highly significantp<0.001
Ocular parameter analysis Pupil dynamics analysis We observed that low frequency PD variations show highly significant (p<0.001) strong positive correlation (r(58) = 0.668 for left pupil and r(58) = 0.64 for right pupil) with respect to PIW. rmcorr also confirms a positive relationship (r rm (47) = 0.66, p<0.001 for left pupil & r rm (47) = 0.63, p<0.001).
