POU4F1 and myopia: Representative images of parafoveal ganglion cells stained with BRN3A can be seen in Figure 2A. The parafoveal ganglion cell density remained unchanged in controls as they grew (6 vs. 12-month-old control eyes, p > 0.05) but was significantly lower in the parafoveal retina of myopic marmosets induced with myopia for 4 months (Figure 2B, p < 0.05) and remained decreased after 10 months of induced myopia compared to controls (Figure 2B, p < 0.01).
