Dr. S. I need your help with an eye disease!!!

Hello all,
I would like to help an old friend of mine that I recently ran into after about 9 yr. absence. She told me she was diagnosed 2 1/2 years ago with Retinitis Pigmatosis ( pigmentosis...not sure which or how to spell...sorry!!) They told her she will eventually go blind and there is nothing that can be done for it. She can no longer drive....it is getting worse rapidly.
I was wondering how the Eyebright, Brain Formula and the Superfood would do for her?
Any advice or help you can offer would be greatly appreciated!!!
Thank you so much.
God bless,
Sher
