Vision screening of school children in greenland 2017-2022: coverage and low vision prevalence.

Vision screening during childhood is vital for the early detection and treatment of visual impairment that may significantly impact a child's development and quality of life. This nationwide cross-sectional study used data from Greenland's national electronic medical records, including 2,493 six-year-old children from July 2017 to July 2023, to evaluate the coverage rate of vision screening and the prevalence of low vision in Greenlandic schoolchildren. The participation rate in vision screening increased from 43% in 2017 to 61% in 2022, while referral rates to ophthalmologists decreased from 14% to 5%, despite a consistent prevalence of low vision.
