Concussion Alters Dynamic Pupillary Light Responses in Children.
Journal of Child Neurology 2021 March
AIM: To investigate the impact of concussion on pupillary function in children by examining pupillometric parameters and assessing for differences in children reporting photosensitivity.
METHODS: Retrospective chart review was performed of pediatric patients referred for visual symptoms after concussion from 2017 to 2018 seen in a single academic outpatient clinic. Pupillometry data of 92 patients were included. Outcomes were compared to normative pediatric data from the same institution by 2-sample t tests. The association between photosensitivity and each outcome was assessed by use of linear mixed models with photosensitivity as a fixed effect and random patient effect.
RESULTS: Outcomes of 181 eyes in 92 concussion patients were averaged by patient and compared to normative values in scotopic conditions. Concussion patients had an average age of 13.8 ± 2.64 years. Average constriction velocity ( P = .0008), maximum constriction velocity ( P = .0012), and average dilation velocity ( P = .0034) were faster in concussion patients, whereas 75% recovery times ( P = .0027) was increased. Photosensitivity did not significantly affect measured pupillary responses.
CONCLUSION: Dynamic pupillary responses may be increased in pediatric concussion. Pupillometry may provide insight into the complex pathophysiological changes underlying pediatric concussion.
