Reports on the relationship between freezing of gait (FoG) and visual search behavior in Parkinsonian syndrome remain limited. This study aimed to examine gaze behavior in three patients with progressive supranuclear palsy during doorway walking trials. Contrary to previous case reports, substantial individual variability was observed in gaze fixation patterns and blink rates during the FoG episodes. In conclusion, the relationship between visual search behavior and freezing is more complex than previously understood.
