How Does It Work?

Wet macular degeneration is caused by abnormal blood vessel growth in the back of the eye. The blood vessels grow behind the retina, underneath the macula (a part of the retina that is essential for detailed vision). These new blood vessels are not normal and are weak and prone to leaking. Leaking causes damage to the macula, which causes "wet" macular degeneration.
 
Macular edema following retinal vein occlusion is caused by a blockage of a retinal vein, leading to the leakage of fluid.
 
Ranibizumab is part of an antibody that is designed to bind to and inhibit vascular endothelial growth factor (VEGF-A). VEGF-A is a naturally occurring protein that encourages blood vessel leakage and the growth of new blood vessels (including abnormal blood vessels). By binding to VEGF-A, ranibizumab prevents this protein from encouraging new blood vessel growth and blood vessel leakage. This helps to slow down (or even reverse) vision loss and macular damage.
