Summary
Early visual system development in autism spectrum disorder (ASD) shows atypical patterns linked to genetic factors. Understanding these early visual changes is key to unraveling ASD
Area of Science:
- Neurodevelopmental disorders
- Autism Spectrum Disorder (ASD)
- Visual System Development
Background:
- Longitudinal neuroimaging reveals atypical visual system development in early childhood in ASD.
- Genetic factors are implicated in visual system alterations in ASD, highlighting it as a key neural phenotype.
- The visual system's development is crucial for understanding the trajectory from genes to behavior in ASD.
Purpose of the Study:
- To review current knowledge on visual system development in ASD during early life.
- To explore the role of atypical visual system maturation in the emergence of ASD.
- To contextualize findings within developmental cascades involving brain, attention, and socio-cognitive development.
Main Methods:
- Review of longitudinal neuroimaging studies.
- Integration of findings from genomic analyses, family studies, and postmortem investigations.
- Developmental cascade model contextualization.
Main Results:
- Evidence suggests early-life atypical visual system development in ASD.
- Genetic factors contribute to these visual system changes.
- Atypical visual maturation may influence developmental cascades impacting ASD.
Conclusions:
- The developing visual system in ASD is a critical area for further research.
- Addressing gaps in understanding early visual development is essential for comprehending ASD.
- Future research should focus on early brain development's role in ASD etiology.

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

01:31What is a Sensory System?
93.1K
Sensory systems detect stimuli—such as light and sound waves—and transduce them into neural signals that can be interpreted by the nervous system. In addition to external stimuli detected by the senses, some sensory systems detect internal stimuli—such as the proprioceptors in muscles and tendons that send feedback about limb position.

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

609
The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.
