Abstract:
Objective To analyze the visual acuity and refractive status of kindergarten children and primary and middle school students in Xinhong Community of Shanghai from 2015 to 2018, and to provide basis and reference for the prevention and control of students' myopia. Methods The data of 3 904 person-times of complete visual acuity and refraction records from 2015 to 2018 was derived from the "Shanghai Residents' Eye Health Information Service System". Results From 2015-2018, the total detection rate of poor vision of kindergarten children and primary and middle school students was 60.86%, and the detection rate of poor vision in kindergarten, primary school and middle school was 29.90%，62.63% and 87.26% respectively，showing an increasing trend with the education stage (χ2=727.206，P<0. 05). The detection rate of poor vision in boys was 57.31%, and that of girls was 64.29% (χ2=19.949, P<0.05). According to the classification of the degree of visual impairment, the peak stage of mild poor vision was in grade one to three of primary school, the peak stage of moderate poor vision was in grade four and five of primary school, the peak stage of severe poor vision was in middle school, and the highest peak of poor vision in second grade of middle school, accounting for about 70.85%. The total detection rate of poor vision with glasses reached 18.21%. The total detection rate of myopia in refractive state was 54.79%, and the detection rate of myopia in kindergarten, primary school and middle school were 16.27%,56.61% and 88.28% respectively, showing an increasing trend with the education stage (χ2=1099.978, P<0.05). In terms of growth rate, the increase in myopia in the first grade of primary school was the largest. Conclusion The myopia rate of primary and secondary school students was higher than that of kindergarten children, and showed an increasing trend with the education stage. The critical period of myopia prevention and control should be advanced to the kindergarten stage.
