目的：彩色多普勒超声检查测定远视患者眼眶血管血流动力学改变，与非远视眼进行对比。
方法：18例患者(36眼)被纳入该项研究中，其中20眼为远视眼，16眼正常。彩色多普勒超声检查所有眼的眼动脉，视网膜中央动脉，以及睫状后动脉血流情况。
结果：两组间唯一差别为远视眼眼动脉显著降低的最大收缩速度(32.70±11.60 vs 55.01±11.68， P=0.001)及舒张末期血流速度(6.83±1.91 vs 13.99±4.15， P=0.001)。
结论：该项研究表明弱视眼较正常眼球后血流速度有所减慢。

[Abstract]
AIM: To assess the hemodynamic changes in the extraocular orbital vessels of amblyopic patients in comparison with non-amblyopic fellow eyes, using color Doppler ultrasonography(CDU).
METHODS: Thirty-six eyes of 18 pediatric patients were included in the study(20 amblyopic, 16 normal). All eyes underwent color Doppler ultrasonography examination of ophthalmic artery, central retinal artery, and posterior ciliary artery.
RESULTS: The only differences between the two groups with regard to color Doppler ultrasonography parameters was the significantly lower peak systolic velocity(32.70±11.60 vs 55.01±11.68, P=0.001)and end-diastolic velocity(6.83±1.91 vs 13.99±4.15, P=0.001)for ophthalmic artery in amblyopic eyes.
CONCLUSION: Our study showed amblyopic eyes may present a decrease in retrobulbar blood flow velocity.
