Figure 5
Plots illustrating the relationship between VF improvement and selected OCT (a,b) and VEPs (c,d) parameters. Higher is better for VF improvement, which was calculated as the difference between the last and the preoperative value of mean deviation (MD). The single dot represents one eye; the thick linear regression line is surrounded by dashed 99.9% and dotted 95.0% confidence intervals. A negative dependency between the VF improvement and preoperative state is evident in all plots. Such relationship illustrates a situation where the more affected initial state of the visual system is related to a higher benefit from the treatment. To note a statistically significant relationship between the improvement of and N160 amplitudes.
