Example of pupillary diameter [PD] assessment in the closed eye by B-mode ultrasound.
(A) PD at rest under standard dimmed light conditions of the ultrasound study room. (B) PD during ipsilateral light stimulus [Lstim]. (C) PD during contralateral Lstim. Crosses represent the markers set by the examiner for measuring the PD.

Correlations of pupillary diameter (PD) with age.
Y-axis: all PD’s in millimeters, x-axis: age in years. Lstim = light stimulus, r = Pearson correlation coefficient, p < 0.001.
Fig 4.
PD at rest—exemplarily for the right eye.
X-axis: average of means for measurement 1 and 2 for every patient, PD in mm. Y-Axis: Differences between both measurements in mm. Upper and lower 95% limits of agreement are indicated.
