The theory of 'metabolic memory' says that current retinopathy status is based on past, not current, HbA1c values.
HbA1c 2 to 3 years earlier had the greatest relative risk contribution to current progression of retinopathy. HbA1c up to 5 years earlier made a greater contribution than current values, while values from 8 years earlier still had an important impact. When HbA1c had been at 8% for a long period and was subsequently lowered to 7%, the salutary effects did not begin to appear until 2 to 3 years after lowering.Background retinopathy does not affect your eyesight. Just a single microaneurysm will result in a 'background retinopathy' letter and tends to last a few years before it disappears. Thus, even if no new retinopathy occurs, the person continues to get a 'background retinopathy' result. Retinopathy is likely to improve with continued good glycaemic control.

My first retinal scan result was ''Background Retinopathy'' my second result was clear but my vision is getting more blurred which I don't understand.
I'm not sure if I read somewhere recently that it is a good idea for D's to wear sunglasses when the sun is bright... or is that for the population in general.
Any thoughts?
Cheers
Sunlight can increase the risk of cataracts - people with diabetes are already at greater risk. It also increases the risk of age-related macular degeneration, pterygium, pinguecula, cancer of the conjunctiva and eyelid cancer.I'm not sure if I read somewhere recently that it is a good idea for D's to wear sunglasses when the sun is bright... or is that for the population in general.

Hankjam - I think we should all be using shades in bright sunshine, but particularly those with paler eyes.
I know whan I have spent a lot of time overseas in the sun, if I don't use shade for any length of time, my eyes can become tired and dry.
@Rachox I am so thankful you posted this thread. I got my retinopathy results today which show some background retinopathy. I would have been quite worried about it had it not been for these wonderful answers.
In six months I got my HbA1c from 122 to 35. So a drop fairly quickly. I intend to keep on top of things and I am content to wait and see what the next results are next year.
So thanks to everyone for your helpful replies, you have saved me from becoming a gibbering idiot!
Hi there. I posted a similar concern a month or so ago in reply to a thread about reversing diabetes. My eye test has gone from good to background retinopathy over a 12 month period where my HBa1c was constant at 38! Sorry I can't remember the specifics, but a search should find it, someone pointed me to a link about spiking of BG. I had stopped my regular testing around meals thinking it was not necessary with such good HBa1c, but I started again and found I was regularly spiking after meals. As I recall it, the research papers suggest that short term spiking is more relevant to diabetes complications than average levels I.e. HBa1c results. I'm due another test next month, and have adjusted my diet to stop the spiking ( I think anything over 7.9 2 hours post prandial on a regular basis is likely to lead to retinopathy) Sorry I can't point you to the links, I'm typing from a mobile and struggling to find my post that brought this subject up. Hope you can find it, or someone else can point you in the right direction. Needless to say I was cross with myself for just assuming I was in control based on HBa1c results alone. Diabetes is a complex disease and will trick you at every opportunity if you allow it, so stay one step ahead if you can, and congratulations on your results so far.I was diagnosed Type 2 on 9th May last year with an HbA1c of 70. I had my first retinal screening ten days later and results were clear. My next Hba1c two months later was 45, then in the Sept was 36, and has been in the 30s ever since. I just received this year’s results and I have “some background retinopathy”
Why?I have been so strict with myself, controlling my blood sugars, my blood pressure is down and I’ve lost shed loads of weight. It’s not fair

To @Rachox @Resurgam @Jaylee @sally and james @Scott-C @Guzzler @Bluetit1802 @DCUKMod @drahawkins_1973 @bulkbiker @hankjam @EllieM @therower @xfieldok @Dark Horse @Energize @Pipp @mr_cat @Ian_Laye @TonyHancock @Jo123 @Mick1952 Here is an excerpt from a letter I wrote to my screening service, adapted for obvious reasons!Thanks for your reply. Even a year from diagnosis I test at least 4 times a day, before and 2 hours after breakfast and dinner, my post prandial readings have rarely exceeded 7 since six weeks after diagnosis. I think in my case the explaination is probably historical as suggested by the research posted by @Dark Horse in post #21
