I had background retinopathy for quite a few years inone eye.
I got a cgm for 6 months prior to my next eye check. The cgm did allow me to lower my standard deviation of my levels. My retinopathy I believe disappeared because of liwering my sd. I have no proof of this, but cannot see (ha, ha!!) any other reason for it to disappear.
My Freestyle Navigator CGM imploded.. So iscompletely useless... Although I still try to keep my sd under 3.0 it is made more difficult to do with just blood testing.
It will be intersting to see what happens to my eyes at my next check up- with no CGM.
