Homonymous 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...
متن کاملQuantifying relative afferent pupillary defects using a Sbisa bar.
AIM To compare the Sbisa bar (Bagolini filter bar) with neutral density filters (NDF) in quantifying relative afferent pupillary defects (RAPD). METHODS 11 patients with a RAPD were graded and a neutral density filter bar was used to quantify the RAPD. This was repeated using the Sbisa bar. The Sbisa bar (Bagolini filter bar) is used by orthoptists to quantify density of suppression in amblyo...
متن کاملoccipital war trauma and visual field defects
seven cases of visual field defects, caused by wartrauma were seen at farabi eye hospital. none were referred by a neurologist. four patients had 20/20 visions with normal fundi. one had 12/20, in both eyes, with normal fundi. two patients presented fundus changes. the visual field defects were seen in all these seven patients. four had homonymous hemianopia, one had bilateral field restriction...
متن کاملPupillographic characteristics of simulated relative afferent pupillary defects.
Relative afferent pupillary defects were simulated in normal individuals by performing the alternating light test while dimming the light in front of one eye with neutral density filters. Pupillary responses were elicited using a binocular photostimulator and recorded using a binocular television pupillometer. In five subjects, four spatial variables of the pupillary response--contraction ampli...
متن کاملAssessment of unilateral afferent pupillary defects by pupillography.
A pupillographic technique, an adaptation of the swinging light test, is described for the measurement of unilateral afferent pupillary defects. In normal persons it yielded accurate, reproducible estimates of the magnitude of artificial afferent defects made with neutral filters of 1 to 4 log units density. In 15 studies on 8 patients with unilateral optic neuritis and 2 with unilateral compre...
