了解北京市3～6岁异常视力儿童屈光状态.方法 采用分层随机整群抽样的方法,对北京市3～6岁儿童(5 586名)的视功能进行了调查,本文仅就单眼裸眼视力<0.9者(370例、740只眼)的屈光状态及伴斜视、弱视患儿的屈光状态进行了分析.结果 屈光不正总患病率为6.53%,远视、混合散光、近视患病率依次为:4.76%、1.56%、0.30%(P<0.01);轻、中、重度屈光不正患病率依次为:3.68%、2.05%、0.90%(P<0.01);屈光不正分布有地区差异(城镇高于农村,P<0.01)和年龄特点(4岁组患病率高于其他年龄组,P<0.01);斜视患病率为0.80%,弱视患病率为2.22%,弱视首次检出率84.85%.远视性屈光不正是导致斜、弱视的主要病因.
To understand the refractive status of children aged 3 ~ 6 years old with abnormal vision in Beijing.Methods The stratified random cluster sampling method was used to investigate the visual function of 5 586 children (5 586) in Beijing. Visual acuity <0.9 (370 cases, 740 eyes) refractive status and with strabismus, amblyopia in children with refractive status were analyzed.Results The total prevalence of refractive error was 6.53%, hyperopia, mixed astigmatism, myopia The morbidity rates were 4.76%, 1.56% and 0.30% respectively (P <0.01). The prevalence of mild, moderate and severe refractive errors were 3.68%, 2.05% and 0.90%, respectively There were regional differences (urban higher than rural, P <0.01) and age characteristics (prevalence in 4-year-old group was higher than other age groups, P <0.01); strabismus prevalence was 0.80%, amblyopia prevalence was 2.22% , The first detection rate of amblyopia was 84.85% .Myopic refractive error is the leading cause of oblique, amblyopia.
