Objectives: This study compares wearing time for four months after receiving a new spectacle correction in subjects within Autism Spectrum Disorder (ASD) population to typically developing (TD) children and adolescents age 9 to 17 years old. Methods: Children and adolescents who were ASD or TD were enrolled from subjects recruited from another pilot study focused on eye examination testing for children and adolescents with ASD. A psychologist determined group status/ eligibility using American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-Text Revision (DSM-IV-TR) criteria after review of previous evaluations and parent report of symptomology on the Social Communication Questionnaire. Parents provided the subject's age, level of parent education, gender, race, ethnicity and urbanization level. Parents completed a telephone survey at 1, 2, 4, 8, 12, and 16 weeks after the child received their spectacles. The survey asked questions about wearing time, willingness to wear spectacles and amount of prompting required. Data was analyzed to determine if there were differences between the ASD and TD group. Results: 22 subjects were enrolled who met review criteria for ASD or TD group and needed refractive correction. No significant difference was found between ASD and TD wearing time (p > 0.05). Age, gender, ethnicity, level of parent education, urbanization level and grade in school did not demonstrate differences in adaptation between the TD and ASD groups. Conclusions: Parental reports of wearing time and resistant behavior demonstrate that children and adolescents with ASD adapt to spectacle wear for significant refractive error similarly to typical children and adolescents.

Yes / Objectives: To determine the impact of adherence to spectacle wear on visual acuity (VA) and developing literacy following vision screening at age 4–5 years. Design: Longitudinal study nested within the Born in Bradford birth cohort. Setting and participants: Observation of 944 children: 432 had failed vision screening and were referred (treatment group) and 512 randomly selected (comparison group) who had passed (<0.20 logarithm of the minimum angle of resolution (logMAR) in both eyes). Spectacle wear was observed in school for 2 years following screening and classified as adherent (wearing spectacles at each assessment) or non-adherent. Main outcome measures: Annual measures of VA using a crowded logMAR test. Literacy was measured by Woodcock Reading Mastery Tests-Revised subtest: letter identification. Results: The VA of all children improved with increasing age, −0.009 log units per month (95% CI −0.011 to −0.007) (worse eye). The VA of the adherent group improved significantly more than the comparison group, by an additional −0.008 log units per month (95% CI −0.009 to −0.007) (worse eye) and −0.004 log units per month (95% CI −0.005 to −0.003) in the better eye. Literacy was associated with the VA, letter identification (ID) reduced by −0.9 (95% CI −1.15 to −0.64) for every one line (0.10 logMAR) fall in VA (better eye). This association remained after adjustment for socioeconomic and demographic factors (−0.33, 95% CI −0.54 to −0.12). The adherent group consistently demonstrated higher letter-ID scores compared with the non-adherent group, with the greatest effect size (0.11) in year 3. Conclusions: Early literacy is associated with the level of VA; children who adhere to spectacle wear improve their VA and also have the potential to improve literacy. Our results suggest failure to adhere to spectacle wear has implications for the child’s vision and education. / AB is funded by a National Institute for Health Research Post- Doctoral Fellowship Award (PDF-2013-06-050).
