Comparison of the haemodynamic measurements obtained by colour Doppler imaging and other methods of ocular blood flow measurements was desired.
The blood velocity findings from colour Doppler imaging of patients with central retinal vein occlusion were compared to the results of fluorescein video-angiography, continuous tonography and ophthalmodynamometry.
Patients with low or undetectable blood velocities in the central retinal vein had longer retinal dye transit times on fluorescein video-angiography. Tonography showed a positive correlation with the velocities in the ophthalmic artery, but ophthalmodynamometry showed a negative correlation with these velocities.
The relationships between the blood velocities in orbital vessels and other blood flow measurements emphasise that there is a complex interaction of the blood flow parameters. Care must therefore be taken when interpreting the results of studies.
需要比较彩色多普勒成像所获得的血流动力学测量结果与其他眼部血流测量方法的结果。
将视网膜中央静脉阻塞患者彩色多普勒成像的血流速度结果与荧光素视频血管造影、连续眼压描记法和眼血流动力学测量的结果进行比较。
视网膜中央静脉血流速度低或检测不到的患者，在荧光素视频血管造影上视网膜染料通过时间更长。眼压描记法显示与眼动脉速度呈正相关，但眼血流动力学测量与这些速度呈负相关。
眼眶血管血流速度与其他血流测量之间的关系强调了血流参数存在复杂的相互作用。因此，在解释研究结果时必须谨慎。
