Table. Dynamics of pupillometry indicator values after the micropolarization procedure
Note: Di (mm) — initial pupil diameter before the light stimulus; Df (mm) — final pupil diameter; Tl (s) — time of the latent period of pupillary reaction; Tc (s) — pupil constriction time (parasympathetic phase); Td (s) — pupil dilation time (sympathetic phase); Vc (mm/s) - average pupil constriction speed; Vd (mm/s) — average pupil dilation speed; Ac (mm) — amplitude of pupil constriction. Pupil reaction is a reliable indicator of the level of attention; * — value is significant with respect to background (р ˂ 0.05; Wilcoxon test).
