This study evaluated if emmetropia, achieved in broadband colony lighting, is maintained in narrow-band cyan light that is well focused in the emmetropic eye, but does not allow for guidance from longitudinal chromatic aberrations (LCA) and offers minimal perceptual color cues. In addition, this study examined the response to a −5 D lens in this lighting.
In monkeys and tree shrews, narrow-band red light disrupts emmetropization, slowing axial eye growth and producing substantial hyperopia. We asked whether exposure to ambient amber light (lower cutoff - 530 nm), which also stimulates only the …
We investigated the effect of systemic administration of 7MX on induced myopia in tree shrews and showed that oral 7MX appears to have either no, or very limited influence on compensatory refractive responses.
In practice, initiating 0.01% atropine treatment for a child would inevitably delay implementation of an effective dose. This is particularly problematic in the early stages of myopia development when progression is most rapid. Since the sight‐threatening complications of myopia result primarily from excessive tissue stretch, effective slowing of eye growth would significantly ameliorate the risks and consequently help reduce the burden of future sight loss.
This thesis uses advanced imaging and electrophysiology techniques to investigate the in vivo phsiological responses of human retina and choroid to retinal image defocus and improves our understanding the mechanistic basis of myopia.
