Testing for glaucoma with frequency-doubling perimetry in normals, ocular hypertensives, and glaucoma patients.

摘要: Abstract Background. The aim of this study was to evaluate the diagnostic usefulness FDT perimeter protocol (C-20-5) in combination with a database system for analysis single test locations. Methods. One hundred seventy-three ocular hypertensive eyes, 116 "preperimetric" open-angle glaucoma eyes (glaucomatous optic disc atrophy, elevated intraocular pressure, no visual field defects standard white-on-white perimetry), 199 "perimetric" atrophy and defects), 151 control underwent screening conventional perimetry. Four repeated measurements were carried out 15 patients at 2-h intervals judge reproducibility all present strategy begins testing normal 5% probability level. If stimulus is not detected, further targets are presented. FDT-Viewfinder statistics software used case-wise recalculation missed localized levels correlation corresponding locations using Results. Analysis reveals that variation points can be considerable. However, numbers test-stimuli calculated globally or quadrants significantly correlated Octopus (Spearman rank P<0.001). Using predefined specificity 96% 11% 28.5% 86.9% have been classified glaucomatous an overall score consideration different cut-off right left eyes. Conclusion. Point-wise results helpful classification patient groups individual learning curve measurements. C-20-5 able detect considerable proportion patients.
