Performance of efficient test procedures for frequency-doubling technology perimetry in normal and glaucomatous eyes

Abstract

PURPOSE. To validate the clinical performance of two new efficient threshold-estimation procedures for frequency-doubling technology (FDT) perimetry in both visually normal individuals and patients with glaucomatous visual field loss. METHODS. Forty-one normal subjects (mean age, 48.3 ± 11.6 years) and 50 patients with glaucomatous visual field loss (mean age, 72.7 ± 10.0 years) were tested. Some of these participants were retested within a 3-month period. FDT perimetry was performed on a color monitor driven by a visualstimulus-generating video board, with stimulus parameters designed to closely mimic those of the commercial FDT test. Visual field sensitivity was measured using three proced..
