If you dog does not seem to see well anymore, if he told everything in its path and
run into his pupil is not black, but whitish, then the chances that your dog has
cataract or cataract-very large.
What is cataract?
In the eye of the dog is a flexible
lens that can change shape to the light as it should on the retina to focalization.
In this way the dog views as to adjust the various objects to identify cross his
path and the objects that are farther away. To be able to see perfectly, the crystalline
lens totally transparent. But as a dog ages, the crystalline lens thickens and age
making it increasingly cloudy. The pupil of the hondenoog, usually black in color,
then shows bluish reflections and then more and whiter. As this process progresses,
the dog gradually reduced vision and blind. That in itself is a normal phenomenon,
but sometimes that is not. This is the case when the crystalline lens thickens at
The causes of cataract
The most common cause of cataracts in dogs is the
aging of the crystalline lens when the pet reaches an older age. The disease evolves
slowly, it may take several months to years, but mostly cataract begins at the age
of seven to nine years. Cataracts can however also occur in young dogs from six months
to one years. In that case, hereditary cataracts and certain dog breeds have often
prone than others: Afghan Hounds, American cockers, German Schepers, Siberian huskies
and poodles. Other races have sometimes suffer from hereditary cataract, which is
present at birth, as the Boston Terrier and the Westie. This type of cataracts usually
affect only one part of the crystalline lens. Cataracts can also occur with poorly
controlled diabetes if diabetes-in which the glucose in the blood for a high-glucose
concentrations increased near the eye makes. This is expressed by the transformation
of glucose to sorbitol in which the crystalline lens to become cloudy. This type
of cataract occurs very rapidly. Finally, trauma or severe inflammation may also
result in a more cloudy lens.
The treatment of cataract
In older dogs with cataracts,
the age evolution of the disease delayed by a syrup containing amino acids. The only
effective treatment for cataracts is surgery, however, but that is rarely presented
in older dogs because the operation often complications occur and because the dogs
have a comfortable life can lead to cataract, even if they are less able to see.
In younger dogs, the treatment consists of addressing the cause to ensure that the
disease evolves. Hereditary cataract finally can sometimes spontaneously disappear
so that the dog has a nearly normal vision. Cataracts in puppies can move when the
lens grows so the dog as an adult has normal vision.
