Congenital blindness and autism spectrum disorder (ASD): diagnostic challenges and intervention options

The case of a 6-year-old boy with congenital blindness and features suggestive of autism spectrum disorder (ASD) is reported. He presented to a developmental paediatrician with global developmental delay, worsening self-injurious behaviours and difficulties in social interaction, transitions and interactive play. He demonstrated poor response to his name, rigidity, repetitive behaviours and had a sensory profile suggestive of ASD. This paper discusses the challenges in diagnosing and managing ASD in visually impaired children.
