'''Orbital Cellulitis''' is an infection of the tissue surrounding the eye. If frequently localises and progresses to form '''Retrobulbar Abscesses'''.

'''Orbital Cellulitis''' is an infection of the tissue surrounding the eye. If frequently localises and progresses to form '''Retrobulbar Abscesses'''.

The aetiology is uncertain but assumed to be secondary to '''haematogenous spread''' or penetrating '''foreign bodies'''. '''Anaerobic''' culture is frequently required to produce any growth from samples. [[Pasteurella and Mannheimia species - Overview|''Pasteurella'']] has been grown from dogs with orbital cellulitis, whilst [[Aspergillus spp.|''Aspergillus'']] and ''Penicillium'' has been grown from cats.

'''Drainage''' should be attempted by making a stab incision through the oral '''mucosa''' caudal to the rear upper molar tooth, followed by careful blunt dissection to the orbit. Any exudate drained should be submitted for culture. The orbit should be gently flushed with sterile saline.

It is advisable to submit any exudate drained for culture. The orbit should be gently flushed with sterile saline and [[Antibiotics|broad spectrum antibiotics]] administered until culture results are received. Antibiotics should be administered for at least 7 days.

If clinical signs do not resolve or recur, further investigation or surgery should be undertaken to rule out foreign bodies. Persistent infection from the roots of upper molar teeth should also be ruled out.
