I'm a semi-retired O.D. and am working on halting the progression of dry AMD.
When I graduated decades ago AMD was rare. Now it's a leading cause of blindness.
I can tell you this much. It's easier to prevent than to reverse.
Red blood cells are double the diameter of the opening of the capillary they must squeeze through. No, God didn't make a mistake. Your eyes and brain comprise only 2 to 3 % of your body weight yet consume ~35% of your body's oxygen supply. In order to deliver their 02
to the macula they must fold in half like a taco, putting the wall of the RBC in contact with the endothelium of the capillary for maximum diffusion of 02 out and C02 in to the RBC. The RBC's must be singular, not stuck together
for this process to work.
Read the chapter "Blindness and Oils" in the book Young Again by John Thomas for dietary advice.
Best health wishes.
