Figure 5. The diffusion coefficient of sodium fluorescein (NaF) in the sclera

The data were obtained through the curve-fitting shown in Figure 4A. The bar and error bar represent mean and SD, respectively. The diffusion coefficient of NaF was 5.23±1.93x10^-7 cm²/s (n=8) in scleras stored at 4 °C for 4 h, 5.68±4.57x10^-7 cm²/s (n=4) in scleras stored at 4 °C for 3 days, or 5.40±2.76x10^-7 cm²/s (n=11) when NaF diffused simultaneously with ethacrynic acid (ECA) through the same sclera. There were no statistically significant differences between any two groups (p>0.05).
