Figure 2. Metabolomic analysis for patients with PCG. A: Score plot for the first two components (t[1] and t[2]) between patients with CCs and PCG in the PLS-DA model. B: S plot for the two first components (w*c [1] and w*c [2]) between patients with CCs and PCG in the PLS-DA model. C: Score plot for the first two components (t[1] and t[2]) between patients with ARCs and PCG in the PLS-DA model. D: S plot for the two first components (w*c [1] and w*c [2]) patients with ARCs and PCG in the PLS-DA model. E: Score plot for the first two components (t[1] and t[2]) between patients with PCG and POAG in the PLS-DA model. F: S plot for the two first components (w*c [1] and w*c [2]) patients with PCG and POAG in the PLS-DA model. Significantly changed metabolites were labeled with a red triangle. PCG: primary congenital glaucoma; CCs: congenital cataracts; ARCs: aged-related cataracts; POAG: primary open angle glaucoma.
