• We describe our initial clinical trials comparing the Fieldmaster automated visual field plotter (Synemed, Inc) with Goldmann kinetic perimetry performed by highly skilled perimetrists. The Fieldmaster utilizes a quick, randomized test procedure referred to as "suprathreshold static perimetry." The calibration and stimulus control features of the Fieldmaster have made it possible to derive approximate Goldmann-equivalent stimulus values and provide accurate, reproducible test conditions. Evaluation of 105 eyes (61 with defects, 44 normal) revealed a 98.5% detection rate and a 4% false alarm rate for the Fieldmaster in comparison with Goldmann kinetic perimetry. Based on these results, the Fieldmaster appears to have great potential value as a quantitative visual field screening device for the detection of visual field defects.
