^§Temporal RNFLT used for correlation with mfVEP central 5.6° and 10–2 RVS, average RNFLT used for others.

^†Statistically different from the corresponding correlation with RNFLT in the same group (p < 0.001 for central, 0.01 for global after Bonferroni correction).

^*Statistically different (p < 0.05) from the corresponding correlation with MfVEP Latency only before Bonferroni correction.
