Cataracts appear as gray to white areas in the lens. Surgical removal of the cataract is the only effective treatment. This is usually done by a veterinary ophthalmologist on a referral basis. The surgery is highly effective in most patients. Cataracts must not be confused with sclerosis of the lens.
Lenticular sclerosis is a normal age-related change in the canine eye.
As the dog ages the interior portion of the lens becomes harder and more compact, producing an indistinct grayish-blue haze. Your veterinarian can easily distinguish cataracts from lenticular sclerosis with an ophthalmascope. Lenticular sclerosis does not interfere with vision and does not require any treatment. Please remember that any indication of an eye problem is cause for an examination by your veterinarian. Some ocular diseases can threaten your dog's vision, and prompt intervention is necessary.
