Recovery of visual-field defects after occipital lobe infarction: a perimetric study.
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 mean visual sensitivity ...
متن کاملHOMONYMOUS VISUAL FIELD DEFECTS Perimetric findings and corresponding neuro-imaging results
Selected neuro-ophthalmological cases demonstrate the diagnostic capabilities of adequate perimetric techniques: centripetally condensed stimulus arrangement and threshold-oriented, slightly supraliminal perimetry revealed even very small homonymous visual field defects, resulting from a small cortical lesion not exceeding the extent of the calcarine fissure. Subtotal bilateral superior altitud...
متن کاملA study on the natural history of scanning behaviour in patients with visual field defects after stroke
BACKGROUND A visual field defect (VFD) is a common consequence of stroke with a detrimental effect upon the survivors' functional ability and quality of life. The identification of effective treatments for VFD is a key priority relating to life post-stroke. Understanding the natural evolution of scanning compensation over time may have important ramifications for the development of efficacious ...
متن کاملVisual field defects and the prognosis of stroke patients.
Visual Field Defects and the Prognosis of Stroke Patients • The prognosis of stroke patients is related to the presence or absence of homonymous hemianopia at time of admission to a stroke center. Two hundred thirty-four patients were followed for an average of 15 months. In patients with nonhemorrhagic strokes in the middle cerebral artery territory the presence of a dense homonymous hemianopi...
متن کاملHomonymous visual field defects and stroke in an older population.
PURPOSE The objective of the present study was to describe the prevalence of homonymous visual field defects in a defined older urban population and associations with self-reported stroke. METHODS Homonymous visual field defects were assessed from screening automated visual field tests of both eyes in 3654 persons aged > or =49 years who were participating in the Blue Mountains Eye Study. Thi...
