Diagnostic accuracy of confrontation visual field tests.
OBJECTIVE To determine the diagnostic accuracy of confrontation visual field testing and to compare the accuracy of confrontation tests both individually and in combination. METHODS Patients were prospectively recruited from ophthalmology clinics over a 6-month period. All patients underwent SITA-standard 24-2 Humphrey visual field analysis.

متن کاملHemispace-visual field interactions in visual extinction.
Visual extinction was studied in a patient with neglect from a right hemispheric lesion. Extinction occurred during double simultaneous stimulation within the same visual hemi-field (VHF). This finding suggests that interhemispheric rivalry is not a critical factor. During double simultaneous stimulation within the same VHF as well as with stimuli in different VHFs, the severity of extinction w...
متن کاملBromocriptine for visual field defects in prolactinomas.
The introduction of bromocriptine (2-brocergocryptine mesylate), a semi-synthetic ergot alkaloid, has revolutionised the treatment of the amenorrhoeagalactorrhoea syndrome due to excessive prolactin secretion (Thorner et. al., 1975). In a significant number of cases, this hyperprolactinaemia is caused by a radiologically obvious pituitary tumour (L'Hermite et. al., 1977; Bergh et al., 1978 a) w...
متن کاملRapid compensation of visual search strategy in patients with chronic visual field defects.
INTRODUCTION The aim of this study was to test the effect and specificity of a novel, compensatory eye movement training therapy designed to improve visual search performance in patients with homonymous visual field defects. METHODS Seven patients with chronic homonymous visual field defects and six healthy control subjects were tested. All subjects completed the single training period (300 t...
