目的：通过多普勒血流检测了解老年人高血压病眼动脉和视网膜中央动脉血流动力学变化，并提供可靠数据。方法：采用美国Ａｃｕｓｏｎ－１２８型电脑声像仪测量７４例高血压患者眼动脉和视网膜中央动脉收缩期和舒张末期流速，阻力指数和搏动指数。结果：高血压患者的血流呈高阻力，低流速状态，外周血管阻力明显增加，舒张未期血流明显下降。结论：眼动脉和视网膜中央动脉的多普勒血流检测对老年人高血压病情预测，了解眼动脉硬化程度以及疗效观察有重要意义。
OBJECTIVE: To understand the hemodynamic changes of the ophthalmic and central retinal arteries in elderly hypertensive patients by Doppler flow test and provide reliable data. Methods: The systolic and diastolic velocity, resistance index and pulsatility index of the central arterial and central retinal arteries of 74 hypertensive patients were measured by the American Acuson-128 computer imager. Results: Hypertensive patients showed high resistance to blood flow, low flow rate, peripheral vascular resistance increased significantly, diastolic blood flow decreased significantly. Conclusion: Doppler blood flow measurement of the ophthalmic artery and central retinal artery can predict the severity of hypertension in the elderly and find out the degree of ophthalmic arteriosclerosis and the therapeutic effect.
