Full-field electroretinography (ffERG) responses in Mfrp KI/KI mice. (A) Representative averaged waveforms following stimulation under both scotopic and photopic conditions from 3.5-month-old WT mice compared to 3.5- and 6.5-month-old Mfrp KI/KI mice. (B) Graph of mean ffERG waveform amplitude under scotopic and photopic conditions depicting a- and b-wave responses to −3.5, −1.09, −2.00, and +1.09, +2.00 cd.s/m2 stimulation intensities, respectively, in Mfrp KI/KI compared to WT mice. Each point represents the mean, with error bars representing the standard deviation (n = 6).
