Figure 2. MMP9 levels in the serum from early AMD (n=75), nAMD (n=89), PCV (n=98), and control subjects (n=80) were measured with ELISA.
One-way ANOVA with a post-hoc Scheffe test demonstrated that the serum concentration of MMP9 in the PCV group was significantly
higher than that of the control (p<0.001), early AMD (p<0.001), and nAMD groups (p=0.001). Abbreviations: AMD=Age-related
macular degeneration; nAMD=neovascular Age-related macular degeneration; PCV=Polypoidal choroidal vasculopathy; ELISA=Enzyme-linked
immunosorbent assay.
