To investigate the efficiency and reliability of a new perimetry test algorithm, the results of two computerized static threshold perimetry strategies, namely a dynamic strategy (DS) and a tendency oriented program (TOP), were compared with the results of testing using the standard full threshold strategy. The authors examined 30 eyes of 30 individuals without ocular disease, and 27 eyes of 27 patients with glaucoma, using the full threshold strategy (4-2 dB), DS, and TOP of a modified Octopus 1-2-3 perimeter and program 32 X as the test grid pattern. They compared the efficiency (time required for presentation of the stimulus and obtaining test results), and the global indices, mean sensitivity (MS), and loss variance (LV), of the strategies. Compared to the normal full threshold strategy, the mean test time with DS was 47.7% less, and with TOP it was 82.0% less. With regard to global indices, the authors noted a tendency toward depression of mean retinal sensitivity using DS compared to the normal strategy. The results show DS to be considerably more efficient than TOP for detection of early glaucomatous defects, whereas TOP was found to be the most time-efficient.LA: Japanese
