If you notice that your dog's eyes are beginning to look cloudy, it may be a cataract forming. According to VCA Animal Hospitals, cataracts do not necessarily mean a dog is blind. When cataracts account for less than 30 percent of the eye's lens, your dog can most likely still see just fine. Once the cloudiness has taken over more than half of the lens, chances are that your pet's vision will begin to be obstructed. Eye cloudiness can also be a benign aging change—called nuclear sclerosis—which does not significantly impair vision.
VCA reports that cataracts can be successfully removed and this surgical procedure is usually performed by board-certified veterinarians in ophthalmology. To determine if your dog is a candidate for cataract surgery, many specialized eye tests will be performed to make sure their vision is likely to return with the removal of the cataract.
Cataracts can form for many reasons, but typically they are genetically inherited. Cataracts can also be caused by ocular injury or diseases like canine diabetes—also called diabetes mellitus or sugar diabetes. The most common clinical signs of this condition include cataracts as well as increased thirst, frequent urination, and increased appetite paired with weight loss.
If you notice that your dog's eyes are growing cloudy, you should schedule an appointment with your vet to assess the situation and determine the most appropriate treatment for your furry friend.
