PURPOSE
The purpose of the study is to determine the success rate of pneumatic retinopexy (PR) after failed scleral buckling and to elucidate the predictors for anatomic failure by multiple logistic regression analysis.
METHODS
Thirty-six eyes with recurrent retinal detachment after failed scleral buckling underwent PR. Intraocular tamponade was attained with SF6 (20 eyes), C3F8 (13 eyes), and air (3 eyes). Median follow-up was 14 months.
RESULTS
Retinal reattachment was obtained in 69.4%. Multivariate analysis identified two risk factors for failure: location of retinal break either on the posterior slope or posterior to buckle (P = 0.01) and extent of retinal detachment greater than two quadrants (P = 0.02).
CONCLUSIONS
Pneumatic retinopexy is an effective alternative to revision surgical operations if the leaking retinal break is located on the buckle.
目的
本研究旨在确定巩膜扣带术失败后气体性视网膜固定术（PR）的成功率，并通过多因素逻辑回归分析阐明解剖学失败的预测因素。
方法
36只巩膜扣带术失败后发生复发性视网膜脱离的眼睛接受了PR。使用SF6（20只眼）、C3F8（13只眼）和空气（3只眼）进行眼内填充。中位随访时间为14个月。
结果
视网膜复位率为69.4%。多因素分析确定了两个失败的危险因素：视网膜裂孔位于后坡或扣带后方（P = 0.01）以及视网膜脱离范围大于两个象限（P = 0.02）。
结论
如果渗漏性视网膜裂孔位于扣带上，气体性视网膜固定术是翻修手术的有效替代方法。
