My advice is to go to a retinologist also who will do an even more thorough exam and give you a better assessment about what to do about the macular thing. Research doctors online and go to the best one in your area at a good research hospital. And make sure you go once per year or however often they tell you to, to the doctor who will treat you from now on for the exam where your eyes are dilated and everything is looked at. A retinologist uses a very bright light to look at everything.
I read somewhere that tight control after a higher a1c can cause retinopathy, I'm not sure why or if that is the case for everyone. My blurry vision hasn't resolved completely since dka although it has improved greatly, but nothing can be found except for a shadow of cataract which they said is so minor it's not worth mentioning.
My most recent doc said to have this exam every year.
Another thing she said was not to stop reading etc. I read a lot online and was worried this is straining my eyes... she said it's like the brain.. we have to keep using it.
As for what to do, I think you need to figure out what is causing the blood spots first. Did your doc say anything about that?
I was using an eye drop for dry eye for a few years before D for severe dry eye and I sleep with a moisture goggle at night, using the drops beforehand. I now added in a drop with acetyl carnocine and cinammon supplements- I read that they can help prevent cataracts. Some people say these drops have reversed cataracts in their dogs, dogs with D progress very rapidly to cataracts. I also wear sunglasses, motorcycle glasses, most of the time outside.
Here is a link I'm glad I found, think it will help.
