Investigating the human visual system in the absence of light input
Damage to the primary visual cortex leads to loss of the visual field contralateral to the damaged cortex. However, in spite of this loss, some patients are still able to detect visual information about stimuli presented within their blind field. A growing area of research aims to exploit this residual visual to try to improve visual performance through rehabilitation programmes stimulating the blind field. However, to optimise such programmes it is important to understand the pathways through which this information is conveyed.
Here I will present a series of functional magnetic resonance imaging studies in which we attempted to elucidate these pathways in a group of hemianopic patients, some with, and some without residual vision. I will also discuss a diffusion-tensor study in which we quantified the white matter microstructure of visual pathways in these patients to determine any differences in those with and without residual vision.
