Volume of visual field assessed with kinetic perimetry and its application to static perimetry
BACKGROUND The purpose of this study was to quantify the volume of the kinetic visual field with a single unit that accounts for visual field area and differential luminance sensitivity. METHODS Kinetic visual field perimetry was performed with a Goldmann perimeter using I4e, I3e, I2e, and I1e targets. The visual fields of 25 normal volunteers (17 women, eight men) of mean age 33.9 ± 10.1 (ra...
متن کاملVolume perimetry: measurement in depth of visual field loss.
PURPOSE Volume scotomas are three-dimensional regions of space that are not visible to the observer. Volume perimetry maps volume scotomas. Volume scotomas predicted from combining monocular visual fields assume known fixation locus (mainly foveal). However, fixation loci are not always known, especially with central field loss (CFL). Here we demonstrate methods for measuring and calculating vo...
متن کاملReliability of Volumetry and Perimetry to Assess Knee Volume.
CONTEXT The treatment of edema after a knee injury is usually 1 of the main objectives during rehabilitation. To assess the success of treatment, 2 methods are commonly used in clinical practice: volumetry and perimetry. OBJECTIVE To investigate the intra- and interassessor reliability of volumetry and perimetry to assess knee volume. DESIGN Cross-sectional. SETTING Laboratory. PARTICIP...
متن کاملComparison between Tendency-Oriented Perimetry (TOP) and octopus threshold perimetry.
OBJECTIVE To compare the results obtained by a new ultra-short automated perimetry test known as Tendency-Oriented Perimetry (TOP), which is an algorithm based on estimation of thresholds from information gathered from adjacent points with those obtained by a standard bracketing approach. TOP is designed to save up to 1/5 of the time taken by standard strategy by presenting each stimulus once o...
متن کاملComparative evaluation of oculokinetic perimetry and conventional perimetry in glaucoma.
Oculokinetic perimetry is a new method of visual field assessment in which the patient moves the eye around a central static target to look sequentially at an array of numbers. When fixation on a number is accompanied by disappearance of the central target, that number is deleted from a recording chart. Inversion of the recording chart gives a plot of the central visual field. In this study we ...
