Cone-rod dystrophy 2 is an inherited eye disease that affects the retina, which is the light-sensitive tissue at the back of the eye. In this condition, the specialized cells called photoreceptors—specifically the cones for daylight vision and the rods for low-light vision—degenerate prematurely. This progressive breakdown leads to an irreversible loss of sight.
Owners may first notice their puppy struggling to see or bumping into objects in bright light, with symptoms appearing as early as 10 weeks of age. The condition progresses rapidly, typically resulting in complete blindness by one year of age.
There is no cure or treatment to stop the progression of this painless condition. Lifetime costs generally range from 300 to 1500 EUR, which covers the initial veterinary ophthalmologist diagnosis and minor home safety adaptations to help the blind dog navigate safely.
