Perimetric motion thresholds are elevated in glaucoma suspects and glaucoma patients

Description
Summary:The purpose of this study was to determine if a clinically feasible perimetric motion test utilizing random-dot kinematograms could identify glaucomatous visual field defects. Using a staircase procedure, an automated perimetric motion test and a larger foveally presented target were given to normal ( n = 30), glaucoma suspects ( n = 31) and primary open-angle glaucoma patients ( n = 19). Motion thresholds at specific locations throughout the whole visual field were significantly elevated in glaucoma patients ( P ≤ 0.001). Perimetric motion testing identified 84.2% of the primary open-angle glaucoma patients and 25.8% of the glaucoma suspects as abnormal. A larger foveal stimulus was unable to distinguish between the different subject groups ( P ≤ 0.185). Perimetric motion thresholds were significantly correlated with Humphrey standard visual field thresholds in the glaucoma and glaucoma-suspect patients ( P ≤ 0.0002).
