She apparently meant that my central vision begins deteriorating. This must mean that the treatments eventually will fail to stop the progression. She gave me no prediction of when, so I just continue with what I'm doing. I did ask her if my other eye (which has drusen) will also turn "wet," and she replied, "It's a progressive disease, Mary." I guess that's a "yes," but of course she can't give me a time-line for either eye, and I don't expect her to. Meanwhile, I continue trying to take care of my eyes and my health the best I can: eating right, exercising, not smoking, keeping my weight down, etc.
