If your dog has nuclear sclerosis, also commonly referred to as lenticular sclerosis, rest assured that this diagnosis is both very common, and will not have a noticeable impact on your dog’s health or movements. What is most important is that your dog will not experience pain as a result of this condition. In fact, getting this diagnosis is basically just confirmation of your dog’s age, since nearly all dogs will develop nuclear sclerosis after the age seven.

Causes of Nuclear Sclerosis in Dogs
Your dog’s nuclear sclerosis is an eye condition which develops as a result of the physiology of the eye. It’s a natural process for tissue to be added within the lens of a dog’s eye. Since there is finite space within the lens of the eyes, as these layers of tissue build up they cause the formerly translucent appearance of your dog’s eyes to shift into an opaque blueish-gray. This transformation does not affect the dog’s vision, and occurs in nearly all dogs starting around age six or eight. It’s also important to note that this is a purely cosmetic shift, and does not cause your dog any pain.
Symptoms of Nuclear Sclerosis
The main symptom of nuclear sclerosis in your dog is the appearance of their eyes: rather than a clear lens, the lens will turn opaque and be a blue-gray color. This will happen to both eyes simultaneously. Because the eyes look cloudy, which is a similar symptom to cataracts, you may feel concerned when you notice this change in your dog’s eyes -- a trip to the vet will help confirm what’s behind the blue-gray appearance of your dog’s eyes. As dogs get very elderly, it’s possible that nuclear sclerosis will cause an impact on their vision, making it difficult to see things that are far away. The impact is generally minor.
Diagnosis and Treatment
You may possibly think that the changed appearance of your dog’s eyes is due to conditions such as cataracts or glaucoma. Since these conditions have a more serious lifestyle impact, and often require treatment, it’s a good idea to take these symptoms seriously and have your vet investigate the causes for the changed appearance in your dog’s eyes. This is particularly recommended if the change only occurs in one eye, since nuclear sclerosis occurs simultaneously in both eyes. In order to diagnose nuclear sclerosis, your vet will need to examine your dog’s dilated eyes. In some cases, a visit to a specialized dog opthamologist may be necessary.
This age-related condition is not preventable, and since nuclear sclerosis does not cause your dog pain, and also does not cause any major impact on a dog’s lifestyle, no treatment is required.
