High-pass resolution perimetry: Central-field neuroretinal correlates
Minimum angles of resolution (MAR) were measured at 0-10 deg horizontal eccentricity in three normal subjects, using high-pass spatial frequency filtered targets, at four different contrast levels. Results were correlated with recent data on human cone and ganglion cell separations in corresponding retinal locations. MARs and cone separations showed a close proportionality through the origin fo...
متن کاملCorrelation of Relative Dispersion Analysis and Other High Pass Resolution Perimetry Indices with Standard Threshold Perimetry
Purpose: Relative dispersion analysis (RDA), a new high pass resolution perimetry (HRP) index, appears to capture a novel aspect of visual field abnormality. The aim of this study was to evaluate the correlation of RDA and other HRP indices with the Humphrey perimeter parameters. Methods: Fifty-six eyes were randomly recruited from among patients at the authors’ clinic. Twenty-nine eyes were cl...
متن کامل1235 High-pass resolution perimetry vs static threshold perimetry in advanced primary open-angle glaucoma
PURPOSE: To compare Static Threshold Perimetry (Humphrey 30.2) with High-pass Resolution Perimetry (Ophthimus) for the assessment of Visual Field W.F.) defects in uatients with advanced glaucomatous damage. METHODS: Patient selection criteria: Primary Open-angle Glaucoma, advanced V.F. damage (MD > 5 dB) visual acuity > 20/70. previous experience in V.F. testing: 38 eyes were selected for the s...
متن کاملVariability of high-pass resolution perimetry in normals and patients with idiopathic intracranial hypertension.
High-pass resolution perimetry, or the "ring test," is a recently developed type of acuity perimetry. To determine its test-retest variability, we studied 10 normals and 10 patients with idiopathic intracranial hypertension (IIH) by testing both eyes four separate times. There was no increase in variability from the center out to 21 degrees of visual field eccentricity. However, there was a sig...
متن کاملHigh spatial resolution automated perimetry in glaucoma.
BACKGROUND Automated perimetry is of fundamental importance in assessing visual function in glaucoma. A technique was evaluated to perform high spatial resolution automated perimetry to allow a more detailed assessment of the luminance sensitivity in selected regions of the visual field than is possible with conventional perimetry. METHOD High spatial resolution perimetry was performed using ...
