Plain-English summary
A 5-year-old mixed-breed dog was brought in because it was having trouble moving its legs and had decreased responses in both eyes. An eye exam showed that while the dog could still see, there were significant issues with the optic nerves and the back of the eyes that looked similar to a condition called Collie eye anomaly (CEA). Unfortunately, despite treatment, the dog's condition continued to decline, and it was ultimately euthanized. Further tests revealed that the dog also had lymphoma affecting the spinal cord, but the eye problems were not related to this cancer.

Abstract
A 5-year-old, mixed-breed dog was presented for tetraparesis. Neurologic alterations included a decreased menace response in both eyes. Therefore, an ophthalmic examination was requested. The dog was visual, but menace response, dazzle and pupillary light reflexes were reduced bilaterally. Indirect ophthalmoscopy revealed bilateral optic nerve coloboma and severe choroidal hypoplasia. These lesions closely resembled the ophthalmoscopic features of Collie eye anomaly (CEA). In spite of treatment, the dog's condition worsened and the animal was therefore euthanized. Histology of the globes confirmed severe choroidal hypoplasia and optic disc coloboma in both eyes. The dog was diagnosed to have a lymphoma involving the spinal cord. The two entities were considered not related. As only moderate sight impairment was caused by the posterior segment anomalies, it is by chance that these lesions resembling CEA were found in this mixed-breed dog.
