Age-related Macular Degeneration (or AMD), is the number one cause of visual loss among the elderly in the developed world. It involves the macula, an area with a diameter of a few millimeters, located in the center of the retina. This part of the retina is unique in several ways: it has no blood vessels of its own but is supplied by choroidal vessels situated underneath the retinal pigment epithelium.
