A program involving three operations-the first to reattach most of the retina under silicone oil, the second to reattach the remaining retina by planned delayed relaxing retinectomy (PDRR), and the third to remove silicone oil-was tested.
Review of electronic records of patients receiving PDRR for proliferative vitreoretinopathy (PVR). The primary end point was reattached retina without silicone oil.
Eighty-seven patients had PVR and 27 received PDRR (mean age: 66.6 years; mean follow-up: 2.3 years). Ten patients had grade B PVR, 8 had CP1 to CP6, and 7 had CA2 to CA6. Twenty-four (89%) patients achieved a reattached retina without silicone oil. Mean logarithm of the minimum angle of resolution visual acuities were 1.41 (standard deviation = 0.67) at presentation and 1.21 (standard deviation = 0.58) at final follow-up. Four patients had glaucoma and 1 had scleromalacia. The overall success rate for all patients with PVR was 85% reattached retina without oil tamponade.
PDRR contributes to a high chance of reattached retina and oil removal in PVR.
对一个包含三项手术的方案进行了测试，第一项手术是在硅油下重新附着大部分视网膜，第二项手术是通过计划性延迟放松性视网膜切除术（PDRR）重新附着剩余视网膜，第三项手术是取出硅油。
回顾接受PDRR治疗增生性玻璃体视网膜病变（PVR）患者的电子病历。主要终点是无硅油情况下视网膜重新附着。
87例患者患有PVR，27例接受了PDRR（平均年龄：66.6岁；平均随访时间：2.3年）。10例患者为B级PVR，8例为CP1至CP6，7例为CA2至CA6。24例（89%）患者实现了无硅油情况下视网膜重新附着。初诊时最小分辨角视力的平均对数为1.41（标准差=0.67），末次随访时为1.21（标准差=0.58）。4例患者患有青光眼，1例患有巩膜软化症。所有PVR患者的总体成功率为85%，即无硅油填充情况下视网膜重新附着。
PDRR有助于PVR患者视网膜重新附着和取出硅油的高成功率。
