Figure 6. Reduced amplitude of the Ganzfeld ERG in pilot-treated eyes is reversed in sPBS-treated eyes. A: Representative recordings of scotopic Ganzfeld electroretinograms (ERGs) in the untreated and pilot- and subretinal PBS injection (sPBS)-treated eyes. B: The amplitudes of the scotopic a- and b-waves were statistically significantly reduced in the pilot-treated eyes (*p<0.05, **p<0.01, ***p<0.001, n=10) compared to the untreated eyes (n=9). The amplitude of the a-wave, but not the b-wave, was statistically significantly smaller in the sPBS-treated eyes compared to the untreated eyes (†††p<0.001, n=10). The b-wave was increased in the sPBS-treated eyes compared to the pilot-treated eyes (‡p<0.05). Note that a- amplitude is usually negative but is recorded as a positive absolute value for ease in comparison.
