Ultrasound biomicroscopy images of two normal monkey eyes, aged 6 years (A, C) and 23 years (B, D), in the unaccommodated and accommodated states. The change in angle between the anterior aspect of the ciliary body and the inner aspect of the cornea during supramaximal central stimulation was used as a surrogate indicator of forward ciliary body movement (FCB) (Croft et al., 2006a). Panels B and D adapted with permission from: Croft et al. Accommodative Ciliary Body and Lens Function in Rhesus Monkeys I. Normal lens, zonule and ciliary process configuration in the iridectomized eye. Invest Ophthalmol Vis Sci 2006;47:1076-1086.
