Golden Rather Dog (details)

Dog cataract refers to changes in the crystals in the eyes of dogs, while cataract can be divided into two categories: maturity and immature. Untitled cataracts are only damaged by some crystals, generally do not affect vision, and mature cataracts, the entire crystal will be affected, and vision will disappear. There are mainly the following methods in diagnosis.

Diagnosis of Cataract

1. Clinical symptoms

At present, the main basis for diagnosis of dog white internal barriers in China is the clinical symptoms of the disease. When the dogs have symptoms of vision recession, such as faltering, walking in strange environments often collide to objects, unsatisfactory balls, strabismus appears, appear squinting , Easy to be frightened, extremely sensitive to the surrounding sounds, have a tendency to attack strangers, and if you look down on danger, you can suspect that there is cataract.

2. Laboratory inspection

After 10 G/L Topimramine, the assistant brings the dog into the dark chamber and for Baoding, and then the veterinarian cracks or glasses are checked. If the laboratory does not check the equipment such as glasses, you can also use a small flashlight and a magnifying glass to form a simple device to check [5].

After thoroughly checking the method, the peripheral or posterior part of the lens is a little shadow, which can be doubted.

The crack lamp is checked by microscope, and the peripheral or posterior part of the crystal body is a bit turbid, and the leather is still transparent; or after the crystal shape changes, it can be judged as cataract.

Three, ultrasound inspection

Using ophthalmology ultrasound can clearly distinguish various structures in the eyes, and the image is clear and effective. Generally, a small ultrasonic probe of 7.5 MHz is required to check the cataract. For large dogs, a 5 MHz probe is required for large dogs. If you need to get a clearer image, you need to use a higher frequency probe. When the dog's eye pain or the animal is extremely incompatible, sedative or local anesthesia is needed, and even systemic anesthesia. The normal canine crystal is obviously echoed on the B -ultrasound. When there are obvious weak echoes or strong echo around the periphery of the crystal shape, it can be judged that the dog suffers from cataract.
