Visual function of RCS rats determined by the quantitative optomotor response (qOMR) in groups subjected to subretinal injection of different cells. A Photos of RCS rats used to evaluate the qOMR. B A range of stimuli at different spatial frequencies were used, including 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.375, 0.4, 0.425, 0.45, and 0.5 cycles/degree with movement at 12 degree/s for 60 s. The smaller the value of the spatial frequency, the greater the spacing of the black and white stripes is. C–F Heatmap of the average qOMR index values of different groups of RCS rats, which were subjected to subretinal transplantation or not injected with cells or PBS, at 1 week (C), 2 weeks (D), 3 weeks (E), and 4 weeks (F) post-injection. The higher the qOMR index is, the color is more blue. The lower the qOMR index is, the color is more white
