Yes I agree with Sid.
It does make me angry the way they bandy about 'background retinopathy' in letters and info without thinking of the effect it has on people. Like most of us, I have a terror of anything going wrong with my eyes, and was devastated when my doc found microaneurysms - like your daughter I felt I'd been trying my best to do everything right. Thank goodness, my doc was excellent, and instead of telling me in a letter he delivered the news in person, and was able to reassure me of the following things, which I pass on to you:
a) non-urgent 'changes' in the eye usually does mean microaneurysms, (tiny, tiny bleeds) which formally counts as 'retinopathy' but really isn't a scary thing at all; even non-diabetics get them
b) they quite often go away by themselves, as Sid says. Mine did.
c) because we get free eye screening every year, we have the best possible chance of catching any problems early enough to prevent serious damage
d) even if her eyes do get worse in the future - and I bet they don't - the eye treatments that have been developed nowadays are stunningly good. We aren't talking about the bad old days any more; we're talking about people being returned to excellent sight.
I'm not saying be complacent, of course we all need eye checks every year. I'm just saying, please don't let the crude, insensitive NHS information system scare you.
