The inter-eye difference in axial length at study end increased (p < 0.001) from the normal control group (−0.02 ± 0.09 mm) and the myopia control group (−0.01 ± 0.09 mm) to the low-dose NRG-1 antibody group (−0.11 ± 0.05 mm), medium-dose NRG-1 antibody group (−0.17 ± 0.07 mm), and high-dose NRG-1 antibody group (−0.28 ± 0.06 mm). The gene discussed is NRG1; the disease is myopia.
