Visual Impairment and Autism Spectrum Disorder in Young Children

Visual impairment and autism spectrum disorder (ASD) often intersect in early childhood, presenting a complex clinical picture that challenges diagnosis, intervention and long-term support. Children with congenital or acquired visual deficits may display behaviours—such as limited eye contact, reduced social reciprocity or repetitive movements—that overlap with core features of ASD, leading to potential misdiagnosis or delayed recognition of one or both conditions. Impaired vision disrupts access to non-verbal cues, facial expressions and joint attention, which are critical for typical social and language development. In turn, autistic traits can mask underlying ocular pathology or compromise engagement with visual rehabilitation. A nuanced understanding of sensory processing, neural plasticity and developmental trajectories is therefore essential. Early, multidisciplinary assessment that combines ophthalmological, behavioural and neurodevelopmental evaluation can differentiate primary visual disorders from autistic features and guide tailored interventions. Globally, improved screening protocols and integrated support frameworks are being adopted to ensure that young children with this dual vulnerability receive timely therapeutic input, parent coaching and educational adaptations that promote optimal cognitive, communicative and social outcomes.

Visual Impairment and Autism Spectrum Disorder in Young Children publication trend

The graph below shows the total number of articles in visual impairment and autism spectrum disorder in young children across all publications each year (not limited to Nature Index journals).

Technical terms

Autism Spectrum Disorder: A neurodevelopmental condition characterised by difficulties in social interaction, communication and repetitive or restricted behaviours.

Visual Impairment: A broad term covering reduced visual acuity or visual field loss that cannot be corrected fully by refractive means.

Visual Acuity: The sharpness of vision, often measured by the ability to discern letters or symbols at a fixed distance.

Refractive Error: Optical defects of the eye (such as myopia, hyperopia or astigmatism) that prevent light from focusing clearly on the retina.

Strabismus: A misalignment of the visual axes of the eyes, commonly known as squint.

Amblyopia: Reduced vision in one eye due to disuse during early development, often called “lazy eye.”
