Cataracts in Dogs

One of the most common problems that affect aging dogs is cataracts. There are several different causes that contribute to cataract formation, as well as different forms. All breeds of dogs are can form cataracts, but some breeds tend to be more susceptible to them. Currently, the only treatment option available is surgery.

What are Cataracts

The meaning of the word cataract is literally “to break down.” A cataract causes a disruption of the normal arrangement of the lens fibers or its capsule. There is a loss of transparency due to the disruption and a reduction in vision. Cataracts are found in the lens of the eye and many times appear to have a white or crushed ice appearance.

How Cataracts Form

Regardless of the form or cause, all cataracts develop in a similar manner. The normal lens of the eye in maintained in a dehydrated state, meaning that it consists of 66% water and 33% protein. A very sensitive pump keeps this water/protein balance in check. In the event that the biomechanical system is damaged, the pump begins to fail and allows extra water into the lens. At the same time, the percentage of protein increases. All of these changes result in the loss of transparency and cataract formation.

When They Form

The age at which a dog develops cataracts is very critical when classifying what type of cataract the dog is suffering from. This helps to determine if the cataracts are the result of a hereditary trait in certain breeds of dogs.
