因为1998研究结果提示自动验光结果与视网膜检影一致性良好，因此2000年纵向研究中取消了睫状肌麻痹后的视网膜检影。

The spherical equivalence of cycloplegic auto-refraction equal or less than -0.5D in either eye is defined as myopia and that equal or higher than +2D is defined as hyperopia.

分析了学龄期儿童的纵向屈光改变情况、近视眼的发病率及其危险因素、儿童视力现状以及一些常见眼病的患病率情况。

Methods Sixty students(120 eyes)with myopia(within-2.50D)were selected.visival acuity,cycloplegic refraction,keratometer,ocular axis,stereoscopic vision,and phoria strabismus were observed before and after 1～1.5 years wearing Anti-myopia Glasses.

近视的发生和发展与环境的影响密切相关[2]，特别在青少年时期，过分的和不适当的阅读、书写、观看电脑屏幕及其他近工作，是促成近视的重要因素[3]。

METHODS: Refractive error (cycloplegic auto-refraction with subjective refinement), central corneal thickness and axial length, intraocular pressure, and corneal hysteresis (Reichert Ocular Response Analyzer) were measured on a rural school-based cohort of children.

在以一个农村地区学校为基础的队列中，对这些儿童进行屈光不正（睫状肌麻痹性自动验光和主观优化）、中央角膜厚度、眼轴长度、眼内压和角膜滞后（Reichert眼部反应分析仪）等指标的检测。
