This study mainly investigated the incidence of eye diseases in children with autism spectrum disorder(ASD) in Tianjin area, and analyzed related risk factors, so as to raise attention to eye diseases in children with ASD. To evaluate the impact of ophthalmic treatment on the quality of life of children with autism and their primary caregivers.

In recent years, the incidence of autism has increased year by year, which has brought a heavy burden to society and families. For the special group of children with autism spectrum disorder, previous studies focused on the lack of comprehensive and accurate visual function characteristics and defects of this group. In the early stage, it was believed that there was a certain correlation between visual impairment and autism, and some patients with visual impairment were misdiagnosed as autism. Moreover, some studies have shown that the incidence of refractive errors and oblique amblyopia in autistic children is significantly higher than that in normal children. This study mainly includes two parts: On the one hand, investigate the autism children in Tianjin area to understand the incidence of eye diseases. On the other hand, children with eye problems were given relevant interventions, such as optometry, amblyopia training, strabismus surgery, etc., to assess the impact of the corresponding treatment on the quality of life of the children and their primary caregivers.
