Figure 4. The average number of Ki-67 labeled cells/mm2 of membrane for the four disease conditions plotted from the total Ki-67/mm2 data in Table 1. PVR membranes had the highest number of dividing cells at 138.3/mm2, with proliferative diabetic retinopathy (PDR) at 20.9, epiretinal membranes post–retinal detachment (ERMpRD) at 12.2, and idiopathic ERM (iERM) at 19.3. Error bars represent the standard deviation.
