What is a cataract?
Inside the eye is a lens that focuses light on the back of the eye
or the retina. Vision occurs at the retina. This is similar to a
camera which has a lens to focus light on the film. If the lens
becomes opaque this is called a cataract.
What causes cataracts?
most common cause of cataracts in the dog are inherited. Other
causes include injuries to the eye or diseases such as diabetes
mellitus (“sugar diabetes”). Some appear to occur spontaneously and
are age related.
some breeds more prone than others?
Many breeds of dogs are affected with hereditary cataracts. Some of
the recognized breeds include the American Cocker, Labrador, Poodle,
Boston Terrier and the Welsh Springer Spaniel to mention a few.
my dog go blind?
cataracts occupy less than 30% of the lens or only one lens is
affected, they rarely cause diminished vision. When the opacity
reaches about 60% of the total lens area, vision impairment is
usually apparent. If the opacity progresses to 100% of the lens, the
dog is then blind. However, whether the cataract remains static or
progresses depends on the type of cataract, the breed and other risk
anything be done to prevent my dog from going blind?
Today’s veterinary ophthalmologists can remove cataracts and
restore failing vision in your pet. Most pets have few complications
and return to normal running and playing within just a few days of
old will my dog be if he does go blind? Since
the major cause of cataract is hereditary, cataract progression
varies from breed to breed. In some breeds cataracts will develop
relatively early in life whereas in others the first signs are
detected when the dog is older and progression is so slow that dogs
still have reasonable sight well into old age.
the condition is hereditary, what can be done to prevent it from
being passed on?
is a situation where prevention is better than cure. Many
organizations offer eye disease certification programs that offer
breeders an excellent chance to make sure they are producing disease
free puppies. We will be more than happy to discuss details with
