Early Symptoms of Cataracts in Dogs

1. There are no obvious symptoms in the early stage of cataract. Owners generally don't notice that their dogs have poor eyesight. But as the disease progresses, the dog's eyes begin to become blurred. Sometimes the dog's eyeballs are obviously not bright, they will become cloudy, and sometimes there are obvious white spots.

2. The initial symptoms are turbidity in the crystal and capsule, which develops slowly, does not affect the dog's vision, and has light reflection. As the disease progresses, the cloudy area of ​​the lens expands to the point of full cloudiness, ranging from sensitivity to light reflex to blurring, and the dog's vision begins to deteriorate until blindness.

3. Canine secondary cataract: secondary to other eye diseases and systemic diseases, such as iritis, uveitis, diabetes, etc.
