The effect of the rate of the interpupillary distance (IPD) change with age on the near fusion free position was investigated in the present study.
Three hundred and fifty-two children aged from 2 to 16 years of age were tested. Interpupillary distance was estimated with a modified Viktorin's method and the near fusion free position was measured with a modified Maddox Wing.
The results reveal a significant difference in IPD growth rate between females and males and between children aged below and above 5 years. Most children below 5 years of age were orthophoric, but heterophoria became more common above 5 years of age.
The present study suggests that the oculomotor control system for convergence can compensate for age changes in IPD.
本研究调查了瞳孔间距（IPD）随年龄变化的速率对近融合无位的影响。
对352名年龄在2至16岁的儿童进行了测试。采用改良的维克托林方法估计瞳孔间距，并用改良的马多克斯翼测量近融合无位。
结果显示，女性与男性之间以及5岁以下和5岁以上儿童之间的IPD增长率存在显著差异。大多数5岁以下的儿童为正视眼，但5岁以上的儿童中隐斜视更为常见。
本研究表明，用于集合的眼动控制系统可以补偿IPD的年龄变化。
