摘　　要：目的 :研究高度近视眼的微循环血液动力学变化。方法 :应用彩色多普勒对 3 8只高度近视眼和 40只正常眼的眼动脉、睫状后短动脉、视网膜中央动脉的收缩期最大流速、阻力指数结果进行对比分析。结果 :高度近视眼组和正常组的血流参数比较 ,睫状后短动脉和视网膜中央动脉的收缩期最大流速和阻力指数均低于正常组有显著差异 ( P<0 .0 1)。眼动脉血流参数无明显差异 ( P>0 .0 5 )。结论 :高度近视眼的睫状后短动脉、视网膜中央动脉的血流参数均明显降低 ,彩色多普勒有可能应用于眼的微循环的血液动力学的病理改变形成机制的研究。Objective: To study the changes of microcirculatory hemodynamics of highmyopes. Methods: With the color Doppler, systolic peak velocity(SPV) and resistance index(RI) of ophthalmic artery(OA), short posterior ciliary artery(SPCA) and central retinal artery(OA) of 38 eyes with highmyopes were analyzed and compared with 40 normal eyes. Results: The systolic and resistance index of short posterior ciliary artery and central retinal artery in highmyopes group were lower than these in normal group( P < 0.01 ), to the ophthalmic artery( P > 0.05 ). Conclusion: The Doppler flow indexes of the short posterior ciliary artery and central retinal artery were obviously low in highmyopes. These will be helpful to study the changes of microcirculatory hemodynamics and its pathological mechanism of higmyopes.
