To describe the demographic, clinical, and en face OCT features of eyes with epiretinal membrane (ERM) with or without internal limiting membrane (ILM) tears.
Retrospective case series.
This single-institution study included 101 eyes of 101 patients with ERM.
This single-institution study included 101 eyes of 101 patients with ERM.
Demographic and clinical data were collected from the electronic medical record. En face OCT of the ERM was reviewed and studied in every case and the prevalence of ILM tears was determined. Various en face OCT biomarkers associated with ILM tears were also evaluated including nerve fiber layer defects (NFLDs), which were classified as NFLD round (R), i.e., paravascular inner retinal defects (PIRDs), vs. NFLD oval (O) (i.e., inner retinal dimples [IRDs]). Schisis of the retinal nerve fiber layer (SNFL) and posterior vitreous detachment (PVD) grade were also assessed.
Internal limiting membrane tears were identified in 21 of 101 eyes (20.8%) with ERM. No significant differences in demographic or clinical characteristics were observed between ERM eyes with or without ILM tears. However, NFLDs (R) (i.e., PIRDs) were significantly (P < 0.05) more common (80.9% vs. 37.5%) in the ILM tear group vs. the non-ILM tear group. This was also the case for SNFL (57.1% vs. 12.5%) and grade 4 PVD (100% vs 68.7%). Additionally, NFLDs (O) (i.e., IRDs) were only present in the ILM tear group (52.4% vs. 0%).
Eyes with ILM tear exhibit several associated imaging biomarkers suggestive of progressive ERM contracture and/or vitreoretinal traction as compared with eyes without ILM tears including various forms of NFL defects and schisis of the nerve fiber layer. En face OCT, especially when widefield, may serve as a supportive tool to identify the various pathoanatomical lesions associated with ILM tears with single acquisition.

描述伴有或不伴有内界膜（ILM）撕裂的视网膜前膜（ERM）患者眼睛的人口统计学、临床和OCT表面成像特征。
回顾性病例系列研究。
这项单机构研究纳入了101例患有ERM的患者的101只眼睛。
这项单机构研究纳入了101例患有ERM的患者的101只眼睛。
从电子病历中收集人口统计学和临床数据。对每例患者的ERM进行OCT表面成像检查并研究，确定ILM撕裂的发生率。还评估了与ILM撕裂相关的各种OCT表面成像生物标志物，包括神经纤维层缺损（NFLD），分为NFLD圆形（R），即血管旁视网膜内层缺损（PIRD），与NFLD椭圆形（O）（即视网膜内层凹陷[IRD]）。还评估了视网膜神经纤维层（SNFL）的劈裂和玻璃体后脱离（PVD）分级。
在101只患有ERM的眼睛中，有21只（20.8%）发现了内界膜撕裂。伴有或不伴有ILM撕裂的ERM患者在人口统计学或临床特征上未观察到显著差异。然而，NFLD（R）（即PIRD）在ILM撕裂组中显著（P<0.05）更常见（80.9%对37.5%），而非ILM撕裂组。SNFL（57.1%对12.5%）和4级PVD（100%对68.7%）也是如此。此外，NFLD（O）（即IRD）仅出现在ILM撕裂组（52.4%对0%）。
与没有ILM撕裂的眼睛相比，伴有ILM撕裂的眼睛表现出几种相关的成像生物标志物，提示ERM进行性挛缩和/或玻璃体视网膜牵拉，包括各种形式的NFL缺损和神经纤维层劈裂。OCT表面成像，尤其是广角成像时，可作为一种辅助工具，通过单次采集识别与ILM撕裂相关的各种病理解剖病变。
