注气视网膜固定术治疗孔源性视网膜脱离临床观察

Clinical observation on pneumatic retinopexy of rhegmatogenous retinal detachment

目的:为更有效地开展注气视网膜固定术进一步总结经验。方法:回顾性分析5a来广东省人民医院眼科行注气视网膜固定术的患者手术效果。结果:共进行32例注气视网膜固定术,20例一次手术成功(62.5%)。未成功患者为术后增殖性玻璃体视网膜病变(proliferati vevitreoretinopathy,PVR)形成致原裂孔张开或新裂孔形成以及黄斑孔未作光凝。术中未发生视网膜晶状体损伤。结论:注气视网膜固定术对上方象限小裂孔引起的视网膜脱离效果良好,尤其萎缩孔效果最好,该方法简单,值得尝试。

AIM：To sum up the experience for more effectively carrying out pneumatic retinopexy. METHODS：The cases which had taken pneumatic retinopexy were analyzed retrospectively in Guangdong provincial people＇s hospital in five years. RESULTS：A total of 32 cases had taken pneumatic retinopexy, 20 cases （62.5%） of them had a successful retinal reattachment with one time surgery. The reopening of original hole for proliferative vitreoretinopathy（PVR） or new hole and macular hole without photocoagulation accounted for the causes of failure. No retinal or lens injury were observed in operation. CONCLUSION：Pneumatic retinopexy has favorable effect for small hole which locates in above quadrant, especially for shrinking hole. The method in this paper is simple and worth trying.
