Glaucoma Visual Field MD Rate of Change

Assess glaucoma progression using mean deviation (MD) rate of change on Humphrey visual field (HVF). MD worsening >-1.0 dB/year indicates rapid progression requiring treatment intensification.

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

Assess glaucoma progression using mean deviation (MD) rate of change on Humphrey visual field (HVF). MD worsening >-1.0 dB/year indicates rapid progression requiring treatment intensification

Each component has a specific meaning:

  • Mean deviation rate of change on Humphrey visual field — The mean deviation rate of change on humphrey visual field recorded for the scenario being assessed.

Note: Interpret the glaucoma vf md rate result against the thresholds and context described above.

How to Use

Enter the mean deviation rate of change on Humphrey visual field for the scenario you are assessing. Assess glaucoma progression using mean deviation (MD) rate of change on Humphrey visual field (HVF). MD worsening >-1.0 dB/year indicates rapid progression requiring treatment intensification. Use the glaucoma vf md rate result to inform your calculation.
