Study Notes

Visual Impairment and Blindness in Childhood

Visual impairment (VI) is a severe or total reduction in vision, often uncorrectable with standard eyewear.
Globally, 19 million children experience VI, with 1.4 million being blind.
Incidence in the UK is approximately 2 in 1000, often from birth.
75% of cases in the UK are not preventable or treatable.
Increased risk for children born prematurely, with brain damage or genetic syndromes associated with eye abnormalities.
Often associated with additional impairments or chronic conditions (over 75%).
Isolated VI increases risk of developmental delay.

Role of Vision in Development

Vision guides the coordination and understanding of spatial relationships between objects and the self.
Babies show visual preferences as early as 30 minutes old for faces.
Infants of 2-5 days have specific responses to faces, making eye contact.
Key developmental milestones are affected by vision, including:
- Object permanence
- Joint attention
- Imitation
- Pretend play
- Language and communication

Autism in Children with Visual Impairment

Autistic presentation can occur in children with VI, as it does in sighted children.
Differences in prevalence, severity and natural history may exist between blind and sighted children with autism.
Some children with VI may "outgrow" autism-like traits over time.
Heterogeneity and qualitative differences are observed in developmental outcomes for blind children.

Assessment and Diagnostic Considerations

Existing tests for ASD often aren't suitable for VI children, relying on visual stimuli.
Testing and assessment procedures should be adapted to consider sensory impairment.
Professionals with expertise in both blind children's development and ASD are needed for accurate diagnosis.
Interventions should be tailored to the child's unique needs.

Brain Plasticity and Compensatory Mechanisms

Visual cortex adapts to other functions in the absence of visual input
Language and auditory abilities often compensate for lost visual function.
Auditory advantage has been observed in blind children, including echolocation and absolute pitch.

Savant Syndrome

Savant syndrome is characterized by unusual skills (e.g., music, art, math) in individuals with developmental disabilities or brain disorders.
Blindness is sometimes associated with musical abilities and savant abilities in general.
