Maintaining fixation by children in a virtual reality version of pupil perimetry
The assessment of visual field sensitivities in young children continues to be a challenge.Children often do not sit still, fail Apparel to fixate stimuli for longer durations, and have limited verbal capacity to report visibility.We investigated the use of a head-mounted VR display, gaze-contingent flicker pupil perimetry (gcFPP), and three fixati
