目的 分析巩膜扣带术后视网膜脱离形成的原因和玻璃体手术治疗方法。方法 回顾 4 6例 (46只眼 )孔源性视网膜脱离患者的临床资料及其手术治疗方法。结果 巩膜扣带术后 2 4只眼出现新孔 ,其中 7只眼为黄斑部裂孔 ;18只眼 PVR发展 C级以上 ;5只眼原裂孔未封闭 ;5只眼合并有脉络膜脱离 ;这些因素导致 35只眼视网膜下液持续不吸收。 38只眼玻璃体手术后视网膜复位 ,占 82 .6 % ;多次手术后最终手术成功 4 5只眼 ,成功率为97.8%。结论 巩膜扣带术后失败原因主要为新孔的发生、PVR发展和视网膜下液不吸收 ;再次玻璃体手术时 ,掌握手术时机 ,对症处理 ,是提高手术成功率的关键
Objective To analyze the causes of retinal detachment after scleral buckling and the surgical treatment of vitreous. Methods The clinical data and surgical treatment of rhegmatogenous retinal detachment in 46 cases (46 eyes) were retrospectively reviewed. Results There were new holes in 24 eyes after scleral buckling. Among them, 7 eyes had macular holes, 18 eyes had PVR developed above grade C, 5 eyes had unobstructed protuberances and 5 eyes had choroidal detachment. These factors Resulting in 35 non-subretinal fluid continued to absorb. Retinal reattachment was found in 38 eyes after vitreous surgery, accounting for 82.6% of the total; 40 eyes were successfully operated after multiple surgeries with a success rate of 97.8%. Conclusions The main reasons for the failure of scleral buckling surgery are the occurrence of new holes, the development of PVR and the non-absorption of subretinal fluid. To grasp the timing of surgery and symptomatic treatment during vitreous surgery is the key to improve the success rate of surgery
