National Vision & Eye Health Surveillance System

National Vision & Eye Health Surveillance System
CDC’s Vision Health Initiative has established a 4-year cooperative agreement with the National Opinion Research Center (NORC) at the University of Chicago to develop a vision and eye health surveillance system for the nation.

The goals of the project are to

  • Identify and acquire existing sources of information on vision and eye health.
  • Create case definitions for vision and eye conditions and analytic algorithms to apply these definitions in a consistent and uniform manner across data sources.
  • Analyze sources of information to estimate
    • Prevalence of eye disorders and disabilities.
    • Use of eye-health services.
    • Disparities in visual health treatment and outcomes.
  • Document the development of the surveillance system through peer-reviewed publications.
  • Disseminate the information developed by the project to the public through peer-reviewed publications and Internet-enabled resources.

To achieve these goals, NORC has partnered with University of Wisconsin, Prevent Blindness, Vision Service Plan, and HIV Counts. NORC also collaborates closely with professional organizations and stakeholders such as the American Academy of Ophthalmology and the American Optometric Association.

Several data sources will be evaluated for inclusion in the system such as national survey data, longitudinal population-based studies, registry data, electronic health records, and administrative claims records. The project will use advanced statistical methodologies to estimate eye condition prevalence values from each contributing data source, and to summarize and integrate estimates across sources. Examples of data analysis and integration methodologies planned for the project include logistic and multivariate regression, meta-analysis, small area estimation, Bayesian simulation, and data imputation modeling. An expert advisory panel will monitor major project development milestones.

The project includes a broad strategy for communication and dissemination of outcomes as well as engagement sessions and outreach activities to facilitate the participation of stakeholders. Major project outcomes will be released through study-group authored publications in the peer-reviewed literature. Development of an interactive website will allow widespread dissemination of detailed surveillance system outcomes to the public.
