Summary
Children with cerebral/cortical visual impairment (CVI) show significantly reduced adaptive functioning. Visual behavior is linked to socialization and daily living skills, suggesting potential for improvement with better visual acuity.
Area of Science:
- Pediatric ophthalmology
- Neuroscience
- Developmental psychology
Background:
- Cerebral/cortical visual impairment (CVI) is a primary cause of pediatric vision loss in developed nations.
- CVI is linked to neurological conditions impacting daily adaptive skills like communication and socialization.
- Adaptive behavior in CVI has been understudied, with its relationship to visual function unknown.
Purpose of the Study:
- To systematically investigate adaptive behavior in children with CVI.
- To determine the relationship between visual function and adaptive behavior in this population.
Main Methods:
- Prospective recruitment of 49 children with CVI (mean age 4 ± 3 years).
- Adaptive behavior assessed using the Vineland Adaptive Behavior Scale, 3rd edition (VABS-III).
- Visual acuity evaluated via the six-level Visual Behavior Scale (VBS); statistical analysis included Spearman correlation and multiple regression.
Main Results:
- Children with CVI exhibited mean VABS-III scores below the 1st percentile across all domains.
- VBS scores significantly correlated with VABS-III total adaptive behavior composite score, socialization domain, and interpersonal, play/leisure, and personal subdomains.
Conclusions:
- Children with CVI demonstrate substantially impaired adaptive functioning.
- Visual behavior is associated with socialization and specific daily living skills.
- Further research should explore if improved visual acuity correlates with enhanced adaptive functioning in CVI, potentially aiding prognosis.

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...

174
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

01:24Vision
52.9K
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.

5.6K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

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.
