摘　　要：AIM:To compare visual field defects using the Swedish Interactive Thresholding Algorithm(SITA)Fast strategy with SITA Faster strategy,a newly developed time-saving threshold visual field strategy.METHODS:Ninety-three participants(60 glaucoma patients and 33 normal controls)were enrolled.One eye from each participant was selected randomly for the study.SITA Fast and SITA Faster were performed using the 24-2 default mode for each test.The differences of visual field defects between the two strategies were compared using the test duration,false-positive response errors,mean deviation(MD),visual field index(VFI)and the numbers of depressed test points at the significant levels of P<5%,<2%,<1%,and<0.5%in probability plots.The correlation between strategies was analyzed.The agreement between strategies was acquired by Bland-Altman analysis.RESULTS:Mean test durations were 246.0±60.9 s for SITA Fast,and 156.3±46.3 s for SITA Faster(P<0.001).The test duration of SITA Faster was 36.5%shorter than SITA Fast.The MD,VFI and numbers of depressed points at P<5%,<2%,<1%,and<0.5%in probability plots showed no statistically significant difference between two strategies(P>0.05).Correlation analysis showed a high correlation for MD(r=0.986,P<0.001)and VFI(r=0.986,P<0.001)between the two strategies.Bland-Altman analysis showed great agreement between the two strategies.CONCLUSION:SITA Faster,which saves considerable test time,has a great test quality comparing to SITA Fast,but may be not directly interchangeable.
