Cataracts

Cataracts are one of the most common eye problems in dogs, and they show up in canines of all breeds and in animals both young and old. As with humans, the only successful treatment is surgery.
The word "cataract" literally is Latin for "break down," and refers to a problem that develops with the fibers in the lens of the eye. The disruption of these fibers causes the lens to become cloudy, reducing vision. There are several types of cataracts, which have different causes. All, however, result when the biochemistry of the eye (66 percent water and 33 percent protein), becomes out of balance. The end result is that too much water remains in the lens of the eye, while the percentage of insoluble proteins increases. The combination causes the cloudy white coating, loss of transparency and loss of vision characteristic of cataracts. [...]

In a normal eye the lens is clear and translucent, the better to perform its job of transmitting and focusing light onto the retina in the back of the eye. When disease, aging, or injury clouds and/or damages this lens, a variety of vision-related problems can occur.
One commonly recognized form of lens opacity is a cataract, which causes a cloudy film to gradually grow over the lens, obscuring vision. Most cataracts in dogs are genetically related. How old the dog is when cataracts appear and how severe they become depends largely on what type of breed is affected. [...]

Cataracts are one of the most well-known forms of eye disease, appearing as a cloudy or opaque spot that changes the lens of the eye and causes it to lose its translucence. Cataracts may be limited to a small section of the lens, or they may grow to affect the entire eye. Cataracts also can strike one or both eyes, depending upon the cause. If left untreated, cataracts inevitably end up costing the dog its sight.
Many breeds are prone to inherited cataracts, which can be passed along through both dominant and recessive genes. Inherited forms result in what are known as primary cataracts. [...]

All dogs have health problems, whether hereditary or acquired. Compared to other breeds, the Norwegian Buhund is considered a naturally healthy breed. Because it is a hardy breed with good resistance against diseases, it does not get ill as often as other dogs.
One of the basic measures to ensure the health of your Norwegian Buhund is regular checkups at the vet. You should bring your dog for vaccination and health tests once a year. A Buhund is prone to ear and eye infection, but if you check its eyes and ears regularly, such illnesses can be easily taken care of. [...]

Overall the Tibetan Terrier is a healthy dog with few health problems associated with their stock. Yet, there are a few that need to be monitored for including their eye problems. The dogs can develop cataracts and in fact these are sometimes common in the dogs as they age. The cataracts that they have are often the same as you would see in a human cataract situation. Yet, for dogs that can not tell you what is wrong, it is up to the owner to pay close attention to these dogs and the quality of eyesight that they have. There are also several other types of eye conditions that can affect your Tibetan Terrier and that you can monitor them for. [...]

Most aging dogs will experience a decrease in both their visual as well as hearing abilities. When this loss occurs slowly, the dog is actually able to adapt and increase his or her dependence on the other senses to balance out the loss of vision or hearing. In this way an elderly dog can easily live a very happy and relatively normal life even with complete hearing or vision loss. Of course there are some modifications that owners need to make, especially with regards to safety issues for these dogs, but there is no need to feel sorry for your dog or believe that they feel the loss of these senses the same way that humans would.
