Pupillary light reflex (PLR) testing looks at these key metrics after a concussion: 👉Max/Min Diameter: Maximum and minimum size of the pupil during the reflex. 👉% Constriction: How much the pupil constricts when exposed to light. 👉Latency: The time it takes for the pupil to start reacting. 👉Average Constriction Velocity: How quickly the pupil constricts. 👉Peak Constriction Velocity: The fastest speed during constriction. 👉Average Dilation Velocity: Speed of the pupil returning to baseline.
