Mapping infarct location in patients with visual field deficit

Stroke affecting the visual pathway cause considerable disability due to impairment of visual field and driving. Previous study have suggested that quadrantanopic field deficit is due to smaller infarcts than those causing hemianopic field deficit but have not provide a rationale for the difference. The aim of this study is to map the association between infarct location on MRI and visual field deficit in order to better understand the nature of difference between infarcts causing hemianopia and quadrantanopia. Learning objectives include analysis of diffusion tensor imaging to evaluate interruption of optic radiation as well as quantitative analysis of visual field.
