Figure 1. Graph illustrating the mean length of time, in months, between diagnosis and epiretinal membrane removal for each disease condition. The duration the membranes were present in the eye ranged from 2 to 14 months for proliferative diabetic retinopathy (PDR), 0.25- 6 for proliferative vitreoretinopathy (PVR), 1–5 for epiretinal membrane post–retinal detachment (ERMpRD), and 4–25 for idiopathic ERM (iERM).
