Abstract

BACKGROUND

Color Doppler imaging allows for simultaneous two-dimensional anatomical imaging and Doppler evaluation of blood flow velocity.

METHODS

We examined 40 normal eyes (17 males and 23 females, aged 16 to 57 years) with this technique. The color Doppler unit used in this study had a 5.0-MHz PLF-503 ST phased-array scanning head. Each vessel examination was repeated 10 times during a single session.

RESULTS

The following peak flow velocities were found: central retinal artery, 12.5 +/- 2.4 cm/s; central retinal vein, 4.4 +/- 0.49 cm/s; posterior ciliary arteries, 14.4 +/- 2.6 cm/s; vorticose veins, 5.5 +/- 1.0 cm/s; ophthamic artery, 36.9 +/- 7.0 cm/s. Ophthalmic artery systolic and end-diastolic velocities declined as a function of age; however, these changes were not significant (systolic: r = -0.24; diastolic, r = -0.22).

CONCLUSION

This noninvasive technique allows quantitative assessment of blood flow velocity in these vessels.

摘要

背景

彩色多普勒成像可同时进行二维解剖成像和血流速度的多普勒评估。

方法

我们用该技术检查了40只正常眼睛（17名男性和23名女性，年龄16至57岁）。本研究中使用的彩色多普勒设备有一个5.0兆赫兹的PLF - 503 ST相控阵扫描头。每次检查时，每个血管检查重复10次。

结果

发现以下峰值血流速度：视网膜中央动脉，12.5±2.4厘米/秒；视网膜中央静脉，4.4±0.49厘米/秒；睫状后动脉，14.4±2.6厘米/秒；涡静脉，5.5±1.0厘米/秒；眼动脉，36.9±7.0厘米/秒。眼动脉收缩期和舒张末期速度随年龄增长而下降；然而，这些变化不显著（收缩期：r = -0.24；舒张期，r = -0.22）。
