目的调查云龙区中小学生视力发育状况并针对其现状采取相应的干预措施。方法对云龙区1500名中小学生2009-2010年视力发育状况进行跟踪检测,采用E形对数视力表对1500名中小学生进行测量并记录检测结果。此外,将1500名学生分为干预组和对照组,对干预组采取眼部护理措施,2年后对两组结果进行比较。结果 2009年云龙区中小学生视力不良率为45.7%,而2010年检测的云龙区中小学生视力不良率为50.3%,相比之下,云龙区中小学生视力不良率呈明显上升趋势,而且女生视力不良率相比于男生视力不良率明显较高。此外,干预组视力发育状况相比于对照组具有明显优势,两组具有明显统计学差异(P<0.05)。结论由于中小学生视力不良率正在逐年上升,因此对其进行干预具有十分重要的意义。
