Current Projects

Extramural Research

Currently, through a new cooperative agreement with Prevent Blindness America (PBA), our funding and technical assistance continues to help raise the awareness of vision loss and eye diseases within the nation. This cooperative agreement will help to develop a community model to reach high risk population, develop a model to integrate vision health activities within existing state public health programs, and enhance the surveillance system.

Economic Studies

• The multiple eye disease simulation model (MEDS)
• Economic burden of eye diseases and visual impairment in adult Americans

National and State Based Surveillance Studies

• NHANES —- Vision Examination and Opthalmology Components
  The Vision Examination data in NHANES are used to measure the prevalence of visual acuity impairment (visual acuity worse than 20/40) in the U.S. population; measure the distribution of refractive error in the U.S. population; and evaluate functional impairment related to vision. Read More
• State-Based Behavioral Risk Factor Surveillance System (BRFSS) Visual Impairment and Access to Eye Care Module
  Since 2005, 20 states have been funded by VHI through agreements with National Association of Chronic Disease Directors (NACDD). In response to Healthy People 2010 vision objectives, these state-based surveys aim to develop and enhance a surveillance system for vision loss and eye diseases to assess burden and health disparity and to monitor national and state trends.
