Abstract

We have experienced automated and computerized perimetry using a Humphrey Field Analyzer in our Glaucoma Services. To evaluate its clinical efficacy, we report the results of the Armaly central field screening test in comparison with those of central 30-2 threshold test of the Humphrey Field Analyzer. One hundred fortythree eyes of 83 cases of normotensives, ocular hypertensives and glaucoma patients with open-angle or narrow-angle were enrolled in this study. Fiftyfour out of 61 patients (88.5%) and 73 out of 81 eyes (90.1 %) with visual field defect were detected by the screening test of the Humphrey Field Analyzer. Eight out of 81 eyes (9.9%) with visual field defect detected by the screening test were confirmed as false positive. All points of false positive were solitary, which tended to occur more frequently on superior vusual field. False negative of 8 eyes (12.9%) detected by the screening test were confirmed by the threshold test. The point of false negative was more frequent on superior field and showed to locate more peripherally from the fixation point. There was no significant difference in either central sensitivity or age of the false ring.
