Diabetic Retinopathy

Diabetic retinopathy is a condition that is related to the diabetic people which affect the eyes. It actually causes the damage to the blood vessels of the light-sensitive tissues at the back of the eye. At the beginning, diabetic retinopathy may cause no symptoms or only causes a mild vision problem. But eventually, it can cause blindness to the person affected.

However, the eyes to try to grow new blood vessels but it does not develop very well. So eventually they start to weaken and leak blood and fluid into the retina. This causes a particular condition which is called edema, that makes your vision blurry.

This extra pressure can cause the retina to detach. Generally, it leads to a condition called glaucoma and it eventually causes the blindness to the person.
