背景目前关于中国大陆近视患病率的种族差异的信息有限，特别是在农村或半农村地区。我们研究了屈光不正的患病率，视力障碍和眼镜覆盖率在不同种族的学童在吐鲁番，新疆provincy.MethodsA社区眼科保健服务提供了五所学校。评估单眼远视力、近视力和眼球排列情况。对存在视力障碍（远视力低于0.3 logMAR; Snellen 6/12或20/40）或双眼视觉异常的参与者进行视网膜镜检查和睫状肌麻痹主观验光。在眼科检查之前进行的问卷被用来收集关于个人生活方式和父母近视的信息。ResultsA总共有646/690（94%）的受试者年龄在4到19岁（11.92.6;平均值+/- S.D.）。完成了眼部检查。382名（59%）参与者是维吾尔族，其次是汉族，176名（27%）和回族，74名（12%）。维吾尔族、汉族和回族学生的平均年龄分别为12.3 ± 2.7岁、11.4 ± 2.6岁和11.4 ± 2.3岁，其中维吾尔族学生的年龄显著大于汉族和回族学生（F-（3，F-631）=5.58，P <0.01）。
BackgroundThere is currently limited information about ethnic differences in myopia prevalence within mainland China, especially in rural or semi-rural areas. We examined the prevalence of refractive errors, visual impairment and spectacle coverage in school children of varying ethnicity in Turpan, Xinjiang province.MethodsA community eye care service was provided for five schools. Presenting monocular distance and near visual acuity (VA), and ocular alignment were assessed. Retinoscopy and cycloplegic subjective refraction were performed for participants with presenting visual impairment (distance VA worse than 0.3 logMAR; Snellen 6/12 or 20/40) or abnormal binocular vision. Questionnaires administered prior to the eye examinations were used to collect information regarding personal lifestyle and parental myopia.ResultsA total of 646 out of 690 (94%) subjects aged four to 19years (11.92.6; mean +/- S.D.) completed the eye examination. Three hundred and eighty-two (59%) of participants were of Uyghur ethnicity, followed by Han, 176 (27%) and Hui, 74 (12%). The mean age of Uyghur, Han and Hui students was 12.3 +/- 2.7, 11.4 +/- 2.6 and 11.4 +/- 2.3years respectively, in which the Uyghur students were significantly older than the Han and Hui students (F-(3,F-631)=5.58 p
