Objective: To assess the temporal course of homonymous visual-field defects due to occipital lobe infarction, by using automated perimetry. Methods: 32 patients with ischaemic infarction of the occipital lobe were studied prospectively, using a Humphrey Visual Field Analyser II. The visual field of each eye was divided into central, paracentral and peripheral zones.

The basiocciput forms the superior half of the clivus; the squamosa forms the interparietal and supraoccipital calvaria; and the exocciput forms the lateral margins of the foramen magnum, occipital condyles, and hypoglossal canals. Infarction of the occipital pole causes homonymous hemianopia, and release hallucinations occasionally occur in the region of the field defect.1,2 A 64-year-old woman developed acute right homonymous hemianopia with vivid hallucinations in the right visual field. She drew what she experienced, including colored pinwheels and lines at right angles (figure, A). Because light exacerbated the Ulegyria is a diagnosis used to describe a specific type of cortical scarring in the deep regions of the sulcus that leads to distortion of the gyri.Ulegyria is identified by its characteristic "mushroom-shaped" gyri, in which scarring causes shrinkage and atrophy in the deep sulcal regions while the surface gyri are spared. Key Words: occipital lobe, visual field defect, cerebrovascular accident, stroke, (A) MRI of the head without contrast revealed bilateral occipital infarcts.

Symptoms of posterior cerebral artery stroke include contralateral homonymous hemianopia (due to occipital infarction), hemisensory loss (due to thalamic infarction) and hemi-body pain (usually burning in nature and due to thalamic infarction) 3 .

The occipital branches of the posterior cerebral artery were examined in 31 human brains. The authors determined the origin, course, and region of supply of each occipital branch: the parieto-occipital, calcarine, posterior temporal, and common temporal arteries, as well as the lingual gyrus artery.

occipital infarct (Figure 1) in the PCA territory and a right frontal infarct. Cerebral angiography revealed a subtotal occlusion of the right ICA, with minimal antegrade blood flow and patent cervical and intra-cranial ICA on later films (Figure 2). A direct communication was present between the right ICA To clarify the clinical features and mechanism of infarction in the posterior cerebral artery territory, we investigated 35 consecutive patients who presented with homonymous visual field defects and occipital infarction documented by computed tomography.

Results: On MRI, a left occipital lesion with mild enhancement after gadolinium infusion on the T1-weighted image, bright signal with some mass effect on the T2-weighted image, and the diffusion-weighted imaging suggested a diagnosis of an acute infarct. With the use of the exponential image technique, the T2 hyperintense signal present on the diffusion study was almost completely eliminated, changing the diagnosis and treatment plan.
