There are two types of late AMD--geographic atrophy, and the more common neovascular AMD, also known as wet AMD. In neovascular AMD, fragile blood vessels grow under the retina and leak fluid. This usually starts in one eye, and is stimulated by a protein called VEGF. Just 10 years ago, people diagnosed with neovascular AMD were almost certain to develop severe vision loss in their affected eye and likely to lose vision in their other eye, too.
