Many diabetics could be saved from blindness after scientists found a way of preventing a sight-threatening disease that affects them.
One of the common complications of diabetes is diabetic retinopathy, which can cause blindness if left untreated.
Diabetic retinopathy occurs when high blood sugar levels damages the area at the back of the eye known as the retina.
Many diabetics could be saved from blindness, as scientists may have found a way of stopping diabetic retinopathy, a common complication of the disease.
A delicate network of blood vessels supplies the retina with blood. But when these become blocked, leaky or grow haphazardly, the light-sensitive retina becomes damaged and is unable to work properly.
The new research found blocking two proteins which trigger the growth of blood vessels could prevent the disease.
