Figure 1. Refractive state and vitreous chamber depth of marmoset eyes following binocular +5 D and -5 D lens treatment over 92 days. A: −5 D lens-treated eyes (open symbols) exhibited a more negative refractive error relative to contralateral +5 D lens-treated eyes (closed symbols). B: −5 D lens-treated eyes (open symbols) exhibited longer vitreous chambers relative to contralateral +5 D lens-treated eyes (closed symbols). Eyes of the four individual marmosets are represented by different symbols (red circle, subject A; green square, subject B; black triangle, subject C; blue diamond, subject D).
