目的：目的观察孔源性视网膜脱离（RRD）术后视盘和黄斑神经视网膜边缘组织血流的变化。研究方法：用海德堡视网膜血流计对53例53眼成功接受单侧RRD手术的患者的视盘和黄斑神经视网膜边缘的组织血流进行了测量。患者被分为三组：常规环扎巩膜外加压术（E组）、局部加压术（L组）和初次玻璃体切除术（V组）治疗RRD的患者。手术后6个月以上，在视网膜神经盘边缘的上级和下级边缘以及上级和下级黄斑区域的10度x 2.5度区域进行血流测量。比较3组患眼平均血流量（MBF）及患眼与健眼MBF比值（a/f比值）。还研究了几种临床因素对MBF的影响。结果：三组间MBF率及平均a/f值无显著性差异。多元回归分析显示，上级和低级椎间盘边缘的平均MBF仅与气体填充手术显著相关。结论：巩膜扣带术或玻璃体切除术治疗视网膜脱离术后6个月，眼微循环恢复正常。然而，使用气体填塞可能对神经视网膜盘边缘的循环产生亚临床不良影响。
Purpose: To investigate the tissue blood flow in the neuroretinal rim of the optic disk and macula after rhegmatogenous retinal detachment (RRD) surgery. Methods: Tissue blood flow in the neuroretinal rim of the optic disk and macula was measured with the Heidelberg retina flowmeter in 53 eyes of 53 patients who had undergone successful surgery for unilateral RRD. Patients were divided into three groups; those who had the RRD treated by conventional encircling scleral buckling (group E), by local buckling (group L), and by primary vitrectomy (group V). Blood flow measurements were made more than 6 months after surgery in a 10 degrees x 2.5 degrees area of the superior and inferior margins of the neuroretinal disk rim and of the superior and inferior macula area. The mean blood flow (MBF) and the ratio of the MBF in the affected eye to the healthy fellow eye (a/f ratio) were compared among the three groups. The influence of several clinical factors on the MBF was also investigated. Results: The MBF rate and mean a/f ratios of the MBF of the three groups were not significantly different. Multiple regression analysis revealed that the averaged MBF both at superior and inferior disk rims was significantly correlated with only the gas tamponade procedure. Conclusions: The ocular microcirculation is normal 6 months after scleral buckling or vitrectomy for RRD. However, the use of gas tamponade might have a subclinical adverse effect on the circulation in the neuroretinal disk rim.
