老年人高血压病眼动脉和视网膜中央动脉的彩色超声多普勒血流检测

Blood flow detemination of the ophthalmic and central retina arteries with color Doppler echography in senile hypertensive patients

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:The blood flow of ophthalmic and central retinal arteries was measured by color Doppler ultrasound to understand the state of blood circulation and to provide reasonable data in 74 senile hypentensives. Methods:The blood flow velocity of the systolic and diastolic phase, the resistance and pulse indexes of ophthalmic and central retinal artery were measured with Acuson 128 computer sound spectrum. Results:The blood flow velocity、the peripheral vascular resistance and the blood flow of the end diastolic phase were distinctly decreased as compared with the controls.Conclusion:Our data indicate that it may be very useful in understanding the state and the extent of ophthalmic arteriosclerosis and obstruction in senile hypertensive patients by measuring the blood flow of the ophthalmic and central retinal artery with color Doppler ultrasound.
