Family: Eye and ear diseases
Symptoms: turbid cornea and blindness
Cataract is the change of the lens in the eye. Normal crystals are transparent crystals, and their main function is to help focus light and images. When a cataract is formed, the lens becomes cloudy or blue or whitish. Under normal circumstances, cataracts are divided into two types, mature or immature. Immature cataract means that only part of the lens is affected, so vision is almost unaffected. If the cataract develops to the mature stage, the entire lens will be affected and vision will disappear.
Cataracts occur because of the denaturation of tightly bound proteins on the lens.
The main symptoms
The center of the dog's pupil (the lens) becomes more cloudy. Cataracts are also often associated with retinopathy, so cataracts in dogs symptoms similar to night blindness. When the ambient light becomes dim, the dog will have symptoms of suspected blindness and cannot distinguish the relative position of surrounding objects.
Diagnosis by imaging: ophthalmic ultrasound examination: the size of the lens can be diagnosed. If the lens becomes very small, it means that it is over-mature, indicating that the condition may have appeared for a while.
Blood test: Generally, you should pay attention to the blood glucose and calcium levels. If diabetes or hypocalcemia occurs, it means that the lens disease may be caused by this.
Early cataracts can still be improved by continuous use of Adriatic to improve vision or use other drugs to alleviate the onset process, such as the use of cataracts, Catalina and other eye drops to prevent the formation and accumulation of insoluble protein in the lens, generally for senile cataracts, diabetes Sexual cataract is more effective. However, these drugs can only delay the time of lens opacity, and the effect is not obvious, and they are usually only used for preventive purposes. It can also be treated by surgery: cataract intracellular resection, extra capsular cataract resection.
