Crawford Dogs Posted March 31, 2013 Report Share Posted March 31, 2013 My Border Collie Rose has seemed a bit off for a few months. Toys and treats thrown off her usually bounce of her head instead of being caught, she's run into a few more trees and my parked car, and seems to be getting lost on the agility course- unable to find obstacles and me on occasion. Finally I took her into the opthamologist thinking that they'd say she had some minor cataracts or simply wasn't paying attention (because Rose is a rescue I have never been able to do annual CERF's like I do on my other dogs-- the vet charges twice the price to see a non-papered dog). Instead the vet said she had an early stage of Immune Mediated Retinopathy (IMR). He showed me that Rose had no pupillary light reflex (plr) to some colors of lights but had normal response to other lights (different wavelengths?). They ran an ERG and a multitude of other tests. I was told that either I could give her immunosuppressive drugs or she would go completely blind. Rose starts the drugs next week. Has anyone else run into this issue with their Border Collies? IMR is supposed to be very similar to and hard to differentiate from SARDS (Sudden acquired retinal degeneration syndrome?). Also, Rose is supposed to avoid Ivermectin-based heartworm preventatives and do titers instead of vaccinations for the rest of her life. The vet said that vaccinations can worsen the disease and cause sudden blindness in the affected dogs. AND, the annual CERF doesn't test for these diseases so even if Rose had gone in for annual CERF's they wouldn't have caught the disease.
