We reviewed previous publications reporting the SD-OCT findings of animal models of RP and summarized the characteristic findings of SD-OCT in nine different animal models (RCS–/–, RHO P23H, RHO S334ter, RHO–/–, Rpe65–/–, rp12, Pde6β–/– (rd1 and rd10), and Arr1–/–) of human RP. This evidence concerns the gene ARRB1 and retinitis pigmentosa 1.
