Primary orbital neoplasias are uncommon in dogs and cats.
==Types Of Tumour==
[[Central_Nervous_System_Neoplasia|Meningioma]] is the most common primary tumour in dogs. It is a benign slow growing tumour that if untreated causes pressure atrophy.
Other tumours described include [[lymphosarcoma]], [[adenocarcinoma]], [[fibrosarcoma]], [[Multilobular_Tumour_of_Bone|multilobular ostersarcoma]], glioma, myxoma, [[Squamous_Cell_Carcinoma|squamous cell carcinoma]], rhabdomyosarcoma and canine lymphoid pseudotumour.
==Clinical Signs==
Unilateral progessive painless '''exopthalmos'''
Prominent protruding '''third eyelid'''
'''Blindness''', though not in all cases
'''Exposure keratitis''', secondary to the exopthalmos
Retinal folds or retinal detachment on opthalmoscopic exam
Nasal discharge
Dilated/eccentric pupil
==Treatment==
Surgical exploration and removal of the globe and associated orbit contents is recommended.
Depending on the type of tumour chemotherapy or radiation therapy may be appropiate.
