Figure 1.6.3 Trauma with Proptosis (Canine) CT
3y FS Brittany Spaniel with acute head
trauma of unknown cause. Transverse images
are ordered from rostral to caudal. The globe
is located cranial and lateral to the orbit (a).
There is soft‐tissue swelling within the orbit
(b: asterisk), likely due to hemorrhage and
edema. The optic nerve appears enlarged and
surrounded by hypoattenuating tissue as it
crosses this region (b: arrow).

Figure 1.6.4 Anterior Uveitis (Canine) MR

(a) T1, DP (b) T2, DP (c) T1+C, DP
1y M Labrador Retriever with progressive swelling and cloudiness of the right eye. Glaucoma and uveitis were diagnosed following a
complete ophthalmic examination. There is increased signal intensity of the right anterior chamber on T1 images (a: arrow) compared to
the normal eye. There is a similar but more subtle increase in vitreous attenuation in the same eye. On contrast‐enhanced images, there
is marked enhancement of the fluid in the anterior chamber (c). The eye was enucleated after a corneal rupture, and plant material was
found within the lens capsule.
