I agree with Charon...
I too strongly suggest that if this has 'just happened', then really you need to go to an emergency eye clinic to get it looked at straight away.
It's unlikely they can do anything immediately, but the consultant will be able to see what has happened and explain it to you so that you can be aware of what action is needed, etc.
Without knowing more detail, and from personal experience, it sounds as though you've had a large bleed in the eye that is still fuzzy; this may clear on its own or you may need a vitrectomy if the blood doesn't clear sufficiently to laser. I can't speak for the eye where you've completely lost vision, but I hope it's ok.
That aside, there is a great deal of research going into the use of stem cells and other things that help the eye heal itself and resolve the symptoms of retinopathy - personally, I'm hoping for a solution sooner rather than later.
However, the primary thing to do is regain control of your Blood glucose levels and eat a healthy diet and these will help the body to heal itself (to some degree).
Good luck... please let us know what happened as we're all in the same boat and will be here for you.
Best wishes,
Conrad
