Fig. 1From: Preoperative imaging optimized for epiretinal membrane surgeryPreoperative and intraoperative images of a case of idiopathic epiretinal membrane (ERM). Color Fundus Photography (a) shows the reflectivity of the ERM in the temporo-macular area (arrow). Intraoperatively (b), the differential staining of the ILM and ERM allows visualizing ERM limits; the blue dye stains the ILM (arrowhead) but not the ERM, giving this ‘negative’ aspect. En Face OCT (c) and Blue Reflectance (d) images show a remarkable plaque-like aspect (arrow) surrounded by a retinal folding (arrowhead). The infrared reflectance image (e) also shows the ERM (arrow) but its limits are barely visible. Horizontal (f) and vertical (g) OCT B-scan images show the ERM (arrow), retinal folds (arrowhead) and convex macular thickeningBack to article page
