Insights
Children with congenital blindness, such as Leber's congenital amaurosis (LCA), rarely have autism. Early intervention can help visually impaired children with social interaction challenges.
Area of Science:
- Ophthalmology
- Developmental Psychology
- Neuroscience
Background:
- Evidence suggests a link between congenital blindness and autistic-like features.
- The clinical significance of this association remains unclear.
- Vision plays a crucial role in child development.
Purpose of the Study:
- To investigate the significance of autistic-like behaviors in children with early-onset severe visual impairment.
- To determine if Leber's congenital amaurosis (LCA) is associated with genuine autism.
- To identify potential risks and interventions for visually impaired children.
Main Methods:
- Studied 24 children (mean age 5y 2mo) with Leber's congenital amaurosis (LCA).
- Administered a modified Childhood Autism Rating Scale, excluding visual responsiveness.
- Assessed social and emotional responsiveness and interpersonal relationships.
Main Results:
- Only 4 out of 24 children scored positive for mild/moderate autism.
- Most children with LCA did not exhibit major social or emotional dysfunctions.
- Genuine comorbidity with autism was excluded in the LCA sample.
Conclusions:
- Autistic-like behaviors in children with LCA are not indicative of true autism.
- Visually impaired children face risks related to early interactive experiences.
- Specific intervention strategies can mitigate challenges in social connection for visually impaired children.
Abstract:
There is much evidence in the literature suggesting that children with congenital blindness can also present autistic like features. The aetiopathogenetic and clinical significance of this association is still unclear. Given the central role played by vision in development, we set out to establish the significance of autistic-like behaviours in children with early-onset severe visual impairment. Our sample comprised 24 children (13 males, 11 females; mean age 5y 2mo; range 2-11y) affected by Leber's congenital amaurosis (LCA). The results of our administration of a modified Childhood Autism Rating Scale--excluding item VII (Visual Responsiveness)--showed that only four of the children gave an overall score indicating the presence of autism (moreover, of mild/moderate degree). Hardly any of the children in our LCA sample presented major dysfunctions in their relationships with other people or in their social and emotional responsiveness, thus allowing us to exclude a genuine comorbidity with a picture of autism. Indeed, the risk facing the visually impaired child seems to concern their early interactive experiences, which may be affected by their inability to connect with others, and may be prevented through the development of specific strategies of intervention.
