title: Ocular pulse amplitude in myopia.
abstract: 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.
