Pupillary Light Reflex Grading Scale Calculator

Grade pupillary light reactivity from +3 (brisk) to -1 (absent) for prognostication in coma, TBI, and herniation assessment.

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

Grade pupillary light reactivity from +3 (brisk) to -1 (absent) for prognostication in coma, TBI, and herniation assessment

Each component has a specific meaning:

  • +3 — The +3 recorded for the scenario being assessed.

Note: Interpret the pupillary reflex result against the thresholds and context described above.

How to Use

Enter the +3 for the scenario you are assessing. Grade pupillary light reactivity from +3 (brisk) to -1 (absent) for prognostication in coma, TBI, and herniation assessment. Use the pupillary reflex result to inform your calculation.
