[摘要] 目的:观察儿童青少年近视眼戴普通凹透镜、戴渐进多焦镜和不戴矫正镜对屈光变化的影响。方法:2007年3月~2008年12月门诊就诊的近视儿童152例(304只眼),近视度数0.5~2.0 DS,排除屈光不正以外的其他眼病,用0.5%托吡卡胺眼液扩瞳验光查出屈光度数,次日复验。随机分为三组:戴普通凹镜组53例(106只眼),戴矫正视力=1.0的普通凹透镜;戴渐进多焦镜组51例(102只眼),戴下加+1.5D的渐近多焦镜片;不戴矫正镜组48例(96只眼)。6个月和12个月以后复诊,扩瞳验光复查屈光度。结果:3次屈光检查结果表明各组间比较均无显著性差异(P>0.05)。结论:戴凹透镜或渐进多焦镜不能减缓儿童青少年近视的发展。

[Abstract] Objective: To observe the influence of general concave lens, progressive addition lenses and no corrective lens on the refractive change of children and adolescents. Methods: 152 cases of out-patients myopic children (304 eyes) from March 2007 to December 2008 whose myopia extend 0.50 to 2.0 DS, excluding other eye diseases except refractive errors, was treated with 0.5% tropicamide mydriatic to detect refractive optometry. Next day the cases were randomly divided into 3 groups: 53 cases(106 eyes) who wear normal concave lens of 1.0 corrected visual acuity; 51 cases (102 eyes) who wear progressive multifocal lenses of +1.5D addition; 48 cases (96 eyes) who do not wear the correct lens. And reviewed the refractive optometry 6 months and 12 months after the referral. Results: 3 times refraction results showed that there was no significant difference between groups (all P>0.05). Conclusion: The concave lens or progressive multifocal lens could not slow down the development of myopia in children and adolescents.

为观察儿童青少年近视眼戴普通凹透镜、戴渐进多焦镜和不戴矫正镜对屈光变化的影响。笔者于2007年3月~2008年12月对门诊就诊的152例近视儿童进行了1年的临床观察。现将结果报道如下:
1 资料与方法
1.1 一般资料
收集2007年3月~2008年12月门诊就诊的近视儿童152例(304只眼),其中,男88例,女64例;年龄7~15岁,平均12.6岁;近视度数0.5~2.0 DS,散光度数<1.0 DC,以等效球镜值计算,屈光参差<1.00D。全部儿童均经眼位、裂隙灯、眼底等检查,排除屈光不正以外的其他眼病。
1.2 方法
采用0.5%托吡卡胺眼液点眼每10~15分钟1次,共3~4次,用电脑验光仪和带状光检影镜查出屈光度数,次日复验。将其随机分为3组:戴普通凹镜组53例(106只眼),戴矫正视力=1.0的普通凹透镜;戴渐进多焦镜组51例(102只眼),戴下加+1.5D的渐近多焦镜片;不戴矫正镜组48例(96只眼)。所有儿童6个月和12个月复诊,重新扩瞳、验光、复查屈光度。
1.3 统计学分析
3次屈光检查结果采用SPSS 16.00统计软件运用方差分析。
2 结果
第1、6、12个月3次屈光检查结果各组间差异比较均无显著性意义(均P>0.05),见表1 ......
