摘　　要：目的探讨近距离眼动参数与初中生近视进展的关系,为开展学生近视防治工作提供科学参考。方法以28名近视初中生为研究对象,跟踪随访8～19个月,每3个月记录近距水平隐斜、AC/A、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正相关(r=0.416,0.495,0.463,P值均<0.05);将AC/A作为控制因素再行分析,调节滞后与年近视加深量,结果仍有正相关(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 explore the relationship between the nearwork oculomoter and the myopia progression in myopic adolescents, and to provide evidence for preventing myopia. Methods 28 myopic students were chosen as study subjects. They were followed up and checked for 8 to 19 months. During this period, oculomoter functions in form of series parameters were measured and analyzed. Results It showed that the response AC/A ratio, aecommodative hysteresis and accommodative amplitudes were positively correlated with the annual myopia progression; and the Pearson＇scorrelation coefficients （ 0.416, 0. 495 and 0. 463 respectively ） were significant at the 0.05 level. Moreover, in a scatter plot, it indicated that there was a linear relationship between the accommodative lag and the annual myopia progression;these variables were still positively correlated while being controlled for the effects of the response AC/A ratio （r=0.383,P〈0.05）. Conclusion High accommodative lag in the nearwork may be one of the reasons leading to myopia progression.
