UNASSIGNED: A cross-sectional study and random sampling survey were conducted. Between January and November 2021, 21,415 students aged 5 to 13 years from 14 primary schools in Langzhong City underwent non-cycloplegic refractive testing using autorefraction. The data on myopia were analyzed using SPSS (Statistical Package for the Social Sciences) version 23.0.
UNASSIGNED: The inclusion criterion was set at an absolute astigmatism value of ≥0.50D. Among the 21,415 children studied, 61.70% were found to have astigmatism. The prevalence of astigmatism varied significantly across different grades (χ2=501.414, P<0.001). The predominant types of astigmatism were mild astigmatism (0.50-1.00D) and with-the-rule astigmatism. Mixed astigmatism was primarily observed in children in grades 1 and 2, while compound myopic astigmatism was more common in children in grades 3 to 6. These differences were statistically significant. As the degree of astigmatism increased, the proportions of against-the-rule astigmatism, oblique astigmatism, compound myopic astigmatism, and simple hyperopic astigmatism decreased, whereas the proportions of with-the-rule astigmatism, mixed astigmatism, and compound hyperopic astigmatism increased.
UNASSIGNED: The prevalence of astigmatism among school-age children aged 5 to 13 years in northeast Sichuan is notably high, with compound myopic astigmatism and with-the-rule astigmatism being the most common types. Regular refractive examinations are crucial for the early detection and management of astigmatism.
■进行了横断面研究和随机抽样调查。在2021年1月至11月期间,来自lang中市14所小学的21,415名5至13岁的学生使用自动屈光进行了非睫状肌麻痹屈光测试。使用SPSS(社会科学统计软件包)23.0版分析近视数据。
■纳入标准设置为绝对散光值≥0.50D。在研究的21,415名儿童中,61.70%的人发现有散光。不同等级的散光患病率差异显著(χ2=501.414,P<0.001)。散光的主要类型是轻度散光(0.50-1.00D)和规则散光。混合散光主要在1级和2级儿童中观察到,而复合近视散光在3至6级儿童中更为常见。这些差异具有统计学意义。随着散光程度的增加,违规散光的比例,斜散光,复合性近视散光,单纯远视散光减少,而正常散光的比例,混合散光,复合远视散光增加。
■川东北5~13岁学龄儿童散光患病率明显较高,复合近视散光和规则散光是最常见的类型。定期的屈光检查对于早期发现和治疗散光至关重要。
