NRG1 and myopia: Comparing the NRG-1 antibody groups with the myopia group, both the sclera and retina were thicker at the posterior pole (p ≤ 0.001 and p = 0.10, respectively), and the sclera was also significantly thicker at the equator (p = 0.006), in the low-dose NRG-1 antibody group than in the myopia group.
