Diabetic retinopathy and insulin therapy in a rural diabetic population

The prevalence of diabetic retinopathy was lower in a rural diabetic population when compared to the prevalence of diabetic retinopathy in medical center clinic populations. Adult-onset (Type II) diabetics were at greater risk for developing diabetic retinopathy shortly after diagnosis than newly diagnosed cases of juvenile diabetes (Type I). The use of insulin positively correlated with the prevalence of diabetic retinopathy in this rural population.
