid penetrating injury, if the wound is not properly treated, may be due to direct infection of purulent bacteria, forming orbital cellulitis.

3. Blood infection

Other parts of the body if there is suppurative focus, may migrate to the orbit through blood, thus causing orbital cellulitis.
