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

Interpret Humphrey visual field perimetry Mean Deviation (MD) to classify glaucoma severity and rate of progression using established Hodapp-Parrish-Anderson criteria and trend analysis

Each component has a specific meaning:

  • Established Hodapp-Parrish-Anderson criteria — The established hodapp-parrish-anderson criteria recorded for the scenario being assessed.
  • Trend analysis — The trend analysis recorded for the scenario being assessed.

Note: Interpret the perimetry md result against the thresholds and context described above.

How to Use

Enter the established Hodapp-Parrish-Anderson criteria, trend analysis for the scenario you are assessing. Interpret Humphrey visual field perimetry Mean Deviation (MD) to classify glaucoma severity and rate of progression using established Hodapp-Parrish-Anderson criteria and trend analysis. Use the perimetry md result to inform your calculation.
