The International Classification of Diabetic Retinopathy

Proposed international clinical diabetic retinopathy and diabetic macular edema disease severity scales.

Ophthalmology 2003Sep;110(9):1677-82.


The classification of diabetic retinopathy

The Classification of Diabetic Retinopathy

  • Mild Nonproliferative Diabetic Retinopathy:

    • Microaneurysm only

  • Moderate Nonproliferative Diabetic Retinopathy

  • Severe Nonproliferative Diabetic Retinopathy: 4, 2, 1


The classification of diabetic retinopathy1

The Classification of Diabetic Retinopathy

  • Severe Nonproliferative Diabetic Retinopathy:

    • Microaneurysms and/or dot blot hemorrhages more than 20 dots in 4 quadrant

    • Venous beading in 2 quadrants

    • Intraretina Microvascular Abnormalities (IRMA) in 1 quadrant


The classification of diabetic retinopathy2

The Classification of Diabetic Retinopathy

  • Proliferative Diabetic Retinopathy:

    • New vessels at the optic disc

    • New vessels elsewhere

    • Vitreous hemorrhage

  • Macular edema

    • Exudate at macular area
