A. The condition you are describing is called ventral or dorsal strabismus (deviation of the pupil either up or down, out of position). This is often associated with lesions or inflammation of the cranial nerves that lead to the eye (CN III). The best course of action is to take your pet to your local vet for a complete eye exam. An ophthalmologist may be needed to help figure things out. If inflammation is found to be a likely cause and preliminary bloodwork shows no signs of elevated WBC's or weakened immune system they may go ahead an start your pet on a trial of steroids to see if there is a response. Only because there are much more involved testing that are required to localize any other causes of this, which include expensive testing such as an MRI or CT scan.
So an initial bloodwork panel and steroids may be the most conservative first approach to trying to resolve this abnormality.
