Self-separation or peeling of an idiopathic epiretinal membrane (ERM) in an eye with partial posterior vitreous detachment (PVD) is a rare event. A 56-year-old woman presented to our clinic with complaints of floaters in her right eye. Best-corrected visual acuity (BCVA) was 9/10 in this eye. Fundus examination and Spectral domain optical coherence tomography (SD-OCT) revealed an idiopathic ERM and Grade 3 PVD in this eye. Four months later, she had complaints of metamorphopsia in her right eye. BCVA was 7/10, while SD-OCT images of the right macula were similar to previous images. One week after the last visit, she presented again due to the sudden disappearance of her metamorphopsia complaints. BCVA had improved to 10/10. Fundus examination demonstrated that the ERM had spontaneously separated from the retinal surface as a flap floating in the vitreous and the foveal contour had returned to normal. The etiologic mechanism may be explained as the contracting forces within an immature ERM being stronger than its adhesion to the retina.
特发性视网膜内表面膜（ERM）在部分玻璃体后脱离（PVD）的眼中自行分离或剥脱是一种罕见的现象。一位 56 岁的女性因右眼出现漂浮物而到我科就诊。该眼最佳矫正视力（BCVA）为 9/10。眼底检查和频域光相干断层扫描（SD-OCT）显示该眼存在特发性 ERM 和 3 级 PVD。4 个月后，她右眼出现视物变形。BCVA 为 7/10，而右眼黄斑区的 SD-OCT 图像与之前的图像相似。最后一次就诊一周后，她因突然消失的视物变形而再次就诊。BCVA 已提高至 10/10。眼底检查显示 ERM 已自发地从视网膜表面分离，呈漂浮在玻璃体中的片状，黄斑区轮廓已恢复正常。其发病机制可能是由于不成熟的 ERM 内的收缩力比其与视网膜的黏附力更强。
