AREDS2 Age-Related Macular Degeneration Classification

Classifies AMD severity by AREDS2 categories based on drusen size and pigmentary changes: Category 1 (no AMD), Category 2 (early AMD — small drusen), Category 3 (intermediate AMD — medium/large drusen or geographic atrophy <1 disc area), Category 4 (advanced AMD — geographic atrophy or neovascular AMD).

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

Classifies AMD severity by AREDS2 categories based on drusen size and pigmentary changes: Category 1 (no AMD), Category 2 (early AMD — small drusen), Category 3 (intermediate AMD — medium/large drusen or geographic atrophy <1 disc area), Category 4 (advanced AMD — geographic atrophy or neovascular AMD)

Each component has a specific meaning:

  • Drusen size — The drusen size recorded for the scenario being assessed.
  • Pigmentary changes: Category 1 — The pigmentary changes: category 1 recorded for the scenario being assessed.
  • Category 2 — The category 2 recorded for the scenario being assessed.
  • Category 3 — The category 3 recorded for the scenario being assessed.
  • Category 4 — The category 4 recorded for the scenario being assessed.

Note: Interpret the areds2 amd classification result against the thresholds and context described above.

How to Use

Enter the drusen size, pigmentary changes: Category 1, Category 2, Category 3, Category 4 for the scenario you are assessing. Classifies AMD severity by AREDS2 categories based on drusen size and pigmentary changes: Category 1 (no AMD), Category 2 (early AMD — small drusen), Category 3 (intermediate AMD — medium/large drusen or geographic atrophy <1 disc area), Category 4 (advanced AMD — geographic atrophy or neovascular AMD). Use the areds2 amd classification result to inform your calculation.
