Cataracts in Dogs

By Admin

What are cataracts?  Cataracts in dogs are one of the most common eye problems for dogs.  A cataract is a loss of the normal transparency of the lens of the dog’s eye.  A spot on the lens that is opaque is technically a cataract.  Some cataracts can be seen by the naked eye as appearing as white flecks within the eye, or giving a milky or bluish white cast to the lens behind the pupil.

The most common cause of cataracts is hereditary.  It is hard to tell the difference in hereditary and nonhereditary cataracts soley from the appearance of the lens.  Line history and breed predisposition are more suggestive.  If your dog has cataracts, then his offspring will have the possibility of having cataracts.  Hereditary cataracts commonly are commonly seen in Cockers, Poodles, Boston Terriers and Wirehaired Fox Terriers.

Cataracts are more likely to develop in diabetic dogs.  You should recognize the possibility of diabetes before considering cataract extraction.  The cataract operation is more likely to be successful, if the diabetes is controlled.

Old age cataracts are more common.  Most dogs that are eight years and older have some degree of haziness in their eyes.  Even if you see an opaque color to the eye, a considerable amount of useful vision may be retained.  Cataracts can cause blurry vision or blindness if left untreated.

You should only worry about the cataract when it causes impaired vision.  By removing the lens, which is cataract extraction, blindness can be corrected.  This restores the dogs vision.  There is some loss of visual activity, because the lens is not present to focus the light on the retina.  If the dog’s vision impairment is so bad that he has difficulty getting around, then a cataract operation is recommended.

Treatment of dog cataracts involves two options.  The first option is cataract surgery and the second is use of a special cataract eye drop to cure cataracts.
