Causes of Periorbital Cellulitis

Spread from a Local Infection

Injury to the Region

Based on the American Association for Pediatric Ophthalmology and Strabismus, periorbital cellulitis can be caused by the spread of an infection that originates in the sinuses situated near the nose. The bony tissues between the orbit and the sinuses are not very thick, so the infection can spread to the eyelid tissues. However, most cases of sinusitis do not cause periorbital infections. Bacteria that could cause this sort of illness include Streptococcus pneumoniae, Staphylococcus aureus and Haemophilus influenzae, based on EBMedicine.net.

Disease in the Blood

Bacteria in the abscess in the mouth can travel to adjacent tissues in the encounter. Bacteria involved in this sort of illness contain Bacteroides and Fusobacterium, based on Christopher S. Kennedy and Mary E. Moffatt in the 2005 novel "Harwood-Nuss' Clinical Practice of Emergency Medicine: 4th Edition."

Any trauma that breaks skin in the eyelid area can lead to peri-orbital cellulitis, as stated by the U.S. National Library of Medicine. A scratch to the eye lid or an animal or insect bite can allow bacteria to enter the tissues of the eye lid, causing an illness. wound that is modest may also lead to an infection. Bacteria that are generally situated on the skin, such as Staphylococcus aureus and Staphylococcus epidermidis, may function as the cause of these infections, based on EBMedicine.net. Careful observation of or eyelid injuries can stop direct infection and advance.
