Purpose: The aim was to study visual perception changes based on eye-tracking data assessments in response to transcranial photobiomodulation (t-PBM) in young, healthy subjects.
Material and Methods: Our non-randomized single-center study involving 53 young, healthy volunteers (22 men and 31 women). The eye tracking procedure (EyeTracker, BVG Software Group LLC, CA, USA) was carried out before and immediately after t-PBM (Elmedlife H, RF). Data were expressed as a median [interquartile range]. Statistical analysis was performed using the T- criterion Wilcoxon. The significance level was preset p < 0.05.
Results: Vertical vergence reactivity indexes (VRx) after t-PBM were significantly higher than before 0.881 [0.841; 0.914] vs. 0.784 [0.711; 0.832], p < 0.05, respectively. Horizontal VRx before t-PBM were significantly lower than after t-PBM 0.893 [0.822; 0.935] vs. 0.920 [0.917; 0.929], p < 0.05.
Conclusion: Transcranial PBM improves visual perception in young, healthy volunteers, as reflected by a significant increase in both vergence reactivity indices.
