Autism and Visual impairment: A First Approach to a Complex Relationship.

Since the first half of the 20th century there has been an interest in the study of the relationship between autism and autistic-like clinical features and with visual impairments. Autism Spectrum disorders are one of the more worldwide-studied neurodevelopmental disorder with an increasing prevalence in the last ten years. Visual impairment is a condition which derives from several causes (genetic, constitutional, injuries, nutritional and environmental ones). Again, it is a kind of spectrum and an overarching category, because visual impairments range from refractive errors (myopia, hyperopia, astigmatism), to amblyopia, strabismus, and to partial and total blindness. Since the first study of Keeler (1956) which described autistic-like patterns in five preschool children who were totally blind due to retinopathy of prematurity (ROP), a growing number of researchers addressed the relationship between autism and visual impairment. In this paper we focused on it, aiming to discuss on some lessons learned in this field and to discuss some open questions since the first research in this field.

Children with autism spectrum disorders and severe visual impairments: Some general principles for intervention according to the perspective of clinical psychology of disability.

In the last decades, an increasing number of researchers addressed the relationship between autism spectrum disorders (ASD) and severe visual impairment (SVI) (like blindness or very low visual acuity) and nowadays autism could be considered one of the most reported coexisting developmental disorders in children with blindness or other severe visual impairment. As ASD and SVI' signs and symptoms affect functioning and quality of life and different domains of functioning of children with this comorbidity, it is very important to support individuals and their families as soon as possible in the cycle of life and to promote specific interventions aimed to promote developmental potential of everyone with both ASD and VI, based on the unique balance between strengths, needs and abilities of everyone. Children and individuals with SVI and ASD and SVI are a very heterogeneous group, both about the areas of social interaction, communication, and behaviour, as well as about visual abilities and about all the other aspects of their neuropsychological and functional profiles that are influenced by their visual impairments itself, their ASD itself and the combination of them. In this paper, we aim to discuss some general principles useful to design and to develop specific interventions and to promote inclusion of children with ASD and SVI.
