To observe the correlation between hemorrheology and arm-retinal filling time of fluorescein angiogaphy in patients with primary open-angle glaucoma.
The whole blood apparent viscosity in high (125 S-1), moderate (23 S-1) and low (1.2435 S-1) shear rates, plasma viscosity and hematocrit were measured in 50 cases (50 eyes) with primary open-angle glaucoma whose intraocular pressures were controlled. They also underwent fluorescein angiography. The duration from arm to retina arteria filling was named arm-retinal arteria filling time.
There were positive correlation between the whole blood apparent viscosity in high and moderate shear rates, hematocrit and arm-retinal arteria filling time (P < 0.05-0.005). The higher blood viscosity, the longer arm-retinal arteria filling time.
The blood viscosity in patients with primary open-angle glaucoma can affect the arm-retinal arteria filling time of fluorescein angiography. So, the increasing blood viscosity in patients with primary open-angle glaucoma can reduce the blood supply to the optic disc.
观察原发性开角型青光眼患者血液流变学与荧光素血管造影术的臂-视网膜充盈时间之间的相关性。
对50例（50只眼）眼压得到控制的原发性开角型青光眼患者测量其在高切变率（125 S-1）、中切变率（23 S-1）和低切变率（1.2435 S-1）下的全血表观黏度、血浆黏度和血细胞比容。他们还接受了荧光素血管造影术。从手臂至视网膜动脉充盈的持续时间被命名为臂-视网膜动脉充盈时间。
高切变率和中切变率下的全血表观黏度、血细胞比容与臂-视网膜动脉充盈时间之间存在正相关（P < 0.05 - 0.005）。血液黏度越高，臂-视网膜动脉充盈时间越长。
原发性开角型青光眼患者的血液黏度可影响荧光素血管造影术的臂-视网膜动脉充盈时间。因此，原发性开角型青光眼患者血液黏度的增加可减少对视盘的血液供应。
