Figure 2. Increased vascular endothelial cell count in eyes with proliferative diabetic retinopathy (PDR) was suppressed by pretreatment of intravitreal bevacizumab (IVB). The epiretinal membranes of proliferative vitreoretinopathy (PVR) eyes were set as the control group. Quantitative analysis for the vascular endothelial cell count in the neovascular membranes (NVMs) of PDR eyes and epiretinal membranes of PVR eyes was determined by counting positively stained cells in 10 representative fields. Each value represents means±SEM from three independent experiments (p=0.003).
