Changes in refraction and vitreous chamber depth of infant monkeys in AL and NL.
(A) Spherical-equivalent refractive error and (B) vitreous chamber depth plotted as a function of time of lens wearing for infant monkeys reared under artificial lighting (AL) and natural lighting (NL) respectively. Each point represents the mean±SE (bar) of 8 eyes from the same group.

Interocular differences in refraction and ocular parameters of infant monkeys in AL and NL.
The interocular differences in spherical-equivalent refractive error (A-B), vitreous chamber depth (C-D) and corneal power (E-F) plotted as a function of time of lens wearing for individual infant monkeys reared under natural lighting (left panel) and artificial lighting (right panel) respectively.

Fig 3.
Refractive errors of adolescent monkeys in the three groups.
Spherical-equivalent refractive error measured at adolescence for the right (○) and left (●) eyes of individual monkeys from the three groups: (1) aged-matched normal group (Control), (2) NL group (Sunlight),(3) AL group (Artificial). The lines connect the right and left eyes of individual monkeys. The right eyes in the AL and NL group were treated with minus lenses early in life and the left eyes were contralateral eyes.

Relationship between anisometropia and interocular differences in vitreous chamber depth of adolescent monkeys in the three groups.
Absolute interocular differences in spherical-equivalent refractive error plotted as a function of interocular differences in vitreous chamber depth for individual animals. Solid line: best-fitting regression line (y = -1.921x-0.091; r2 = 0.769).
Fig 5.
Anisometropia and interocular differences in vitreous chamber depth of adolescent monkeys in the three groups.
Interocular differences in Spherical-equivalent refractive error (A) and vitreous chamber depth (B) measured for adolescent monkeys from three groups: (1) aged-matched normal group (Control), (2) NL group (Sunlight), (3) AL group (Artificial). Data columns represent the means±SE (bars).
