I don't have retinopathy and I'm not a T1 so I can't answer your question, but if I may, I have a couple of comments/questions...
It does seem unusual to have diabetic retinopathy if your HbA1c is 6.5% (48 mmol/mol) because that is the threshold at which the HbA1c becomes diabetic. I see you are 22 and have only been diagnosed as T1 for a short time. I have always thought that higher HbA1cs over a long period increases the risk of complications. What are your BGs like day to day?
It might be worth getting a second opinion on the diagnosis of retinopathy. What did the optometrist/opthalmologist/doctor say about it? Did they say it was retinopathy or the early stages of it, or early signs of it? Have you had a diabetic eye test before this? I wonder if retinopathy can be caused by something other than diabetes?
