From: Melanopsin-mediated pupil function is impaired in Parkinson’s disease
Normalised pupillary unrest in darkness (mean ± 95% confidence intervals). Data from PD group (light tracings, n = 17) and control group (dark tracings, n = 12) are shown in panels A and B respectively. To control for individual differences in baseline pupil diameter, the data are normalised to the first 10 s of recording.
