I got my first, perceptible bit of retinopathy two years ago, about 12 years after my pre-diabetes diagnosis. And that was with some spotty glucose control along the way. My A1c's have bounced around between 5.5 and 8.5 over the years. Yeah.... I know.
I feel for anyone receiving the news of retinopathy, even mild retinopathy. It's a difficult thing to find out that you're anywhere on a continuum that eventually leads to blindness, even if you're just dipping your toes into the water.
At fifty, I've had to learn that this is the case on many fronts. I'm going a little bit blind, a little bit impotent, a little demented, a little bit arthritic... Given that being alive is basically to exist on an "ashes to dust" continuum that culminates in eventually being dead, it makes sense. Other than youth, the elderly are the happiest among us. That, presumably because they have achieved acceptance of that which is inexorable.
My retinopathy is in one eye only which drive me nuts. I abhor asymmetry in myself and would rather have it in both eyes.
As for care, I don't know that there's much to be done other than to use it as motivation for better glucose control moving forward. Retinal surgery is an intermediate option but both of us are surely a good long ways from that.
