That is not an issue here. You assumed wrongly that it was and went so far as to say the patient is confused about their condition, which is absolutely false.
I have first hand information about this person, what do you have? Care to share?
They are taking supplements similar to what is being used
AREDS2 study (but more comprehensive IMO), and so far they have been able to put the brakes on the progression of their vision loss, something that was not happening previously. They were going blind, and were told as much in so many words (I have sat in on several of the appointments myself, and will do in the future).
It has nothing to do with opinion, it has to do with first hand experience, real world.
Like I mentioned, IMO she is taking a more comprehensive approach than what I know of this study. She takes the following and other stuff I can't remember off hand (I had to look some of these up for correct spellings). She also eats foods that are known to contain the beneficial antioxidants and fatty acids.
Beta carotene
N-acetyl-cysteine
Glycine
lipoic acid
Bilberry
Ginkgo biloba
Lutein
Lycopene
There are products that are specifically formulated to contain the above and more, I suggested she try those but don't know at this moment if she went that route, it just seemed easier to me than taking separate products that contain the desirable ingredients (and usually have other stuff you might not need or want).
Now please share your first hand information that will help people with macular degeneration, it's an awful thing to have anything that can slow the progression is valuable.
