方法：回顾性研究。7例硅油填充眼在随访时发现下方视网膜浅脱离。在硅油填充状态下行双通道27G玻璃体切除术。术中完成视网膜表面增殖膜剥离、视网膜下液抽吸，并在视网膜复位后行硅油下视网膜激光光凝术，根据患眼病情辅以巩膜外垫压或环扎。

结果：术后所有患眼视网膜均成功复位，术中未发生严重并发症。所有患眼术后眼表反应轻且视力迅速恢复至术前水平。1眼在术后20d出现视网膜再脱离，经传统的硅油取出联合视网膜复位术成功复位视网膜。

结论：双通道27G玻璃体切除术是一个治疗硅油填充眼早期视网膜再脱离的有效方法，可能具有更高的性价比。

METHODS: A retrospective study. Two-port 27-gauge pars plana vitrectomy was performed in 7 eyes with recurrent retinal detachment without remove of silicone oil. Proliferative membrane peeling, endolaser treatment, and drainage of subretinal fluid were performed. Scleral bulking was performed if necessary.

RESULTS: Sucessful retina re-attachment was accomplishied in all eyes. No visually significant intraoperative complication occurred. All eyes expericend quick recoveray of visual acuity and mild postoperative irritation. One eye developed a recurrent inferior retinal detchment in 20d after the surgery using non-remove technique, and recovered after conventional silicone oil removal and retinal reattachment surgery.

CONCLUSION: Two-port 27-gauge pars plana vitrectomy is an efficacious(and potentially cost-efficient)method to treat early stage recurrent retinal detachment in silicone oil dwelling eyes.
