[Correlation of infarctions of the visual cortex with homonymous visual field defects. A computer tomographic study...

Computed tomography (CT) is a simple and non-invasive method of demonstrating infarctions of the visual cortex. Seventy-eight CT-proven infarctions were correlated with the visual field defects. This correlation between cortical infarctions and visual field defects is difficult to achieve by angiography because of the variations in the vascular supply. CT, on the other hand, provides a far better correlation, showing the functional-anatomical structure of the visual cortex by projection in three planes (transverse, sagittal, coronar). CT, however, can not replace angiography in cases where arteriovenous malformations are suspected.
