通过彩色超声多普勒成像定量检测视网膜色素变性患者的血流动力学改变，用彩色超声多普勒诊断仪对１７例视网膜色素变性患者进行检测，测定双侧眼动脉、视网膜中央动脉、睫状后动脉的血流参数，对所测得数值用ｔ检验做统计学处理分析。结果：视网膜色素变性患者的血流改变与眼别无关，右、左眼对比无显著性差异（Ｐ＞０．０５），双侧眼动脉血流正常（Ｐ＞０．０５），双侧视网膜中央动脉及睫状后动脉血流速度较正常人显著减慢（Ｐ＜０．００１）。结论：彩色超声多普勒检查为视网膜色素变性患者的血流改变提供了量化指标
Quantitative detection of hemodynamic changes in patients with retinitis pigmentosa by color Doppler imaging, detection of 17 cases of retinitis pigmentosa by color Doppler diagnostic apparatus, detection of bilateral ophthalmic artery, central retinal artery, ciliary After the arteries of the blood flow parameters, the measured values were analyzed by t test statistical analysis. Results: The changes of blood flow in patients with retinitis pigmentosa had no correlation with eyes, there was no significant difference between right and left eyes (P> 0.05), normal bilateral blood flow (P> 0.05), bilateral retinal Central and posterior ciliary artery blood flow was significantly slower than normal (P <0.001). CONCLUSIONS: Color Doppler ultrasound provides a quantitative indicator of blood flow in patients with retinitis pigmentosa
