Spatial and temporal processing of threshold data for detection of progressive glaucomatous visual field loss.
OBJECTIVE To evaluate the effect of spatial and temporal filtering of threshold visual field data on the ability of pointwise linear regression (PLR) to detect progressive glaucomatous visual field loss. METHODS Longitudinal visual field data (Full-Threshold Program 30-2 test point pattern) were simulated using a computer model of glaucomatous visual field progression. This approach permitted...
متن کاملSpatial pattern of glaucomatous visual field loss obtained with regionally condensed stimulus arrangements.
PURPOSE To assess the spatial distribution of glaucomatous visual field defects (VFDs) obtained with regionally condensed stimulus arrangements. METHODS Sixty-three eyes of 63 glaucoma subjects were examined with threshold-estimating automated static perimetry (full threshold 4-2-1 dB strategy with at least three reversals) on an automatic campimeter or a full-field perimeter. Stimuli were ad...
متن کاملThe Association of Glaucomatous Visual Field Loss and Balance
PURPOSE To relate balance measures to visual field (VF) damage from glaucoma. METHODS The OPAL kinematic system measured balance, as root mean square (RMS) sway, on 236 patients with suspect/diagnosed glaucoma. Balance was measured with feet shoulder width apart while standing on a firm/foam surface with eyes opened/closed (Instrumental Clinical Test of Sensory Integration and Balance [ICTSIB...
متن کاملMotion Perception Thresholds In Areas of Glaucomatous Visual Field Loss
This study examined whether one can differentiate between areas of known visual field loss and areas of known relative field sparing in eyes with primary open angle glaucoma using motion coherence thresholds. Two visual field locations from patients with primary open angle glaucoma (n = 14), which differed significantly in sensitivity, were selected for presentation of a motion stimulus. In the...
متن کاملMisleading statistical calculations in far-advanced glaucomatous visual field loss.
OBJECTIVE In this study, the capability of statistical analysis indices to characterize static automated visual fields (VFs) accurately in cases of far-advanced glaucoma was assessed. DESIGN Retrospective observational case series. PARTICIPANTS Sixteen eyes of 15 patients with end-stage glaucoma and evidence of collapse of VF statistical analysis indices were included in the study. METHOD...
