AB  - PURPOSE: To investigate the effect of simultaneous dual-focus (DF) on retinal
      activities measured by global flash multifocal electroretinogram (mfERG).
      METHODS: Thirty adults were recruited for mfERG measurement under three
      conditions: in-focus (i.e., no defocus), +2.50 D DF and +7.50 D DF, administered 
      using single vision contact lenses and DF lenses. The direct component (DC) and
      the induced component (IC) of the mfERG were pooled into central macular (0-8
      degrees ), para-macular (8-18 degrees ) and peri-macular (18-30 degrees )
      regions, and then compared across the three conditions using two-way, repeated
      measures ANOVA. RESULTS: Simultaneous DF had a significant effect on the IC
      amplitude, which was significantly stronger under +7.50 D DF (p < 0.01) than for 
      the in-focus condition, which was mostly derived from the central and
      para-macular regions. No significant effect was observed for the +2.50 D DF
      condition. CONCLUSION: Under the effect of relatively strong simultaneous DF
      integration, the retina showed an enhanced retinal response, which originated
      from the inner retina. Compared with the peri-macular region, central and
      para-macular responses appeared to be enhanced.
