FIGURE 1.
(A) Refractive measures in the left and right eyes of a normal tree shrew (0451) starting at 16 days of VE (measurement day 1). The horizontal line at 4 D indicates estimated emmetropia as measured with the autorefractor. (B) The mean ± SEM refractive values for the left and right eyes of the normal-lighting group. (C) Distribution of refractive values for each eye of the five normal-lighting animals on measurement days 1, 12 and 44. Each shade of gray represents the two eyes of an individual animal. Bin width is 0.5 D. Vertical dashed line: estimated emmetropia as measured with the autorefractor.
