National survey of paediatric vision screening programs across Canada: Identifying major gaps and call to action

Paediatric vision screening programs identify children with ocular abnormalities who would benefit from treatment by an eye care professional. A questionnaire was conducted to assess existence and uptake of school-based vision screening programs across Canada. A supplementary questionnaire was distributed among Ontario's public health units to determine implementation of government mandated vision screening for senior kindergarten children.

Chief Medical Officers of Health for each province and territory, and Ontario's thirty-four public health units were sent a questionnaire to determine: 1) whether school-based vision screening is being implemented; 2) what age groups are screened; 3) personnel used for vision screening; 4) the type of training provided for vision screening personnel; and 5) vision screening tests performed.

Of the thirteen provinces/territories in Canada, six perform some form of school-based vision screening. Two provinces rely solely on non-school-based programs offering eligible children an eye examination by an optometrist and three rely on ocular assessment conducted by a nurse at well-child visits. In Ontario, where since 2018 vision screening for all senior kindergarten students is government mandated, only seventeen public health jurisdictions are implementing universal vision screening programs using a variety of personnel ranging from food safety workers to optometrists.

Good vision is key to physical and emotional development. There is an urgent need for a universal, evidence-based and cost-effective multidisciplinary approach to standardize paediatric vision screening across Canada and break down barriers preventing children from accessing eye care.
