Oh I am so sorry, I think I know how you are feeling, I have been low carbing with Hb1AC never higher than 5.2, avoiding post prandial spikes, eating plenty of fresh veggies and berries, drinking tea,all supposed to be full of antioxidants that are so beneficial for our bodies. including they eyes.....and then, a few months ago it was, I woke up and saw black blotches in front of me!!
I had a bleed in my left eye, was treated with laser, luckily my retina was fine, I just had a follow up check up last Thursday, all looks ok.
It was such a shock to me, thought with my careful control of bg levels, surely nothing can happen to me, even my consultant was visibly upset, but sadly we dont get a guarantee.
Yes careful control of bg levels is still very, very important, whether you achieve it by low carbing or other means, its important to keep good levels, or things could even get worse than an occasional bleed in the eye, that can be fairly easily dealt with (<<<words of wisdom from my consultant after I asked 'is it b%^$^y worth it').
