Stroke sites and corresponding visual field deficits on perimetry. Top Row: day 8 T2-weighted MRI scan, axial slices (radiological convention, so images are flipped) through occipital cortex showing left acute occipital lesion and demonstrating midbrain lesion (traced or circled in white). Despite the fact that his midbrain lesion was right-sided, the patient had persistent left ptosis, with left lid artifact present on perimetry (white arrow). T2 images are shown as subacute ischemic lesions are difficult to see on T1 images. His right partial homonymous visual deficit can be seen on his perimetric visual field maps (black arrows). Note that perimetric tests were 90. visual field tests. Bottom row: repeat MRI at 6 months, axial T1-weighted slices through occipital lobes, revealed interval infarction in the right occipital pole (traced in white). Lid artifact still present from ptosis (white arrow), but perimetry revealed almost complete resolution of right homonymous deficit despite interval development of partial left inferior quadrantanopia (gray speckled arrow). LE, left eye; RE, right eye.
