Diabetes affects many parts of the body including eyes. Diabetes causes the fine tubes that carry blood to the retina to become damaged, which causes the image of objects on the retina to be formed correctly or not at all. This problem is called diabetic retinopathy. If it is not treated properly, the patient may become a victim of blindness. People between 20 and 70 years old are more prone to this. Initially, this disease is not detected. When the eyes get affected up to 40% of the disease, then its effect starts showing.
The insulin of the body is affected due to diabetes. This insulin delivers glucose to the body. When insulin is not produced or becomes low, glucose cannot enter the cells and dissolve in the blood. For this reason, the level of sugar in the blood increases. This blood reaches all parts of the body. The longer the diabetes lasts, the greater the likelihood of diabetic retinopathy. Blindness can be reduced by up to 60 percent after treatment with laser technology. When the blood flows continuously with high sugar, it can damage the blood vessels. The blood vessels of the eyes are the most delicate in the body, so they are first affected. Blood from the blood vessels ruptures often accumulates around the retina, which can also cause blind spots in the eyes.
