We had it with a Kerry Blue once, after he'd had a rumpus with another - that was definitely caused by trauma to the neck.
I used a lot of homeopathy on him - it was before the days of MRI scans etc. If you PM me, I can try to remember what I used - it did (or something did) help the dry-eye type symptoms, and he looked much more normal, but always used to trot round in circles as if he were lunging himself on a line!
