Macular degeneration treatment. Close-up of the eyes of 75-year-old female patient receiving an intra-ocular bevacizumab (Avastin) injection to treat macular degeneration and retinal vein thrombosis. Bevacizumab is an angiogenesis inhibitor, a drug that slows the growth of new blood vessels. It is usually used in chemotherapy to treat a number of cancers but here is being used to treat age-related eye conditions. Macular degeneration caused damage to the macula, the central area of the retina in the eye, which leads to a loss of vision in the central field of vision. Retinal vein thrombosis, or central retinal vein occlusion, is a blockage of the central retinal vein. As one of only two sources of blood supply to the eye, occlusion of the central retinal vein can lead to blindness.
