Physiological responses of human retina and choroid to retinal image defocus: Implications for myopia
… guided by local regulation of eye growth. The retina and choroid have been implicated in detecting defocus and relaying information to the sclera to control eye size and thus maintain emmetropia. However, the mechanisms underlying retinal and choroidal responses to defocus remain unclear. Aims: …

Neuronal Diversification Within the Retina: Generation of Crossed and Uncrossed Retinal Ganglion Cells
… and their corresponding axon projections. Retinal axon divergence at the optic chiasm midline is key to the establishment of binocular vision in higher vertebrates. In the visual system of binocular animals, the ipsilaterally and contralaterally projecting retinal ganglion cells are …

Chromatic sensitivity: effects of light level and selective photoreceptor adaptation
… The effect of adapting different areas of the peripheral retina when thresholds are measured foveally was also investigated. No long range retinal interactions were observed. The results show that the adaptation state of the periphery has no effect on colour detection thresholds made in central …

Peripheral Dynamic Visual Acuity Under Randomized Tracking Task Difficulty, Target Velocities, and Direction of Target Presentation
… and dynamic acuity in the 25-55 deg region of retinal eccentricity under a variety of conditions. Functionally, this region of the visual field is just beyond the "blind spot," but not yet in the "far" visual periphery of 60-90 deg of eccentricity. Traditionally, DVA research has been confined …

Investigating the integrity of the vasculature and structural relationships of pericytes, astrocytes and the endothelial glycocalyx in an ex vivo hyperglycaemic rat retinal model
… is characterised by the degeneration of the retinal microvascular and neural components that form the blood retinal barrier (BRB), and is due to diabetic metabolic derangements such as hyperglycaemia. The cellular components of the BRB include endothelial cells, pericytes and the glial cells …

Exploring retinal changes in Dementia and Multiple Sclerosis
… It has been hypothesized that changes in the retina may mirror changes in the brain. In contrast to brain imaging, imaging the eye is quick, non-invasive, inexpensive and might offering a unique “window to the brain” To test this hypothesis eye imaging studies were set up of cohorts with …
