Comparison 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 ...
متن کاملClinical comparison of frequency doubling technology perimetry and Humphrey perimetry.
AIM To determine the number of missed points on frequency doubling technology (FDT) perimetry that optimise the sensitivity and specificity of the test and to determine the topographical accuracy of the test in a clinical setting. METHODS In a prospective study, the perimetric data from 99 patients who underwent both FDT perimetry in the screening mode and Humphrey 24-2 (H24-2) were used to d...
متن کاملComparison between Threshold Pupil Perimetry and Suprathreshold Pupil Perimetry
Purpose: Pupil perimetry has so far been performed by the two following methods: suprathreshold perimetry during which the amplitude or ratio of pupil constriction is determined, and threshold perimetry during which the threshold of pupil reaction is determined. The authors compared the values obtained with these two methods using the modified Octopus 1-2-3. Subjects and methods: Pupil perimetr...
متن کامل2004 : Flash / No - Flash
In this paper, we formulate the problem of natural image matting as one of solving Poisson equations with the matte gradient field. Our approach, which we call Poisson matting, has the following advantages. First, the matte is directly reconstructed from a continuous matte gradient field by solving Poisson equations using boundary information from a user-supplied trimap. Second, by interactivel...
