Emmetropization There was strong evidence of emmetropization (Figures 4(a) and 4(b) ) in RAR and ROP Sprague-Dawley rats ( dashed light blue and light red lines ) as well as ROP Long-Evans rats ( dark red lines ) resulting in a highly significant effect of age ( F (age) = 32.6, df = 2,78, P < 10 −10 ).
