Improving preschool vision screening programs.

Early detection of amblyopia is important, but many preschool-aged children do not receive vision screening. Factors that account for missed opportunities in detecting vision problems in early childhood include the difficulty of evaluating vision in an uncooperative child or in an infant and toddler. Methods need to be found to improve the low rate of preschool vision screening. In Missouri, a study has begun on preschool vision screening to find the most cost-effective method.
