Figure 3. Correlation between conjunctival injection, conjunctival edema, papillary formation, corneal epithelial cell damage and ECP levels. ECP concentrations showed a significant correlation with conjunctival injection scores (A: r=0.65, p=0.0044). ECP concentrations did not show any correlation with papillary proliferation scores (B: r=-0.03, p=0.9810). ECP concentrations showed a significant correlation with conjunctival edema scores (C: r=0.60, p=0.0114).  ECP concentrations showed a significant correlation with fluorescein staining scores (D: r=0.70, p=0.0039).
