Congenital Stationary Night Blindness
This is a degenerative disease of the retina seen in Briards and also in people. This inherited eye disorder principally affects the rod photoreceptors in the retina, impairing night vision. There may also be moderate to high myopia (short-sightedness).
Poor night vision in dogs.
This inherited eye disorder principally affects the rod photoreceptors in the retina, impairing night vision.
The disorder is diagnosed by electroretinography. Eventually it leads to blindness.
Veterinarians at Cornell University's College of Veterinary Medicine have used gene therapy to restore the vision to affected dogs. While gene therapy is certainly a hope for the future of individual dogs, it is still best to have a CERF (Canine Eye Registry Foundation) exam and use genetic testing to screen breeding dogs to prevent producing puppies with this defect.
It is important to certify all breeding stock and register all offspring with CERF or the GDC (the Institute for Genetic Disease Control in Animals).
Please contact your veterinarian if you suspect your pet may have this condition.
