A range of conditions can affect the orbit.
==Conditions==
===Developmental===
Shallow orbit (brachycephalic breeds)
Micropthalmia/Anaopthalmia
===Trauma===
Penetrating foreign bodies
[[Exophthalmos_-_Canine|Proptosis Of The Globe]]
===Infections===
Orbital Cellulitis and Retrobulbar Abscesses
===Neoplasia===
Orbital Neoplasias
===Miscellanous===
[[Salivary_Mucocele|Zygomatic Mucocele]]
Eosinophilic Myositis
Horner's Syndrome
==Diagnostic Investigations==
===Palpation===
Placing pressure through the eyelids can help determine the location and contents of the globes.
===Oral Examination===
In the presence of '''exopthalmos''', pain on opening the mouth indicates an '''inflammatory''' process, whilst no pain indicates a '''neoplastic''' process. Where possible the soft tissue caudal to the rear upper molar should be palpated.
===Ultrasound===
Useful for evaluating soft tissue masses
===MRI/CT===
Useful for localising lesions, surgical planning and FNA/biopsies where appropriate.
