If your patient comes in with head trauma and you preform a visual field.
Keep in mind the following.
– “Pie in the sky” visual field = temporal lobe lesion
– “Pie on the floor” visual field = parietal lobe lesion
– Anytime the lesion is in both eyes think post chiasmal.
– Also remember a lesion to the left side of the head is likely to give a right visual field defect and vice versa.
