Brain not "showing me" my peripheral vision

I think I forgot to tag you in my last response, sorry. (You may want to read it first) I wanted to mention an idea that my neuro-Opthalmologist had that we are trying at the moment, as it seems like an interesting idea. So far I've not seen any effect though or improvement.
We switched to prism glasses, with the prisms focus all the way around my peripheral.
As you probably know, prism lenses are usually used for people that have a spot missing out of their vision from brain damage or a stroke, and the extra light directed in from the prisms at that spot forces the brain to pay attention to the missing spot, and from what I've read it seems that it usually works very well in making the brain start acknowledging the missing spot again.
I've had the glasses for 2 days now, and so far have not seen any improvement.
We did do a test with the glasses, measuring my balance on a very sensitive board that somewhat resembled a scale. Although I could not tell any difference in my balance with the prism glasses compared to without, the board measured even the slightest movement in my feet and determined that my balance is actually better with the prisms than it is without them.
Since the brain uses vision and the view of things around you to balance your body better, he determined that from the test the prism lenses were in fact giving my brain more information than my normal glasses. Basically the prism lenses were letting my brain get more information from my peripheral, and put that to work to improve balance.
The remaining question was whether my brain would use this additional information to give me my peripheral back or not, which so far has not, but still is a pretty interesting theory and test .
Anyway, just wanted to add that, since it seems to be an interesting test and experiment.

How long have you been using the prism lenses? Brain plasticity is not instantaneous, may take a while to produce a noticeable difference.
I hope you find an answer. I know for me, I have significantly less peripheral vision in low light, but assume it has to do with cataract formation, age and mild glaucoma.
Can you get a neuro ophthalmologist to present you as a case study?
