准分子激光原位角膜磨镶术患者视网膜微循环血流的研究

Retinal microcirculation blood flow in myopic patients for LASIK

目的 本研究主要观察 L ASIK中负压吸引对视网膜微循环血流的影响。方法 采用海德堡视网膜血流仪分别对实施 L ASIK手术的低度、中度和高度的近视患者共 38例6 2眼进行检测 ,测量视盘大血管、视盘颞侧盘沿、视盘鼻侧盘沿、颞侧视盘旁视网膜、鼻侧视盘旁视网膜和巩膜筛板的血流 ,并对其手术前后的血流量、血流速和红细胞移动速率进行统计分析。结果 L ASIK手术前后 ,视盘大血管、视盘颞侧盘沿、视盘鼻侧盘沿、颞侧视盘旁视网膜、鼻侧视盘旁视网膜和筛板的血流量、血流速和红细胞移动速率均无显著性差异。结论 L

Objective To investigate the effects of suction on the retinal microcirculation blood flow in myopic patients for LASIK. Methods Heidelberg retina flowmetry (HRF) was performed on 38 patients(62 eyes) , who were entered into the three groups( the low, the middle and the high myopia). Volume, flow and velocity were analyzed in papillary vascular, temporal rim, nasal rim, temporal juxtapapillary retina, nasal juxtapapillary retina and scleral cribrum before and after LASIK. Results Of volume, flow, and velocity,there were no significant differences in papillary vascular, temporal rim, nasal rim, temporal juxtapapillary retina, and nasal juxtapapillary retina before and after LASIK in each group. Conclusion It is postulated that the suction can't significantly affect the retinal microcirculation blood flow in myopic patients for LASIK
