Figure 3. A-E: Diagrammatic representation of parameters paired with eye photographs of a stimulated blink. A-D: Sequential stages of the stimulated blink reflex with paired eyelid location over time charting. E: Complete charting of a stimulated blink reflex with parameters labeled. The “threshold” line is considered the horizontal mid-pupil position. Time under threshold (not shown) measures the total time the eyelid remains below the mid-pupillary line (i.e. threshold).
