Dear Pat Davies,
I just sent you the Aspartame Resource Guide. Note that there is a URL for aspartame and blindness. It will give you a lot of information, and in Dr. Roberts medical text, Aspartame Disease: An Ignored Epidemic, www.sunsentpress.com there is an entire chapter on aspartame and the eyes.
Yes, aspartame triggers retinal detachment and bleeding. In fact, when Dr. Ralph Walton did a study on aspartame some years ago the institution stopped it. The administrator who took part in the study had a retinal detachment and lost vision in one eye. Someone else had conjunctival bleeding. Some said they were being poisoned. So the study was stopped.
I’m so sorry you weren’t warned in time. You should complain to Food Standards there but they won’t do anything, but send them a harsh letter just the same.
