Abstract

Methods
34 children with CVI (≤ 12 years old) and 29 age-matched controls were recruited. Participants viewed a series of images on a computer monitor while direction of eye gaze was recorded. We excluded participants whose visual acuity was insufficient to resolve images on the screen, based on Fourier analysis to calculate the spatial frequency of these images. SegCLIP generated saliency maps of each image, highlighting areas of interest pertaining to specific visual characteristics. Fixations were aligned to these saliency maps to calculate fixation saliency values, which were compared between CVI and control participants.
Results
Mean age was 4.9 years, and mean binocular visual acuity was 8.9 cpd by preferential looking. Compared to age-matched controls, CVI participants fixated less on human faces, 2-dimensional representations of depth, still depictions of motion, and visually complex stimuli (< 0.001).
