- Canine cataract is the breakdown or disruption of the normal arrangement of the lens fibers or it's capsule. The disruption results in the loss of transparency which causes a reduction in vision and even blindness. The only real and proven treatment, is surgery. Cataracts in the lens of the eye look white, cloudy, or have a "crushed ice" appearance.
- Nuclear sclerosis is a more common condition which is a normal change that occurs in aging dogs. Nuclear sclerosis appears as a slight graying of the lens. It usually happens in both eyes at the same time and occurs in most dogs after the age of 6 years. The loss of transparency occurs because of the compression of the linear fibers in the lens. Unlike cataracts, Nuclear sclerosis doesn't really interfere with your dogs vision. They usually don't recommend treatment.
If your dog has either, talk to your vet about which one it is likely to be before you use any over the counter treatment. You could do more damage than good. Always, always, consult your Vet.
