Hi outdoorgirl,
On this subject I could talk all day about, as I have had problems in the past with diabetic retinopathy, but thankfully it has been settled for some time now.
All I will say to you is make sure you keep tight control of your diabetes, keep your blood pressure below normal, likewise with your cholesterol, and make sure that you eat a well balanced nutritional diet with ample amounts of fruit and vegetables. Background Retinopathy can in some case remain just that, provided you take precautions now to stop this condition developing. Keep all appointments with gp and your eye clinic, and should you have any concerns ask your consultant at your next eye screening appointment.
Best wishes
Nigel
