Abstract：
OBJECTIVE: To investigate epiretinal membrane (ERM) formation using en face optical coherence tomography (OCT) after vitrectomy for rhegmatogenous retinal detachment (RRD).
METHODS: We retrospectively reviewed the medical records of 64 consecutive eyes (64 patients) with RRD treated by vitrectomy without ERM and internal limiting membrane peeling. ERMs and retinal folds were detected by B-scan and en face imaging. The maximum depth of retinal folds (MDRF) was quantified using en face imaging. ERM severity was staged using B-scan imaging. Main outcome measures were ERM detection rate with B-scan and en face imaging, MDRF, ERM staging, postoperative best-corrected visual acuity (BCVA; logarithm of the minimum angle of resolution), and risk factors for ERM formation.
RESULTS: The detection rate for ERM formation was significantly higher with en face imaging (70.3%) than with B-scan imaging (46.9%; P = 0.007). There was no significant difference in postoperative BCVA between eyes with ERM formation (0.06 ± 0.26) and those without ERM formation (0.01 ± 0.14; P = 0.298). Forty of 45 (88.9%) eyes with ERM formation were classified as stage 1. Twenty-seven of 45 (60.0%) eyes with ERM formation developed parafoveal retinal folds. The mean MDRF was 27.4 ± 32.2 μm. Multiple retinal breaks and a maximum retinal break size of ≥ 2 disc diameters were significantly associated with ERM formation (P = 0.033 and P = 0.031, respectively).
CONCLUSIONS: Although ERM formation was observed in 70.3% patients after RRD repair, the formed ERM was not severe and had minimal impact on the postoperative visual acuity.

摘要：
目的：使用面部光学相干断层扫描（OCT）研究玻璃体切除术治疗孔源性视网膜脱离（RRD）后视网膜前膜（ERM）的形成。
方法：我们回顾性回顾了64例（64例）接受无ERM和内界膜剥离的玻璃体切除术治疗的RRD患者的病历。通过B扫描和面部成像检测ERM和视网膜皱褶。使用面部成像量化视网膜褶皱的最大深度(MDRF)。使用B扫描成像对ERM严重程度进行分级。主要结局指标是B超和面部成像的ERM检出率，MDRF,ERM分期,术后最佳矫正视力（BCVA；最小分辨率角度的对数），以及ERM形成的危险因素。
结果：面部成像对ERM形成的检出率（70.3%）明显高于B超成像（46.9%；P=0.007）。有ERM形成的眼(0.06±0.26)和无ERM形成的眼(0.01±0.14;P=0.298)术后BCVA无显著差异。45只（88.9％）的ERM形成眼被归类为1期。ERM形成的45只眼睛中有27只（60.0％）出现了旁凹视网膜褶皱。平均MDRF为27.4±32.2μm。多次视网膜破裂和≥2个椎间盘直径的最大视网膜破裂大小与ERM形成显着相关（分别为P=0.033和P=0.031）。
结论：尽管在RRD修复后70.3%的患者中观察到ERM形成，形成的ERM并不严重,对术后视力影响最小.
