摘要
目的 分析视网膜静脉阻塞患者的血液流变学改变 ,探讨其发病机制 .方法 视网膜静脉阻塞患者 40 (男 2 0 ,女 2 0 )例 ,与相同例数的可以与之相匹配的正常对照组男、女各 2 0例进行血液流变学检查及统计学处理 ,并根据眼底荧光血管造影图像中有无毛细血管无灌注区及临床表现的严重程度分组 .结果 患者组明显高于对照组 (P <0 .0 5或 P<0 .0 1 )的项目有 :低切粘度、高切粘度、血浆粘度、全血还原比粘度、纤维蛋白原 .血液流变学各项指标增高程度与有无毛细血管无灌注无关 .结论 高血粘度与视网膜静脉阻塞的发生密切相关 ,但其程度与视网膜静脉阻塞的严重程度无关 .
AIM To find the pathogenic factor of retinal vein occlusion (RVO). METHODS Several items of hemorrheology in 40 cases (20 males and 20 females) of RVO were examined and compared with that of the control group including normal comparable 20 males and 20 females, the patients were divided into groups according to the clinical symptoms and clinical presentation of fluoresceint angiography. RESULTS Low shearing viscosity, high shearing viscosity, plasma viscosity, blood reduction viscosity, fibrinogen were higher in the RVO group than that of the control group ( P <0.05 or P <0.01). The results suggest that the indices of hemorrheology are not associatted with cappilary nonperfusion. CONCLUSION The high blood viscosity is closely related to the pathogenesis of RVO, but the vary degree is nothing with RVO.
