Hi, sorry to read about your difficulties. I have no personal experience of this myself.
Bilous and Donnelly, which is the NHS Handbook on Diabetes, says that retinopathy is the general term as the retina is the main part of the eye affected, but both the iris and the lens can also be involved. Maculopathy is defined as insufficient blood flow (ischaemia) to the central retina (the macula) which can result in swelling and damage. So maculopathy is a subset of retinopathy.
One of the key points says:
Prevention of retinopathy development is critical; glycaemic control, blood pressure lowering and renin angiotensin system blockade are of proven benefit.
I would strongly suggest that you take the advice of your medical team. I have no idea what renin angiotensin system blockade is, but clearly there is an expected benefit to reducing both your blood glucose and blood pressure, which is something you yourself can do something about.
