Figure 5. Histological sections of RPGRIP1-deficient dog’s retinas. A: Normal dog NA2 at the age of 2 months. B: Affected dog A6 at the age of 2 months. C: Affected dog A1 at the age of 11 months. D: Affected dog A2 at the age of 28 months. E: Affected dog A5 at the age of 10 years. These results confirm the thinning of the retina observed on OCT images. Abbreviations: retinal pigment epithelium (RPE); outer segments (OS); inner segments (IS); outer nuclear layer (ONL); outer plexiform layer (OPL); inner nuclear layer (INL); inner plexiform layer (IPL); ganglion cell layer (GCL). The scale bar represents 100 µm.
