Purpose: The validity of preschool vision screening has been questioned in the light of the World Health Organization's criteria for determining the validity of screening programs. However, recommendations toward preschool screening have been made by a number of organizations. Given the contrasting views of screening, the purpose of this study was to examine visual health care provider experiences and attitudes toward preschool screening.
Method: Optometrists, public health administrators, pediatric ophthalmologists, and orthoptists were surveyed about opinions of, recommendations for, and experiences with preschool vision screening in Ontario. The survey focused on four areas, including general opinion of preschool screening, screening standards and practices, provider experience with preschool screening, and barriers to preschool screening. In addition, survey responses were broken down by regional access to health care.
Results: Overall, strong support for preschool vision screening and movement toward standardization of screening practice was found among all surveyed groups. Although support for vision screening in low health care access areas was strong, providers estimated that parent compliance to screening was weaker in low access areas. Providers also reported considerable variability in vision screening practices. In addition, although the majority of providers had been involved in a screening program, the majority was no longer involved because of lack of program organization, structure, and funding. Lack of sufficient funding, public education, organization of screening, training, and government support were listed as barriers to preschool vision screening.
Conclusion: Providers are interested in the development of structured screening programs. However, although screening may be a way to offer some level of vision care service to low health care access areas, a number of factors need to be addressed in discussions of vision screening program standards or screening best practice. In general, preschool screening programs need to be structured, be supported, have quality control, and be evaluated.
