ABSTRACT: The VIP Study is a prospective, multi-center, interdisciplinary clinical study to establish the accuracy of tests to screen for significant vision disorders among 3- and 4-year-old Head Start preschoolers. The 5-year study funded by NEI targets 10,000 preschoolers at 5 clinical centers across the U.S. The overall goal of the study is to determine whether a single vision screening test or combination of tests can be used effectively to determine which preschoolers would benefit from a comprehensive eye examination. Vision disorders targeted for detection in the study are amblyopia, strabismus, and significant refractive error.
The goal of Phase I is to determine which of the following tests, performed by Licensed Eye Care Practitioners (optometrists and ophthalmologists), are useful in screening the vision of preschoolers: Monocular Visual Acuity, Stereoacuity, Cover/Uncover Test, Noncycloplegic Retinoscopy, Autorefraction. Licensed Eye Care Practitioners who are masked to the results of the screening will complete the Gold Standard Eye Examination of the preschoolers to determine whether a screening test is accurate. Activities in Phases II and III of the VIP Study are aimed at determining whether school nurses or lay screeners can effectively use the screening tests to identify those preschoolers who require further vision care for amblyopia, strabismus, and/or significant refractive error.
