Glycaemic threshold for diabetes-specific retinopathy among individuals from Saudi Arabia, Algeria and Portugal.
We studied the glycaemic threshold and prevalence of diabetic retinopathy in screen-detected diabetes in Saudi Arabia, Algeria and Portugal. The prevalence of diabetes-specific retinopathy started to increase at an HbA1c level of 6-6.4% (42-47 mmol/mol) and in individuals with HbA(1c) >7.0% the prevalence was 6.0%.
