Cerebral Visual Impairment (CVI) constitute a set of visual function disorders of cerebral origin. Autism spectrum disorders (ASD) are neurodevelopmental disorders characterized by difficulties in communication and social interactions, as well as restricted interests, repetitive, and stereotyped behaviors. Nearly 90% of autistic individuals exhibit sensory peculiarities, which have been included in the diagnosis of ASD since 2013.
Thus, specificities of the visual system are observed in these two neurodevelopmental disorders (ASD and CVI), yet the incidence of CVI and particularly visual fixation disorders, is currently unknown in the autistic child population.
Visual fixation is a determining factor for the acquisition of visual information, for exploring the environment, for social interactions, and communication, functions disrupted in ASD. Considering the impact of perceptual disorders, particularly visual fixation disorders, on the overall behaviors and cognitive capacities of this clinical population is therefore necessary to adjust diagnosis and management.
