Abstract：
BACKGROUND: This study aimed to assess the effectiveness of 55° wide-field (WF) spectral-domain (SD) optical coherence tomography (OCT) for detecting peripheral subretinal fluid (SRF) after surgery for rhegmatogenous retinal detachment (RRD).
METHODS: In this retrospective observational study, the retinal periphery was examined to evaluate the possible presence of persistent SRF after surgery. OCT scans were acquired in infrared mode to use any peripheral vessel as a landmark for better repeatability in monitoring fluid remnants.
RESULTS: A total of 80 patients (10% with high myopia) were examined using 55° WF SD OCT after successful pars plana vitrectomy (83.8%) or scleral buckling (16.3%) for RRD. A total of 18 patients (22.5%), 16 of whom underwent pars plana vitrectomy and 2 who underwent scleral buckling, showed SRF at the OCT examination during the follow-up. Potential risk factors associated with SRF persistence were analyzed, revealing a significative association with young age (p = 0.009). After a follow-up period of 7.05 ± 2.44 months (ranging from 3 to 12 months), a complete resorption in all patients (100%) within 12 months was observed. Best-corrected visual acuity significantly improved in both groups over time.
CONCLUSIONS: Using 55° WF SD-OCT successfully assessed the course of SRF reabsorption, offering a viable alternative for all those realities where technologies such as ultra-wide-field (UWF) OCT are not available.

摘要：
背景：本研究旨在评估55°广角（WF）谱域（SD）光学相干断层扫描（OCT）检测孔源性视网膜脱离（RRD）手术后周边视网膜下液（SRF）的有效性。
方法：在这项回顾性观察研究中，我们检查了视网膜周边,以评估手术后是否存在持续性SRF.在红外模式下获取OCT扫描,以使用任何外周血管作为标志,以更好地重复监测液体残留物。
结果：共有80例患者（10%高度近视）在成功行玻璃体切割（83.8%）或巩膜扣带（16.3%）的RRD后使用55°WFSDOCT进行检查。共有18名患者(22.5%),其中16人接受了平坦部玻璃体切除术，2人接受了巩膜扣带术，随访期间OCT检查显示SRF。分析与SRF持续相关的潜在危险因素，揭示了与年轻年龄的显著关联(p=0.009)。经过7.05±2.44个月（3~12个月）的随访，观察到所有患者(100%)在12个月内完全吸收.随着时间的推移，两组的最佳矫正视力均有显着改善。
结论：使用55°WFSD-OCT成功评估了SRF重吸收的过程，为所有无法使用超广域(UWF)OCT等技术的现实提供可行的替代方案。
