| 目的评价彩色多普勒显像(CDI)探查视网膜血管血流动力学是否可行。方法对80例(160只眼)无眼部疾患和既往眼部手术史,且除外能够影响血循环的高血压、贫血、心脏病、外周血管病、糖尿病的视网膜中央动脉(CRA)的峰值血流速度(PSA),舒张末血流速度(EDV)和视网膜中央静脉(CRV),最大血流速度(VV)进行了检测,男42例,女38例。平均年龄56.8岁。结果CDI探测CRA、CRV的显示率为100%.各测值结果处于一个较为稳定的范围。两个不同观察者之间各参数间比较,相关性良好,r=0.9249,无显着性差异,P>0.05.平均误差为5.17±2.8～8.9±6.23%.各血流参数在不同性别、眼别间无差异,P>0.05.结论CDI探查视网膜中央血管是一种简便、易行、准确的方法。在探查研究视网膜中央血管性疾病中,有极大的潜力。 |

| Purpose The possibility was evaluated,witch the color Doppler imaging (CDI) measure the hemodynamics of the retinal vessels.Methods The peak systolic velocity (PSV),end diastolic velocity (EDV) and vein velocity (VV) of the retinal vessels of 80 normal subjected,160 eyes,were studied.There were 42 men and 38 woman.Their average age was 56.8 years old.Results The results showed that the imaging rate of central retinal artery (CRA) and central retinal vein (CRV) was 100 per sent.The measurements were not significant difference between two investigators ( P >0.05 r =0.9249).The average error range was 5.17±2.8 to 8.9±6.23 per cent.No difference was found between male and female.Nether was left and right eve ( P >0.05).Conclusion CDI is a kind of simple、convenient、accurate method and has great potentiality in exploring and studing retinal central vessels disease. |
