PURPOSE: To compare two fast threshold strategies of visual field assessment; SITA fast (HSF) and tendency orientated perimetry (TOP), in detecting visual field loss in patients with glaucoma. METHODS: Seventy-six glaucoma, ocular hypertensive and normal patients had HSF and TOP performed in random order. Quantitative comparisons for the global visual field indices B mean deviation and defect (MD) for HSF and TOP, and pattern standard deviation (PSD) for HSF and loss variance (LV) for TOP B were made using correlation coefficients. Humphrey global parameters were converted to Octopus equivalents, and method comparison analysis was used to determine agreement between the two strategies. Test duration times were compared using the t test. Sensitivity and specificity for these two algorithms were determined according to predetermined criteria. RESULTS: High correlation coefficient values were obtained for MD measurements between HSF and TOP (r = -0.89, p
