A 72-year-old male with hypertension and an old-leftmiddle-cerebral-artery (MCA) stroke presented with symptoms of left-sided hemiparesis, left facial drop, leftsided neglect syndrome, and left-partial homonymous hemianopia. Symptoms were suggestive of a right MCA infarct; however, advanced neuroimaging was inconclusive. Conventional diagnostic angiogram of the right internal carotid artery (IC...

We investigated single-word reading in normal subjects and patients with alexia following a left occipital infarct, using PET. The most posterior brain region to show a lateralized response was at the left occipitotemporal junction, in the inferior temporal gyrus. This region was activated when normal subjects, patients with hemianopic alexia and patients with an incomplete right homonymous hem...

There is experimental evidence of trans-synaptic retrograde degeneration of retinal ganglion cells following retrogeniculate visual pathway lesions in primate studies. Retinal nerve fibre loss in congenital homonymous hemianopia in humans is well recognized from clinical observation but the findings in acquired lesions have been controversial. Forty-eight persons were recruited and divided into...

Cortical blindness is rarely an ictal manifestation. We report the case of a man who developed transient cortical blindness followed by permanent visual deficits during repeated partial seizures. Intermittent visual impairment began at age 14 years. After he had the first generalized seizure at age 28 years, neurologic, ophthalmologic, angiographic, and brain computed tomographic (CT) examinati...

BACKGROUND To describe a rare presentation of vertebral artery dissection (VAD) as a small but congruous incomplete homonymous hemianopia demonstrating use of visual field testing in the diagnosis. CASE PRESENTATION A 30 year old woman had been unwell for 4 months with difficulty focusing, vertigo, dizziness and a feeling of falling to the right. A small but congruous right inferior homonymou...

We used a visual distance reproduction task (endpoint task) to evaluate horizontal space representation in two left brain damaged (LBD) and three right brain damaged (RBD) patients with contralateral homonymous hemianopia and no neglect. All patients were examined in the chronic phase of the stroke and were aware of their visual field defect. Along with contralesional deviation in the line bise...
