​Funduscopy. The association of typical microvascular problems found in people with diabetes mellitus is thought to be due to parallels in vascularization between the retina and the kidneys. Patients with type 2 diabetes with proliferative retinopathy frequently have kidney involvement, which is characterized as either microalbuminuria (in the early stages) or overt proteinuria (in the later stages). As a result, all individuals with diabetes and proliferative retinopathy should have their kidney function evaluated, including microalbuminuria tests. Although the presence of retinal suggests a diabetic source of proteinuria, the absence of diabetic retinopathy does not rule out the possibility of diabetic nephropathy.
