ABSTRACT
PURPOSE: To describe the use of photoscreening for preschool vision screening in several diverse locations throughout the world. METHODS: The MTI photo screener was used to screen pre-verbal children; photographs were interpreted using standard criteria. RESULTS: The Tennessee vision screening program remains successful, screening over 200,000 children during the past 8 years. Similar programs modeled across the United States have screened an additional 500,000 children. A pilot demonstration project in Hong Kong, Beijing, and Brazil screened over 5000 additional children with good success and appropriately low referral rates. CONCLUSION: Photoscreening can be an appropriate technique for widespread vision screening of preschool children throughout the world.
