IFNγ pretreated exosomes protect retinal function in RP rats. A Chart of exosome infusion and schematic of the time point of the retinal function test. B Representative waveforms of the FERG test 2 weeks after exosome infusion at 3.0 cd*s/m² light intensity. C, D Comparison of a and b wave amplitudes at 2 weeks after exosome infusion (n > 10). E Representative waveforms of the FERG test 4 weeks after exosome infusion at 3.0 cd*s/m² light intensity. F, G Comparison of a and b wave amplitudes at 4 weeks after exosome infusion (n > 10). H Representative waveforms of the FERG test 6 weeks after exosome infusion at 3.0 cd*s/m² light intensity. I, J Comparison of a and b wave amplitudes at 6 weeks after exosome infusion (n > 10). K Representative waveforms of the FERG test 8 weeks after exosome infusion at 3.0 cd*s/m² light intensity. L, M Comparison of a and b wave amplitudes at 8 weeks after exosome infusion (n > 10). Data represent the mean ± SEM. ns: No significant difference, ∗P < 0.05, ∗∗P < 0.01, ∗∗∗P < 0.001, ∗∗∗∗P < 0.0001
