目的:探讨玻璃体切除手术治疗视网膜分支静脉阻塞引起的玻璃体积血的临床效果。方法:回顾分析28例28眼视网膜分支静脉阻塞引起的玻璃体积血患者进行闭合式玻璃体切除,联合增殖膜剥离、眼内激光光凝及玻璃体腔长效气体、硅油或灌注液填充手术的临床疗效。结果:该28例患者术中均可见视网膜分支静脉阻塞闭锁呈白线状。视网膜静脉阻塞颞上方20例,颞下方8例。合并视盘新生血管2例,18例阻塞区可见视网膜新生血管及交通支。并发视网膜脱离7例,患者术前及术后视力比较有统计学差异(P<0.05)。结论:玻璃体切除是视网膜分支阻塞的有效手术方法,术中应谨慎去除阻塞区增殖病灶,光凝视网膜无灌注区,术后注意观察阻塞部位的视网膜复位及增殖情况。

AIM:To study the clinical curative effect of vitrectomy for vitreous hemorrhage in branch retinal vein occlusion.METHODS:Twenty-eight cases 28 eyes of vitreous hemorrhage caused by branch retinal vein occlusion were taken into investigation.All the patients accepted routine three-way joint vitrectomy combined with membrane peeling,diathermy,retinal photocoagulation and silicon or gas or fluid tamponade.RESULTS:The branch retinal vein occlusion seemed to be vascular sheathing in 28 eyes.The occlusion areas were supertemporal quadrant in 20 eyes,infratemporal quadrant in 8 eyes.2 eyes had disc neovascularization,18 eyes had retinal neovascularization in the areas of retinal vein occlusion.Retinal detachment was found in 7 eyes.The postoperative visual acuity was better than that of preoperative.CONCLUSION:Vitrectomy is an effective way for branch retinal vein occlusion with vitreous hemorrhage.The proliferation should be carefully removed.
