PERIMETRIC MOTION THRESHOLDS ARE ELEVATED IN GLAUCOMA SUSPECTS AND GLAUCOMA PATIENTS

The purpose of this study was to determine if a clinically feasible pe rimetric motion test utilizing random-dot kinematograms could identify glaucomatous visual field defects. Using a staircase procedure, an au tomated 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 locatio ns throughout the whole visual field were significantly elevated in gl aucoma patients (P less than or equal to 0.001). Perimetric motion tes ting identified 84.2% of the primary open-angle glaucoma patients and 25.8% of the glaucoma suspects as abnormal. A larger foveal stimulus w as unable to distinguish between the different subject groups (P less than or equal to 0.185). Perimetric motion thresholds were significant ly correlated with Humphrey standard visual field thresholds in the gl aucoma and glaucoma-suspect patients (P less than or equal to 0.0002).
