目的：测定分析视网膜色素变性患者的血液粘度及其相互关系.方法：对50例视网膜色素变性患者和40例正常人对照，进行血液流变学检测及胆固醇、甘油三脂的检查.结果：视网膜色素变性患者的血液粘度、红细胞聚集指数及胆固醇、血脂明显高于正常人对照组.结论：视网膜色素变性病人具有高粘滞血症，能使血流速度变缓，再加上视网膜色素变性患者血管变细，故导致血液循环障碍，从而加重了视网膜，视神经功能的损害. OBJECTIVE: To determine and analyze the blood viscosity of patients with retinitis pigmentosa and its correlation.Methods: 50 cases of retinitis pigmentosa patients and 40 normal controls were performed hemorheological tests and cholesterol, triglyceride examination.Results: The retina The blood viscosity, erythrocyte aggregation index, cholesterol, and lipids in patients with pigmented degeneration were significantly higher than those in normal controls.Conclusion: Patients with retinitis pigmentosa have hyperviscosity and can slow down the blood flow, and in patients with retinitis pigmentosa Thinning blood vessels, it led to blood circulation disorders, thereby aggravating the retina, optic nerve damage.
