Scientists supported by Diabetes UK have found a molecule that could be used as a new treatment for retinopathy in the future. The molecule acts by reducing the leakage of small blood vessels at the back of the eye. The researchers tested the effects of a molecule called VEGF-A165b on cells grown in the lab and blood vessels in the eye of a laboratory model of diabetes. The molecule was able to reduce the leakage of blood vessels and stop them growing uncontrollably. Since VEGF-A165b is naturally found in our bodies, scientists hope they can find a way to increase its production in humans, to protect people with diabetes from developing eye damage.
