Yeah, I've also been diagnosed with dry MD (mac.degeneration), moderate case for now. My former eye doctor first noticed it and we discussed PreserVision, an eye vitamin that is touted to slow down, not cure, MD and stave off wet MD. I brought it up because my elderly aunt takes that for her wet MD. My eye doctor said the med has proven to only help by a small percentage, he said I could take it or not - up to me.
My new eye doctor, the surgeon who's doing my surgeries, handed me a trial box at my very first visit with him. I questioned him about its usefulness, and he seemed a bit peeved. Said 30% is better than nothing. The med is expensive and OTC, pretty sure Medicare won't cover it. I'm still debating, but will probably be worried if I'm wrong in not taking it.
