Figure 2. Difference in axial length and equatorial diameter after induction of myopia

Differences in (A) axial length and (B) equatorial diameter with in form-deprived myopic (FDM), internal control (FC), and normal (N) eyes of guinea pigs. Axial lengths of the FDM eyes with digital caliper measurements were significantly greater than those of control eyes, but equatorial diameters did not significantly differ in FDM versus control eyes. The asterisk indicates p<0.05 and the double asterisks denote p<0.01. Data are the mean±standard error of the mean.
