Autism spectrum disorder (ASD) is increasingly prevalent, estimated to occur in 1.68% of children in the United States, yet there are few data on ophthalmic co-morbidities in this population. The purpose of this study is to characterize risk factors and types of ophthalmologic disorders represented in children with ASD.
We conducted a retrospective chart review of all children (0-17 years old) with an ICD diagnosis of ASD seen at a single university over a 10-year period (2007-2017). In patients evaluated at the university eye clinic, demographic data, birth history, co-morbidities, and ophthalmologic findings were recorded. Multiple logistic regression was used to identify risk factors for ophthalmologic disorders.
2,555 children with ASD were seen at the university during this time period, and 380 (15%) were evaluated in the ophthalmology clinic. Eye exam revealed an ophthalmic diagnosis in 71% of children, of which the most common were significant refractive error (42%), strabismus (32%), and amblyopia (22%). Optic neuropathy occurred in 14 (4%) children. Cerebral palsy (CP) was a significant risk factor for refractive error (OR 3.22, p=0.016), strabismus (OR 3.59, p=0.012), amblyopia (OR 3.49, p=0.0097), and optic neuropathy (OR 14.0, p=0.0009).
Ophthalmic disorders occurred in 71% of children with ASD, and the rates of significant refractive error, amblyopia, strabismus, and optic neuropathy exceeded those of the general pediatric population. ASD and CP may have additive risk for the aforementioned disorders. Prospective studies are necessary to further characterize the possible association between ASD and ophthalmic pathology. Pediatric ophthalmology referral should be considered in children with ASD.
