Cataracts happen because the lens of the eye has become opaque or cloudy. The lens of the eye focuses light on the back of the eye (retina). The retina is where vision occurs. Cataracts are commonly an inherited disorder. Some of the affected breeds are Cocker Spaniels, Labrador Retrievers, and Boston Terriers. People interested in breeding a dog(s) that may be more prone to this disease should have him/her evaluated by a veterinary ophthalmologist. This way they can make sure they will produce puppies that won’t develop this condition, and the pet can be certified. Cataracts can also be caused by eye injury or underlying metabolic disease (diabetes). Some pets spontaneously develop them in old age. Development and progression of cataract formation varies from individual to individual. Those with a hereditary condition may have them appear at a young age. A pet’s vision depends on the severity of the cataract(s). If less than 30% of the lens is occupied, or only one eye is affected, sight is rarely diminished. When 60% of the lens is opaque, visual impairment is noted. The pet is blind if 100% of the lens is cloudy. Cataracts can be removed by a veterinary ophthalmologist. Your regular veterinarian can refer you to a specialist if your pet has cataracts and you are interested in the procedure. Tests will be done to make sure the surgery would restore vision. These include checking for electrical activity in the eye and uveitis (inflammation in the structures of the eye). There are risks involved and possible complications to be aware of (just like with any procedure), but most pets do quite well. Opting to do the surgery requires a financial commitment from the owner, as well as dedication to patient care. A pet parent must be willing to medicate their dog for weeks to months, and make several follow up visits for the best chance of a complete recovery.
