Figure 1. Bilateral full-field electroretinographic recordings of RPGRIP1-deficient dogs. A: Heterozygous carrier NA1 at the age of 6 months. B: Affected dog A1 at the age of 2, 4, and 9 months. C: Affected dog A2 at the age of 2, 4, 9, and 12 months. D: Affected dog A3 at the age of 2, 4, 9, and 12 months. E: Affected dog A4 at the age of 2, 4, 9, and 12 months. The top two recordings are low and high intensity scotopic responses. The bottom two recordings show photopic responses to light-adapted single flash and 30 Hz flicker stimuli.
