Diabetic Retinopathy - Cause
Diabetes damages small blood vessels throughout the body, leading to reduced blood flow. When these changes affect the tiny blood vessels in the eyes, diabetic retinopathy may occur.
In the early stage of diabetic retinopathy, tiny blood vessels in the eye weaken and develop small bulges that may burst and leak into the retina. Later, new fragile blood vessels grow on the surface of the retina. These blood vessels may break and bleed into the eye, clouding vision and causing scar tissue to form.
Weight Loss Surgery and Type 2 Diabetes
Obesity, in itself, is a major medical risk. But obesity with type 2 diabetes significantly raises the risk of heart attack, stroke, and other major medical problems associated with diabetes. Increasingly, weight loss surgery is being used as a tool to manage type 2 diabetes. That's because controlling diabetes and managing the related health risks is directly related to losing weight.

The scar tissue may pull on the retina, leading to retinal detachment. Retinal detachment occurs when the retina separates from the wall of the eye. This can lead to vision loss.
