Figure 5.

Relative changes in refractive error for the lens-treated eyes of individual vehicle controls (A) and caffeine monkeys reared with −3D (B) and +3D of imposed anisometropia (C) plotted as a function of age. The data were normalized to the refractive corrections at the start of the treatment period. The first and last symbols in each individual function represent the start and end of the treatment period, respectively. The red line in each plot shows the median refractive-error changes observed in normal control animals. (D) Ametropias obtained at ages corresponding to the end of the lens-rearing period for individual animals. The right and left eyes of the normal monkeys are represented by open symbols. For the lens-reared animals, the filled and open symbols represent the lens-treated and control eyes, respectively
