I started my pump back in June as well, and I also have changes in my eyes that might require lazering...
I was warned that this might happen with the improved when I started my pump therapy...
I know that this seems to have come on quick for you and is a worry... But keep in mind even though these changes have happened pretty quick that it is less likely that it has done enough damage that can't be sorted by lazering... As it has Less chance of scaring the important bits, if the photo's were showing that there was a high degree of pending damage they would have had you straight into clinic to reslove it..
My husband has had both major eye surgery and lazer treatment due to his diabetes 9 years ago starting from a bleed in one eye that did detach his retnia, the operation to clear the blood and and reattach the rentia was a success, with limited damage of his sight over the next 4 years he had a couple of lazering completed on his check-up appointments and a final op to stablize his eye (and gained improvments as a added bonus) which so far in the last 5 years he hasn't had any more problems or lazering but still has 6 monthly checks with the specialist... which normanly means that he gets a audience as it's rare that they see this sort of damage in a diabetic!
You need to see this as a glitch in your diabetes, it doesn't mean that you are going to go blind or heading towards blindness as even though with the better control that you are achieving has in a way accelerated your eye condition, they can do something about it and once you your body settle to the better control then any problems with the eyes will lessen once they've sorted everything...
