I discovered these when I was lying in bed last week reading my texts with my left eye shut (I was lying with my head on my arm) forgot about it for a few days then covered my left eye and could see the white-ish grey shapes floating down in front of whatever I looked at. I am trying to not worry about it but it's hard not to because I know I've not done enough to get my sugar level under control in ten years. my mother has diabetic retinopathy which has gotten progressively worse in the past 18 months- two years. I have made an apt with my optician who's the only one in town that has the equipment to take a photo of the back of the eye.
