Proliferative DR High-Risk Characteristics

Identify high-risk proliferative diabetic retinopathy (PDR) characteristics from DRS and ETDRS: NVD >=1/4 disc area OR any NVD with vitreous hemorrhage OR NVE >=1/2 disc area with vitreous hemorrhage.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Identify high-risk proliferative diabetic retinopathy (PDR) characteristics from DRS and ETDRS: NVD >=1/4 disc area OR any NVD with vitreous hemorrhage OR NVE >=1/2 disc area with vitreous hemorrhage

Each component has a specific meaning:

  • DRS — The drs recorded for the scenario being assessed.
  • ETDRS: NVD >=1/4 disc area OR any NVD — The etdrs: nvd >=1/4 disc area or any nvd recorded for the scenario being assessed.

Note: Interpret the pdr high-risk features result against the thresholds and context described above.

How to Use

Enter the DRS, ETDRS: NVD >=1/4 disc area OR any NVD for the scenario you are assessing. Identify high-risk proliferative diabetic retinopathy (PDR) characteristics from DRS and ETDRS: NVD >=1/4 disc area OR any NVD with vitreous hemorrhage OR NVE >=1/2 disc area with vitreous hemorrhage. Use the pdr high-risk features result to inform your calculation.
