Abstract
Abstract Purpose To examine the effects of concussion history on baseline pupillometry assessment in collegiate athletes. Method A total of 82 (age= 20.04±1.2 years) collegiate athletes, consisting of 56 males (68.3%) and 26 females (31.7%), completed a baseline pupillometry assessment. Left and right eye trials were averaged together for an average score of each measure. Measures consisted of % change (DELTA) of initial to end pupil constriction, latency of constriction (LAT) in seconds, average (ACV) and maximum constriction velocity (MCV) in mm/s. Concussion history groups were dichotomously categorized as those with (n= 30, 36.6%) or without a prior diagnosed concussion (n=52, 63.4%) and a dose-response of those with 1 (n=18) or 2+ (n=12) prior diagnosed concussions. A series of Mann-Whitney U tests were used to compare measures between groups. Results There were no significant differences between athletes with and without a concussion history on baseline DELTA (37.58±4.2 vs. 38.59±4.4%; U=699.5, p=0.438), LAT (0.21±0.0 vs. 0.23±0.s; U=601.5, p=0.076), ACV (-2.96±0.3 vs. -3.02± 0.4 mm/s; U=674.0, p=0.307), or MCV (-4.56±1.1 vs. -4.83±0.6 mm/s; U=684.0, p=0.355). Further, no dose-response differences existed between athletes with one and multiple prior concussions for DELTA (38.36±4.5 vs. 36.41±3.6%; U=76.5, p=0.185), LAT (0.21±0.0 vs. 0.21±0.0s; U=100.5, p=0.755), ACV (-3.02±0.4 vs. -2.88±0.2 mm/s; U=73.5, p=0.146), or MCV (-4.57±1.4 vs. -4.55±0.5 mm/s; U=84.0, p=0.325). Conclusions Concussion history did not appear to influence baseline pupillometry assessment in collegiate athletes. It is possible that altered pupillary light reflex metrics may not extend beyond concussion recovery or remain present long-term.
