To identify the characteristics predictive of unfavorable outcomes for pneumatic retinopexy (PR) in the repair of pseudophakic rhegmatogenous retinal detachments (RD).
A retrospective chart review was performed at a single institution to identify patients who underwent PR in pseudophakic eyes. Pre- and postoperative data were reviewed and analyzed to evaluate predictive factors of failure.
Forty-four patients met the study criteria. PR was successful in 23 (52.3%) patients. The failed cases underwent scleral buckles, vitrectomies, or both. A retinal tear located outside the superior four clock hours was a significant predictor of PR failure. At six months post-intervention, the failure and success groups were statistically similar for vision and rate of reattachment.
Modified criteria for PR in pseudophakia may include cases with retinal breaks within the superior four clock hours. If further surgery is required, the final vision and anatomic reattachment are not disadvantaged by the initial PR procedure.
确定在人工晶状体性孔源性视网膜脱离（RD）修复中，预测气体性视网膜固定术（PR）不良预后的特征。
在单一机构进行回顾性病历审查，以确定接受人工晶状体眼PR的患者。回顾并分析术前和术后数据，以评估失败的预测因素。
44例患者符合研究标准。23例（52.3%）患者PR成功。失败病例接受了巩膜扣带术、玻璃体切除术或两者兼施。位于上方四个钟点以外的视网膜裂孔是PR失败的重要预测因素。干预后六个月，失败组和成功组在视力和复位率方面在统计学上相似。
人工晶状体眼PR的改良标准可能包括上方四个钟点内有视网膜裂孔的病例。如果需要进一步手术，初始PR手术不会对最终视力和解剖复位产生不利影响。
