Abstract: Objective To identify the risk factors in relating to visual impairment. Methods As to the quantitative research, a total of 812 high-risk 18-month-old infants of Shanghai Minhang district were assessed vision screenings for grasping the current situation of visual impairment, meanwhile 149 without high-risk infants were also taken screenings as the control group.Data of vision screening of the respondents' from Nov.2011 till Dec.2012 had been used.

摘要： 目的 通过用Suresight 视力筛查仪对18月龄儿童进行屈光检查, 了解高危因素对儿童早期屈光度的影响。方法 2011年11月-2012年12月使用Suresight 视力筛查仪对在上海市闵行区18月龄的812名高危儿童进行屈光检查, 同龄非高危儿149人纳入对照组。结果 两组儿童球镜P₂₅~P₇₅参考值范围有差异, 双(多)胎儿的球镜屈光度比单胎儿接近正视, 两者之间差异有统计学意义。结论 高危因素对18月龄儿童的球镜屈光度有一定影响。
