Dataset of red light induced pupil constriction superimposed on post-illumination pupil response

ABSTRACT

We collected and analyzed pupil diameter data from of 7 visually normal participants to compare the maximum pupil constriction (MPC) induced by “Red Only” vs. “Blue+Red” visual stimulation conditions.

The “Red Only” condition consisted of red light (640±10 nm) stimuli of variable intensity and duration presented to dark-adapted eyes with pupils at resting state. This condition stimulates the cone-driven activity of the intrinsically photosensitive retinal ganglion cells (ipRGC). The “Blue+Red” condition consisted of the same red light stimulus presented during ongoing blue (470±17 nm) light-induced post-illumination pupil response (PIPR), representing the cone-driven ipRGC activity superimposed on the melanopsin-driven intrinsic activity of the ipRGCs (“The Absence of Attenuating Effect of Red light Exposure on Pre-existing Melanopsin-Driven Post-illumination Pupil Response” Lei et al. (2016) [1]).

MPC induced by the “Red Only” condition was compared with the MPC induced by the “Blue+Red” condition by multiple paired sample t-tests with Bonferroni correction.

Comparisons of maximum pupil constriction (MPC) induced by “Red Only” stimuli vs. red stimuli presented during ongoing blue-light-induced PIPR (Blue+Red). Smaller values represent greater pupil constriction. Error bars represent ±1 standard deviation. Compared to the “red only” reference condition, red light exposure presented after the melanopsin-activating blue light stimulation induced greater MPC; all pair-wise comparisons reached statistical significance (df=6, *p<0.05, **p<0.01, ***p<0.001, paired sample t-test Bonferroni corrected for multiple comparisons).

Mentions: Maximum pupil constrictions (MPCs) in response to 9 intensity/duration steps of “Red Only” light stimulation (1, 3.16, 10, 31.6, 100, 316, 1000 cd/m2 for 1 s, 1000 cd/m2 for 5 s, and 1000 cd/m2 for 10 s) are compared with MPCs induced by “Blue+Red” stimuli, where the same series of red light stimulations were presented at 9 s after 400 cd/m2, 200 ms blue light stimuli. The comparison of MPCs (mean±SD) is plotted in Fig. 1.

ABSTRACT

We collected and analyzed pupil diameter data from of 7 visually normal participants to compare the maximum pupil constriction (MPC) induced by &ldquo;Red Only&rdquo; vs. &ldquo;Blue+Red&rdquo; visual stimulation conditions.

The &ldquo;Red Only&rdquo; condition consisted of red light (640&plusmn;10&nbsp;nm) stimuli of variable intensity and duration presented to dark-adapted eyes with pupils at resting state. This condition stimulates the cone-driven activity of the intrinsically photosensitive retinal ganglion cells (ipRGC). The &ldquo;Blue+Red&rdquo; condition consisted of the same red light stimulus presented during ongoing blue (470&plusmn;17&nbsp;nm) light-induced post-illumination pupil response (PIPR), representing the cone-driven ipRGC activity superimposed on the melanopsin-driven intrinsic activity of the ipRGCs (&ldquo;The Absence of Attenuating Effect of Red light Exposure on Pre-existing Melanopsin-Driven Post-illumination Pupil Response&rdquo; Lei et al. (2016) [1]).

MPC induced by the &ldquo;Red Only&rdquo; condition was compared with the MPC induced by the &ldquo;Blue+Red&rdquo; condition by multiple paired sample t-tests with Bonferroni correction.
