简介：目的通过对我区学校视力监测点监测结果进行分析,了解儿童、青少年视力不良的发展动态.方法对我区2000～2001年二所中学二所小学二所幼儿园视力监测结果进行统计分析.结果(1)二所中学二所小学二所幼儿园学生视力不良以屈光不正为主.(2)屈光分析表明近视屈光不正发病率中学最高,占91.85%;其次是小学,占53.47%,但以轻度近视为主;幼儿园学生以远视屈光不正发病率为高,占74.52%,以轻度远视为主.(3)随着年龄的增长,学习任务的增加,视力不良、近视屈光的发生率增加.结论在中小学、幼儿园中进行视力监测和屈光状态分析可早期发现屈光不正和弱视,及时防治,对控制小学生视力不良有重要意义,为了今后更好地做好视力不良的防治工作还需教育、预防、临床等部门密切配合和政府部门政策性的支持.

简介：目的比较24h眼压监测中夜间即刻坐位眼压值和坐起休息10min后测得的眼压值，探讨夜间眼压的不同测量方法对青光眼24h眼压昼夜波动的影响。方法对已确诊且未用药、未做过手术的48例正常眼压性青光眼及17例原发性开角型青光眼患者进行24h眼压监测，每2h1次，其中测量夜间0：00、2：00、4．00眼压时，逐个唤起患者后立即测，后嘱患者坐起休息10min再测，采用SPSS软件以配对t检验分析比较测量结果。结果夜间即刻坐位眼压值和坐起休息10rain后测得的眼压值差异有统计学意义（P〈0．001），正常眼压性青光眼与原发性开角型青光眼间眼压差值差异有统计学意义（P〈0．05）。结论即刻坐位眼压值能更准确反映夜间眼压，对24h眼压测量及青光眼诊断及治疗更有价值，值得临床应用。
