老年盘变患者的血液流变学改变

Abnormalities in blood rheology in the patients with age-related macular degeneration

目的：观察老年盘变患者的血液流变学改变。 方法采用ＬＢＹ－Ｎ６型血液粘度计检测２０例老年盘变患者和１０例正常人的３项主要血液流变学指标。 结果全血低切粘度和血浆高切粘度在研究组与对照组之间及研究组的不同年龄组之间均存在显著性差异，干、湿性老年盘变患者之间的３项指标均无显著性差异。 结论基于血液流变学对微循环及组织营养代谢的影响及老年盘变的病理特点，推测血液流变学改变可能是诱发老年盘变的因素之一。

Objective: To investigate the changes in blood rheology in the patients with age-related macular degeneration (AMD). Methods The main three blood rheological indicators were examined with LBY - N6 viscometer in the 20 patients with AMD and 10 healthy individuls. Results The results of X2 test revealed that there were significances in the primary blood rheological indicators between two groups and different age groups,but no significances between the patients with dry and wet AMD. Conclusion Seen logically, the abnormalities in blood rheology may be one of the factors which induce AMD.
