Dog Cataracts:Causes, Treatment, and Related Symptoms

Dog Medicine
Overview
Cataract is a change in the lens in the eye. Normal crystals are transparent and crystalline, and their primary function is to help focus light and images. When a cataract is formed, the lens becomes cloudy or blue or white. Typically, cataracts are classified as mature or immature. Immature cataracts mean that only part of the lens is affected, so vision is barely affected. If the cataract develops to a mature stage, the entire lens will be affected and vision will disappear.

Causes of Dog Cataracts

Cataracts occur due to denaturation of tightly bound proteins on the lens.
 

Dog Cataracts Symptoms

The center of your dog's pupil (the lens) becomes cloudy. Cataracts are also often associated with retinopathy, so dogs often experience symptoms similar to night blindness. When the ambient light becomes dim, the dog may experience symptoms of blindness and cannot distinguish the relative position of objects around it.
 

Diagnostic criteria for Cataract in Dogs

Diagnosis by imaging: Ultrasound examination of the eye: the size of the lens can be diagnosed, if the lens becomes small, it is oversold, indicating that the condition may have been present for some time.
Blood examination: general attention should be paid to the blood glucose value and blood calcium value, if there is a phenomenon of diabetes or low blood calcium, indicating that the lesion of the lens may be caused by this.
 

Cataract Treatment

Early cataract can be improved by continuous use of mydriasis or use of other drugs to alleviate the process of the disease, such as the use of thalidomide, catarrine and other eye drops to prevent the formation and accumulation of insoluble proteins, generally for senile cataract, diabetic cataract is more effective. However, these drugs can only delay the time of lens opacification, and their efficacy is not obvious, and they are usually used only for prevention. It can also be treated surgically: intracapsular cataract resection, extracapsular cataract resection, phacoemulsification.
