Abstract： 目的探讨视网膜脱离(retinal detachment,RD)手术对患者视网膜和视乳头血流的影响.方法应用共焦扫描激光多普勒视网膜血流分析仪( heidelberg retina flowmeter,HRF) 检测62例(62只眼)单眼孔源性RD术后患者的视网膜和视乳头血流参数.其中34只眼采用玻璃体视网膜 (vitreoretinal,VR)手术,28只眼采用常规巩膜扣带(scleral bucking,SB)术,手术方式包括巩膜环扎术、巩膜外冷冻术、晶状体或玻璃体切除术、眼内激光光凝术,术中应用全氟萘烷液体、长效气体及硅油填充等.结果 RD组与对照组比较,眼底血流量、血流速及红细胞移动速率均降低,颞侧视乳头盘沿及鼻侧视乳头盘沿的红细胞移动速率差异均有显著意义(P<0.05);视乳头大血管血流量、血流速及红细胞移动速率,颞侧、鼻侧视乳头盘沿的血流量及血流速,颞侧、鼻侧视乳头旁视网膜血流量相比较,差异均有非常显著意义(P<0.01).VR术组与SB术组比较,其血流量、血流速及红细胞移动速率均明显降低;颞侧、鼻侧视乳头盘沿,鼻侧视乳头旁视网膜的红细胞移动速率,颞侧视乳头旁视网膜的血流速比较,差异均有显著意义(P<0.05).硅油填充组与未填充组比较,其眼底血流量、血流速及红细胞移动速率均降低;其中鼻侧视乳头盘沿及鼻侧视乳头旁视网膜血流量比较,差异均有显著意义(P<0.05);颞侧视乳头盘沿血流量及红细胞移动速率、颞侧视乳头旁视网膜的血流量比较,差异均有非常显著意义(P<0.01).结论 VR术组与SB术组患者的视网膜和视乳头血流量、血流速、红细胞移动速率均受RD手术的影响,VR术组较SB术组明显,术中硅油填充亦影响患者的眼底血流量及红细胞移动速率.
