Ultrasonographic biometric measurements (axial length of the globe, lens thickness and anterior chamber depth) were taken in 89 eyes of patients with primary angle-closure glaucoma (ACG). Analysis of the mean values showed an apparently abnormal pattern of growth of the lens, its thickness increasing at an accelerated rate between the fourth and sixth decades, then not increasing for about a decade, and finally increasing again but at a slower pace. The anterior chamber depth, however, appeared to continue decreasing at a constant rate. This suggests that forward movement of the lens, probably secondary to loosening of the zonules, is also a factor in the shallowing of the anterior chamber. The frequency of acute attacks of ACG peaked twice, first in the presbyopic years, at ages 53 to 58, and then in the senile years, at ages 63 to 70; no attacks occurred during the decade in which the lens seemed not to be growing.
对89例原发性闭角型青光眼（ACG）患者的眼睛进行了超声生物测量（眼球轴长、晶状体厚度和前房深度）。平均值分析显示，晶状体生长模式明显异常，其厚度在40至60岁之间加速增加，随后约十年不增加，最后再次增加，但速度较慢。然而，前房深度似乎以恒定速率持续减小。这表明晶状体向前移动，可能继发于悬韧带松弛，也是前房变浅的一个因素。ACG急性发作的频率出现两次高峰，第一次在老花眼年龄段，即53至58岁，第二次在老年年龄段，即63至70岁；在晶状体似乎不生长的十年期间未发生发作。
