PURPOSE To investigate the effect of 360° intra-operative laser retinopexy (ILR) for the prevention of retinal re-detachment in patients treated with pars plana vitrectomy (PPV) for primary rhegmatogenous retinal detachment (RRD). METHODS A retrospective single-institution cohort study was performed. Consecutive patients with primary uncomplicated RRD who underwent 23-gauge PPV with gas endotamponade between July 2013 and July 2016 were included in the study (n = 151). Two cohorts were compared: one which received laser retinopexy only around identified tears/holes/lattice zones (Control group, n = 86), and one which received additional 360° intra-operative laser retinopexy (360° ILR group, n = 65). RESULTS Retinal re-detachment was seen in 4/65 eyes (6%) in the 360° ILR group compared to 18/86 eyes (21%) in the control group. In multiple logistic regression, the 360° ILR was associated with a 75% reduction in the odds of retinal re-detachment compared to control (OR = 0.248, 95% CI [0.079-0.772], p = 0.016). There was no statistically significant difference in the incidence of epiretinal membrane formation between the two groups. CONCLUSIONS Intra-operative 360° laser retinopexy during PPV with gas endotamponade resulted in a significant reduction in the odds of postoperative retinal re-detachment in eyes with uncomplicated primary RRD.

360度术中激光视网膜手术预防原发性pars玻璃体切除术患者的视网膜再脱离。

目的探讨360°术中激光视网膜色素变性（ILR）预防原发性血源性视网膜脱离（RRD）的经pars平板玻璃体切除术（PPV）治疗的患者的视网膜再脱离的作用。方法进行回顾性单机构队列研究。该研究纳入了2013年7月至2016年7月期间接受23规格PPV气腹内压治疗的原发性单纯性RRD连续患者（n = 151）。比较了两个队列：一个仅在确定的眼泪/孔/晶格区域周围接受激光视网膜镜检查（对照组，n = 86），另一组则接受额外的360°术中激光视网膜镜检查（360°ILR组，n = 65）。 。结果在360°ILR组中，视网膜再脱离发生在4/65眼（6％）中，而在对照组中则是18/86眼（21％）。在多对数回归中，与对照组相比，360°ILR与视网膜再脱离几率降低75％相关（OR = 0.248，95％CI [0.079-0.772]，p = 0.016）。两组之间视网膜上膜形成的发生率无统计学差异。结论PPV术中进行气管内填塞术期间术中360°激光视网膜镜检查可显着降低单纯RRR术后眼睛视网膜再脱离的几率。
