摘　　要：目的探讨近距离眼动参数与青少年近视进展的关系。方法以28名近视青少年为研究对象跟踪随访8～19个月，每3个月记录近距水平隐斜、AC／A、负相对调节、正相对调节、调节滞后、调节幅度等近距离眼动参数，检测双眼平均等效球镜值，根据首次与末次双眼平均等效球镜值计算年近视进展量作为近视加深速度，分析各近距离眼动参数与年近视进展量之间的相关性。结果AC／A、调节滞后及调节幅度与年近视进展量均呈负相关（相关系数r分别为-0．416，-0．495及-0．463，P均小于0．05）；考虑到AC／A与调节滞后相互关联，将AC／A作为控制因素再行分析，调节滞后与年近视加深量仍有相关性（r-=0．383，P〈0．05）。结论近距离工作时高调节滞后可能是导致近视进展的原因之一。Objective To investigate the relationship between the nearwork oculomoter functions and the myopia progression in myopia juveniles. Methods 28 students were followed up and visited for 8 to 19 months and their oculomoter functions such as heterophoria,the response AC/A ratio,negative relative accommodation,positive relative accommodation,accommodative lag and accommodative amplitudes were measured and analyzed. Results The response AC/A ratio, accommodative hysteresis and accommodative amplitudes were correlated with the annual myopia progression; and the Pearson＇s correlation coefficients （-0.416,-0.495 and -0.463 respectively） were significant at the 0.05 level. A scatterplot indicated that there was a linear relationship between the accommodative lag and the annual myopia progression;these variables were still negatively correlated while controlling for the effects of the response AC/A ratio （r =-0.383, P 〈0.05）. Conclusion High accommodative lag in the nearwork maybe one of the reasons lead to myopia progression.
