Figure 2. (A) Mean GAG synthesis in scleras from eyes wearing lenses. Scleras from eyes wearing 215D lenses synthesize more GAGs than eyes wearing +15D lenses (p < 0.01). (B) Mean axial length in both groups of birds: “binocular lenses” denote birds wearing a +15D lens on one eye and a 215D lens on the fellow eye; “monocular lenses” denote birds wearing +15D or 215D lenses on one eye and a plano lens on the fellow eye (number of eyes noted above bars). The axial length in the eyes wearing 215D lenses are significantly longer than those wearing +15D lenses for both groups.
Figure 3. (A) Mean GAG synthesis in choroids from eyes wearing lenses (number of eyes same as in Fig. 2A). The choroids in eyes with myopic defocus (+15D lenses) synthesize more GAGs than those from eyes with hyperopic defocus (215D lenses) (p < 0.001); choroids from the 215D eyes also synthesize fewer GAGs than eyes wearing plano lenses (p < 0.05). (B) Mean thickness of the choroid + retina in both groups of birds (number of eyes same as in Fig. 2B). Choroid + retinas from eyes with myopic defocus (+15D lenses) are thicker than those from eyes with hyperopic defocus (215D lenses) as well as eyes wearing plano lenses.
Figure 1. Refractive error and vitreous chamber depth in eyes wearing +15D, plano and 215D spectacle lenses. (A) Refractive error. Eyes compensated for myopic defocus (+15D lenses) by becoming hyperopic, and for hyperopic defocus ( 215D lenses) by becoming myopic. (B) Vitreous chamber depth. The eyes compensating for myopic defocus had the smallest, vitreous chamber depths and eyes compensating for hyperopic defocus the largest. Vitreous chambers of eyes wearing plano lenses were intermediate in length. (C) Refractive error as a function of vitreous chamber depth. The line shows the regression; there is a significant correlation between the two variables (r = 0.71, p < 0.001), suggesting that the changes in refractive error are due to changes in the length of the vitreous chamber. Error bars are standard errors of the mean.
