We studied the ocular pulse amplitude of myopic patients by using Alcon Pneumotonography. One hundred and eighty-eight cases (376 eyes) were enrolled in this study. The results revealed that the higher the myopia the lower the ocular pulse amplitude. The pulse amplitude has high correlation with refractive error and axial length, but poor correlation with scleral rigidity, intraocular pressure and corneal curvature. As the ocular pulse amplitude is generated by the choroidal blood flow, these results may reflect circulatory disturbance in the development of myopia.
我们使用爱尔康气动眼压描记法研究了近视患者的眼脉冲幅度。本研究纳入了188例（376只眼）。结果显示，近视度数越高，眼脉冲幅度越低。脉冲幅度与屈光不正和眼轴长度高度相关，但与巩膜硬度、眼压和角膜曲率相关性较差。由于眼脉冲幅度由脉络膜血流产生，这些结果可能反映了近视发展过程中的循环障碍。
