开角型青光眼血液流变学与眼底荧光血管造影相关关系的研究

观察原发性开角型青光眼患者血液粘度与眼底荧光血管造影充盈时间之间的关系。测量了眼压已控制的原发性开角型青光眼５０例５０只眼高（１２５Ｓ＾－１）、中（２３Ｓ＾－１）和低（１．２４３５Ｓ＾－１）切变率下全血表观粘度，测量了血浆粘度和红细胞压积，进行了眼底荧光血管造影。将四枝视网膜中央动脉完全充盈的时间定为臂一视网膜中央动脉充盈时间。高、中切变率下全血表观粘度、红细胞压积均与臂－－视网膜中央动脉充盈时间

The Study of Correlation between Hemorrheology and Fluorescein Angiography in Open-angle Glaucoma

Purpose: To observe the correlation between hemorrheology and arm - retinal filling time of fluorescein angiogaphy in patients with primary open-angle glaucoma.Methods: The whole blood apparent viscosity in high (125S-1 ) , moderate (23S-1) and low (1. 2435S-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.Results: 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.Conclusion: 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 pmary open-angle glaucoma can reduce the blood supply to the optic disc. Eye Science 1995; 11: 73- 75.
