Chang MY, Doppee D, Yu F, et al. - Researchers conducted this population-based retrospective cohort study to calculate the prevalence of ophthalmologic disorders in children with autism spectrum disorder (ASD). Between 2007 to 2013, children less than or equal to 18 years of age at the time of the first claim were analyzed. Claims from over 10 million children have been involved. In this study, the prevalence of any ophthalmologic diagnosis (amblyopia, strabismus, optic neuropathy, nystagmus, or retinopathy of prematurity) was 3.5% in typically developing controls, 12.5% in children with PDD, and 13.5% in children with autistic disorder. Population-based data indicate an increased risk of ophthalmologic diagnoses in ASD children. The relationship between ophthalmologic disorders and autistic symptoms and severity needs to be further clarified in future research.
