PURPOSE: To evaluate the usefulness of the SITA-Standard (SITA-S) strategy for perimetric threshold determination by Humphrey perimetry in patients with glaucoma. METHODS: Humphrey perimetry thresholds were measured using the central 30-2 program with the Full Threshold strategy and with the SITA-Standard strategy in 20 eyes of 20 patients with glaucoma. In half the patients, the Full Threshold strategy was used first, followed by the SITA-S strategy, and in the other half, the order of strategies was reversed. RESULTS: The time needed to complete the examination with the SITA-S strategy was 50% of that required to complete threshold measurement with the Full Threshold strategy. In each case, thresholds measured with the SITA-S strategy correlated closely with those measured using the Full Threshold strategy (r = 0.8824, p < 0.0001). On average, thresholds measured using the SITA-S strategy were significantly higher (1.01 ± 3.89 dB, p < 0.0001) than those measured using the Full Threshold strategy; 95.4% of measurements obtained using the SITA-S strategy were within ±8 dB of those measured using the Full Threshold strategy. The 'error' thresholds (4.6% of responses) were located on the steep slopes of deep scotomas. The SITA-S strategy detected absolute scotomas as well as the Full Threshold strategy. CONCLUSIONS: The SITA-S strategy is useful for measuring visual fields in eyes with glaucoma. LA: Japanese
