Work from animal models suggests that retinal defocus (or visual blur) initiates a signaling cascade that leads to a number of cellular and biochemical changes in the retina and the retinal pigment epithelium (RPE), which signal changes to the choroid, and eventually the sclera, leading to alterations in the overall growth and refractive state of the eye (Fig. 4.7). The retina is an integral part of this visual signaling as it is the first layer of photosensory neurons that detect defocus. Furthermore, ocular compensation for both FD and lens induced defocus are largely regulated at the retinal level. Severing the optic nerve in young chicks does not prevent the development of refractive errors in response to spec- tacle lenses or diffusers. In both chicks and primates, partial diffusers and hemifield spectacle lenses restricted to only half of the visual field cause corresponding myopic changes only in the visually deprived part of the globe. These studies demonstrate that the visual regulation of ocular growth in response to diffusers and lenses primarily occurs within the retina, with minimal input from the brain.
