Abstract:
AIM: To investigate the myopia and hyperopia reserve among Uyghur children aged 6～12 in Yecheng county of Xinjiang.METHODS: In a cross-sectional study, a total of 50 151 Uyghur students aged 6～12 years from Yecheng county of Xinjiang underwent comprehensive vision screening, including automatic computer optometry, indoor remote light box E-word standard logarithmic visual acuity chart(GB 11533), to measure the naked eye distant vision and corrected vision with lens.RESULTS: From October 2021 to January 2022, the spherical equivalent(SE)of 6-12 year old Uyghur myopic children was -0.875(-1.625, -0.625)D, and the detection rate of myopia was 6.75%(3384/50151)in Yecheng county of Xinjiang. The SE of the myopic children aged 6～12 was -0.75(-1.125, -0.625)D, -0.75(-1.125, -0.625)D, -0.875(-1.125, -0.625)D, -0.875(-1.375, -0.625)D, -0.875(-1.6, -0.625)D, -0.875(-1.625, -0.625)D, -1.25(-2.125, -0.75)D, respectively. The SE of non-myopic children aged 6～12 was +0.25(-0.125, +0.5)D, and the detection rate of insufficient hyperopia reserve was 75.51%. The SE of the non-myopic children aged 6～12 was +0.25(-0.125, +0.5)D, +0.25(0, +0.5)D, +0.125(-0.125, +0.5)D, +0.25(-0.125, +0.5)D, +0.125(-0.125, +0.5)D, +0.125(-0.125, +0.5)D, +0.25(-0.125, +0.625)D, respectively. The detection rates of myopia children aged 6～12 were 6.78%, 5.64%, 5.72%, 5.36%, 5.01%, 6.82%, 12.14%, respectively. The detection rates of insufficient hyperopia reserve children aged 6～12 were 91.67%, 92.04%, 92.91%, 83.85%, 68.89%, 54.01%, 26.71%, respectively. The detection rate of insufficient hyperopia reserve in non-myopic girls aged 9～12 years old was higher than that in boys(χ2=8.94, 19.99, 19.91 and 39.11, all P<0. 05); The detection rate of myopia in 10～12 year old girls was higher than that in boys(χ2=5.402, 8.493 and 36.9711, all P<0. 05).CONCLUSIONS: The prevalence rate of myopia among Uyghur children aged 6～12 years in Yecheng county of Xinjiang was 6.75%, while the detection rate of insufficient hyperopia reserve in non-myopic children reached up to 75.51%. It is predicted that there are a large number of children at high risk of myopia. Therefore, early monitoring of hyperopia reserve in children is vital for myopia prevention and control strategy.
