The correlation between age and early poststimulus pupil response (AUC) at 300 cd/m 2 blue light conditions. The linear correlation of age to the summed poststimulus pupil response within the first 10 seconds after light termination (early AUC 0–10) was highly significant (Pearson correlation coefficient r = 0.43), with increasing age corresponding to a larger pupil contraction (solid line is regression line, the dashed lines represent the 95% CI).
