Scientists identify natural chemical that causes blinding blood vessel growth
...ciency. VEGF turns on its receptor, a switch that ignites
a chain reaction culminating in new blood vessel growth. However, these backup blood vessels are faulty; they leak, bleed and encourage scar tissue that detaches the retina, resulting in severe loss of vision. Such growth is the hallmark of diabeti...
