Aim. To investigate the anatomical success rates of pars plana vitrectomy (PPV) after primary rhegmatogenous retinal detachment (RRD). Methods. This retrospective study was conducted between December 2008 and October 2014 at Nagasaki University Hospital. The preoperative data recorded included the lens status, location of the retinal tear, whether a tear was visualized, presence of multiple tears, macula status, presence of peripheral lattice retinal degeneration, and best-corrected visual acuity (BCVA). The primary outcome measures were anatomical (primary and final) and functional success (visual acuity better than 6/60). Results. This study evaluated 422 eyes of 411 patients with a mean age of 57.7 ± 11.2 years. The single-operation reattachment rate (primary anatomical success) was 89.8%. The final anatomical success rate was 100% after 2-6 operations (mean = 3.14 ± 1.03). Functional success rate after the primary reattachment operation was 96.7%, while it was 97.2% at the end of the follow-up. Multiple logistic regression analysis of the possible risk factors for the primary anatomical failure showed a significant relation with the 25 G instruments (P = 0.002) and the presence of multiple tears (P = 0.01). Conclusion. The primary anatomical success of PPV for primary uncomplicated RRD was 89.8% and the final anatomical success rate was 100%.
目的。探讨原发性孔源性视网膜脱离（RRD）后玻璃体切割术（PPV）的解剖学成功率。方法。本回顾性研究于2008年12月至2014年10月在长崎大学医院进行。记录的术前数据包括晶状体状态、视网膜裂孔位置、裂孔是否可见、多个裂孔的存在、黄斑状态、周边视网膜格子样变性的存在以及最佳矫正视力（BCVA）。主要观察指标为解剖学（初次和最终）和功能成功率（视力优于6/60）。结果。本研究评估了411例患者的422只眼，平均年龄为57.7±11.2岁。单次手术复位率（初次解剖学成功）为89.8%。经过2 - 6次手术（平均=3.14±1.03）后，最终解剖学成功率为100%。初次复位手术后的功能成功率为96.7%，而随访结束时为97.2%。对初次解剖学失败的可能危险因素进行的多因素逻辑回归分析显示，与25G器械（P = 0.002）和多个裂孔的存在（P = 0.01）有显著关系。结论。PPV治疗原发性单纯性RRD的初次解剖学成功率为89.8%，最终解剖学成功率为100%。
