With the improvement of people's living standards, pets began to enter each family, and gradually became a family member from the identity of small animals. In recent years, the problem of cataract on dog eye diseases has also frequently appeared in front of pet doctors. Because cataracts are one of the main reasons for the blindness of dog blindness, dog white internal barriers have to be valued.

Medically, when the lens sac or crystal is turbid, it is defined as cataract, and all kinds of animals can occur. Cataracts are more common in human medicine. In our country, it is the second ophthalmological disease with blind rates, but it is also a more likely cure ophthalmological disease. In the field of veterinarian, there are relatively little introduction and understanding of the disease.

There are many ways to classify cataracts. They can be classified according to the maturity, cause, location, shape, or occurrence of time of cataract, or overlap each other. More common is the two classification methods of maturity and cause.

maturity classification method

If the maturity is divided, cataracts can be divided into initial, development, maturity, bulging period, ultra -mature period, Morgagnian stage (also divided into four periods, development period, maturity period, and ultra -mature period).

1. Initial

It is less turbid and does not completely hinder light entering the retina, which has little impact on vision.

2. Development

Mature than early stage, vision recession but not completely hindered light to enter the retina.

3. maturity period

Fully hinders light into the retina, which can be seen in opaque white.

4. Break -up period

Crystal fiber is enlarged, and the lens itself increases.

5. Super maturity

Crystal protein has reduced the process of dissolving and absorption and complication of concurrent lens.

6.morgagnian stage

In a stage of the ultra -ripe period, at this stage, the entire lens cortex was reappeared, and the crystal nucleus stayed at the bottom of the crystal bodies.
