To quantify the environmental impact of pars plana vitrectomy (PPV), pneumatic retinopexy, and scleral buckle procedures used in rhegmatogenous retinal detachment (RRD) repair. We conducted a life cycle assessment of PPV, pneumatic retinopexy, and scleral buckle procedures. The primary outcome measure was the greenhouse gas emissions associated with each procedure measured in carbon dioxide equivalents. The total greenhouse gas emissions produced were 51.10 kg carbon dioxide equivalents for PPV, 2.09 kg carbon dioxide equivalents for pneumatic retinopexy, and 12.57 kg carbon dioxide equivalents for scleral buckle. Emissions related to equipment use (30.07 kg carbon dioxide equivalents) followed by equipment manufacturing (21.00 kg carbon dioxide equivalents) were the main contributors of greenhouse gases in PPV. Emissions related to equipment manufacturing (1.60 kg and 8.51 kg of carbon dioxide equivalents for pneumatic retinopexy and scleral buckle, respectively), followed by equipment use (0.49 kg and 4.05 kg of carbon dioxide equivalents for pneumatic retinopexy and scleral buckle, respectively), were the greatest contributors of greenhouse gases in pneumatic retinopexy and scleral buckle. There is a substantial difference in greenhouse gas emissions among PPV, pneumatic retinopexy, and scleral buckle. Quantifying and understanding these differences can inform surgical decision-making.
为了量化用于孔源性视网膜脱离（RRD）修复的玻璃体切割术（PPV）、气体视网膜固定术和巩膜扣带术的环境影响。我们对PPV、气体视网膜固定术和巩膜扣带术进行了生命周期评估。主要结局指标是与每个手术相关的以二氧化碳当量衡量的温室气体排放。PPV产生的温室气体排放总量为51.10千克二氧化碳当量，气体视网膜固定术为2.09千克二氧化碳当量，巩膜扣带术为12.57千克二氧化碳当量。PPV中，与设备使用相关的排放（30.07千克二氧化碳当量），其次是设备制造（21.00千克二氧化碳当量），是温室气体的主要贡献者。气体视网膜固定术和巩膜扣带术中，与设备制造相关的排放（气体视网膜固定术和巩膜扣带术分别为1.60千克和8.51千克二氧化碳当量），其次是设备使用（气体视网膜固定术和巩膜扣带术分别为0.49千克和4.05千克二氧化碳当量），是温室气体的最大贡献者。PPV、气体视网膜固定术和巩膜扣带术之间的温室气体排放存在显著差异。量化并理解这些差异可为手术决策提供参考。
