Frequency Doubling Technology Perimetry Using a 24-2 Stimulus Presentation Pattern

To assess whether smaller targets and a 24-2 stimulus presentation pattern would improve the ability of frequency doubling technology (FDT) perimetry to detect and characterize early glaucomatous visual field loss.One hundred normal subjects between the ages of 20 and 85 participated in this study. In addition, 53 patients who either had early glaucomatous visual field loss (n = 23) or were high-risk glaucoma suspects with normal conventional...
