UNASSIGNED: A cross sectional study was carried out in children aged 6 to 14 years old from 50 schools in Poland. The presence of astigmatism was assessed by non-cycloplegic autorefraction, and defined as a cylinder equal or greater than 0.75 D. Children were classified as living in urban or rural areas according to the school location. Spectacle wear was defined as having spectacles at school.
UNASSIGNED: The study included 1041 children and 52.3% were girls (n = 544). The mean age was 8.62 ± 2.04 years. The prevalence of astigmatism was 7.3% (95% confidence interval [CI]: 5.8-9.1%). Only 21.7% of children with astigmatism wore spectacles at school. Astigmatism was diagnosed in 8.2% of boys (95% CI: 6.0-11.0%) and 6.4% of girls (95% CI: 4.5-8.8%; p = .13); cylindrical anisometropia was present in 19/76 (25.0%) of children with astigmatism (95% CI: 15.8%-36.3%). Against-the-rule astigmatism was the most common; it was observed in 48.7% of children with astigmatism, followed by with-the-rule astigmatism (44.7%) and oblique astigmatism (6.6%). The prevalence of astigmatism was not linearly correlated with age (r = 0.24; p = .53). Gender, age and place of living were not significantly associated with the presence of astigmatism.
UNASSIGNED: This study reports a low prevalence of astigmatism in Polish school children. However, the majority of children with astigmatism were uncorrected. Further longitudinal studies are warranted.
■对波兰50所学校的6至14岁儿童进行了横断面研究。散光的存在是通过非睫状肌麻痹自屈光来评估的,并定义为等于或大于0.75D的圆柱体。根据学校所在地,儿童被归类为生活在城市或农村地区。眼镜佩戴被定义为在学校戴眼镜。
■该研究包括1041名儿童,52.3%为女孩(n=544)。平均年龄为8.62±2.04岁。散光的患病率为7.3%(95%置信区间[CI]:5.8-9.1%)。只有21.7%的散光儿童在学校戴眼镜。8.2%的男孩(95%CI:6.0-11.0%)和6.4%的女孩(95%CI:4.5-8.8%;p=.13)被诊断为散光;19/76(25.0%)的儿童存在圆柱形屈光参差(95%CI:15.8%-36.3%)。反常散光是最常见的;在48.7%的散光儿童中观察到,其次是规则散光(44.7%)和斜散光(6.6%)。散光的患病率与年龄没有线性关系(r=0.24;p=0.53)。性别,年龄和居住地与散光的存在没有显着相关。
■本研究报告波兰学童散光患病率较低。然而,大多数散光儿童未矫正.需要进一步的纵向研究。
