background diabetic retinopathy

Last edited 05/2023

This is the earliest stage of diabetic retinopathy; very common in people with diabetes.

  • The Wisconsin Epidemiologic Study of Diabetic Retinopathy reported that background diabetic retinopathy (microaneurysms and haemorrhages) was present in nearly all subjects with type 1 diabetes of 20 years' duration, and in 80% of those with type 2 diabetes of a similar duration (1).
  • Pathology is intraretinal.
  • Lesions are often situated between the main temporal arterial arcades.

Background diabetic retinopathy is graded as level R1 in the UK National Screening Committee (NSC) grading criteria (2).
