Does NTG really need eye drops???

Hello, I have just now found your website after searching for contact information concerning Drs Marc and Michael Rose and their book "Save Your Sight".  

Last week I was diagnosed with NTG in my left eye.  My dr has been watching the "cupping" in the 5:30 to 6:00 area of my eye for several years.  For the past few weeks I have noticed a "shadow" in my upper peripheral view.  When I went to my dr, she said she did not see any change in the cupping but since I am now seeing the shadow she is wanting me to use Xalatan drops.
