−

~~===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.~~
