Anti VEGF Injection |
Anti-VEGF drugs work by targeting VEGF (Vascular endothelial growth factor), a protein that helps the formation of new blood vessels. In the case of AMD these new blood vessels are unstable and tend to leak fluid and blood under the retina. The resulting scarring then causes irreversible sight loss. The anti-VEGF drugs inhibit the growth of new blood vessels, thereby minimising the risk of scarring.
AvastinTM targets a specific type of protein thought to cause abnormal blood vessels growth. By attacking the stimulus it can stop the blood vessels leaking and growing. In some cases it actually causes the blood vessels to regress.
