摘　　要：特发性视网膜前膜(idiopathic epiretinal membrane,iERM)是一种病因未明的可引起视觉质量下降的眼科疾病,可通过持续牵拉使视网膜出现复杂多样的改变。光学相干断层扫描成像(optical coherence tomography,OCT)能够清晰显示iERM引起的视网膜特征性改变。在视网膜内层,不同形态的特发性视网膜前膜可产生不同的视力预后;异位中心凹内层的出现是视力下降的危险因素;内核层增厚可导致视物变形,而视网膜囊性腔隙可能与Müller细胞损伤有关。在视网膜外层,椭圆体带、嵌合体带以及棉球征可评估感光细胞受损程度。论文就近年来iERM患者的OCT特征性改变进行综述。Idiopathic epiretinal membrane(iERM)is a medically unexplained ophthalmic disease that can cause a decline in vision quality due to complex and diverse changes in the retina through continuous vitreomacular traction.Optical coherence tomography(OCT)can clearly display the characteristic changes to the retina caused by iERM.In the inner retina,different forms of iERM can produce different visual prognoses.For example,the appearance of ectopic inner foveal layers is a risk factor for vision loss,thickening of the inner nuclear layer can cause visual distortion,and intraretinal cystic spaces may be related to injured Müller cells.In the outer retina,the integrity of the ellipsoid zone,interdigitation zone,and the cotton ball sign can indicate the degree of photoreceptor damage.This article reviews the characteristic changes visible on OCT in patients with iERM.
