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. Two examiners, masked to the automated perimetry re...
متن کاملMeasurement error of visual field tests in glaucoma.
AIM Psychophysical strategies designed for clinical visual field testing produce rapid estimates of threshold with relatively few stimulus presentations and so represent a trade-off between test quality and efficiency. The aim of this study was to determine the measurement error of a staircase algorithm similar to full threshold with standard automated perimetry (SAP) and frequency doubling per...

This article is dedicated to main information about visual field, monocular and binocular ranges of visual field including their defects. Visual field loss may occur to disease of the eye, optic nerve or brain. Typical changes are present at glaucoma and macular degeneration. Visual pathway is also mentioned. The basic medical examinations of visual fields are Amsler grid, kinetic and static pe...
متن کاملPredicting binocular visual field sensitivity from monocular visual field results.
PURPOSE To compare methods of predicting binocular visual field sensitivity of patients with glaucoma from monocular visual field data. METHODS Monocular and binocular visual fields were obtained for 111 patients with varying degrees of glaucomatous damage in one or both eyes, using the Humphrey 30-2 full-threshold procedure. Four binocular sensitivity prediction models were evaluated: BEST E...
