  1. NPi  Neurological pupil index, Size  Maximum diameter: maximum pupil size before constriction, MIN  Cinimum diameter: pupil diameter at peak constriction, CH  Change: (Size - MIN)/Size as a percentage, MCV  Maximum constriction velocity: maximum velocity of pupil constriction of the pupil diameter responding to a flash of light, measured in millimeters per second, LAT  Latency of constriction: time of onset of constriction following initiation of light stimulus
