Fig. 1

Representative retinal imaging of idiopathic epiretinal membrane (ERM). a, b Representative color fundus photography (CFP) and fundus autofluorescence (FAF) images of idiopathic ERM in Group 1 without ectopic inner foveal layer (EIFL). White arrowhead represents a retinal vessel branch strained by ERM. c, d Representative CFP and FAF images of idiopathic ERM in Group 2 with EIFL. Red arrowhead represents the distorted retinal vessel branch strained by tractional forces of ERM in EIFL eyes. Yellow arrows show the feeble spots of autofluorescence near macular fovea
