Abstract
Purpose: :
This study documents the characteristics of and pilots a model for implementing preschool vision screening in Ohio based on trained lay volunteers using tests that performed best in the Vision In Preschoolers (VIP) Study.
Methods: :
The 88 Ohio counties were surveyed to establish preschool vision screening practices: 1) tests used, 2) screening personnel, and 3) numbers of children referred. Further, in collaboration with the OSU Extension Program and The Ohio State University Office of Outreach, a model for implementing community-based preschool vision screening programs with high school age youth (4-H Youth Leaders, 13-19 years) was tested and refined using the best screening practices from the VIP Study (tests, testers, protocols, referral criteria, disorder definitions, educational materials).
Results: :
Responses received from 52% (n=46) of Ohio counties show that in community-based preschool vision screening programs: 1) visual acuity and eye alignment are tests most frequently used; 2) nurses most frequently administer tests; 3) 1-34% of Ohio children are referred from screenings. Of the 4-H Youth Leaders trained to conduct the SureSight Vision Screener, Retinomax Autorefractor, and Crowded Singular Lea Symbols Visual Acuity (5 Foot) screening tests, more than 95% (20/21) were able to complete certification requirements similar to those used in the VIP Study and to implement community-based preschool vision screening programs.
Conclusions: :
Tests which peformed best in the VIP Study are not in use in Ohio. Statewide preschool vision screening referral rates vary more than the rates reported nationally (4-17%). Trained high school students show excellent potential and enthusiasm for implementing community-based preschool vision screenings using a model viewed as service and learning programs ideal for 4-H Youth.
