There are differences in the shape and depth of the ipsilateral and the contralateral field defects not previously reported. These findings demonstrate that certain fibers from the ipsilateral eye travel more anteriorly and laterally in Meyer's loop, and support the hypothesis that visual field defects due to anterior retrogeniculate lesions are relatively incongruous because of anatomic differences in the afferent pathways. Automated perimetry is a sensitive method of evaluating and quantifying visual field defects.

We present a patient with aphasia of several days' duration that was secondary to spontaneous partial status epilepticus arising from the left basal temporal region. Evidence from MRI, EEG, and PET confirmed the origin of the seizures in the basal temporal area. Both the seizure discharges and the aphasia resolved after antiepileptic therapy. This case, to our knowledge, is the first documented example of epileptic aphasia secondary to spontaneous partial status epilepticus originating from the basal temporal area.
