Mean (±SE) spherical-equivalent refractive corrections (treated or right eyes, filled symbols; fellow or left eyes, open symbols) plotted as function of horizontal (left) and vertical (top) visual field eccentricities for the normal, NF (middle), and FF monkeys (bottom). For the NF and FF monkeys, the data were obtained at the end of the lens-rearing period (145 ± 11 and 147 ± 5 days, respectively); the normal monkey data were obtained at 162 ± 11 days of age.
