ABSTRACT
<p><b>INTRODUCTION</b>For occipital cortex strokes resulting in vision disorders, questions about the viability of residual visual cortex remain.</p><p><b>CLINICAL PICTURE</b>In a patient with a one-year-old, left, complete, homonymous hemianopia due to a right, posterior cerebral artery, ischaemic infarct, we assessed the visual cortex with fMRI retinotopic mapping prior to starting vision restoration therapy.</p><p><b>OUTCOME</b>The patient was found to have residual neurovascular function and retinotopic representation in the surviving visual cortex around the infarcted area.</p><p><b>CONCLUSION</b>The ability to respond to stimuli in part of the blind field, though not consciously perceived, suggests the potential for recovery.</p>
