Significance: Vision problems occur at higher rates in children with autism spectrum disorder (ASD) than in the general population. Some professional organizations recommend that children with neurodevelopmental disorders need comprehensive assessment by eye care professionals rather than vision screening.
Methods: Data from the 2011 to 2012 National Survey of Children's Health (NSCH) were accessed.
Purpose: To investigate practices, barriers, and facilitators of universal pre-school vision screening (PVS) at pediatric primary care offices.
Methods: Focus group sessions (FGS) were moderated on-site at nine pediatric practices. A semi-structured topic guide was used to standardize and facilitate FGS.
Objective: To determine whether age at initiation of treatment for amblyopia influences the response among children 3 to less than 13 years of age with unilateral amblyopia who have 20/40 to 20/400 amblyopic eye visual acuity.
Methods: A meta-analysis of individual subject data from 4 recently completed randomized amblyopia treatment trials was performed to evaluate the relationship between age and improvement in logMAR amblyopic eye visual acuity. Analyses were adjusted for baseline amblyopic eye visual acuity, spherical equivalent refractive error in the amblyopic eye, type of amblyopia, prior amblyopia treatment, study treatment, and protocol.
Purpose: To evaluate knowledge, attitudes, and environment of primary care providers, and to develop a conceptual framework showing their impact on self-reported pre-school vision screening (PVS) behaviors.
Methods: Eligible primary care providers were individuals who filed claims with Medicaid agencies in Alabama, South Carolina, or Illinois, for at least eight well child checks for children aged 3 or 4 years during 1 year. Responses were obtained on-line from providers who enrolled in the intervention arm of a randomized trial to improve PVS.
