Sensitivity and specificity of the swedish interactive threshold algorithm for glaucomatous visual field defects1 1None of the authors has a commercial interest in Humphrey Systems.

To determine the sensitivity and specificity of two new visual field algorithms in detecting glaucomatous visual field defects: (1) Swedish interactive threshold algorithm (SITA) standard and (2) SITA fast.Prospective observational case series.Ninety normal subjects and 82 glaucoma patients.Central 30 degrees fields were performed with the Humphrey visual field analyzer 30-2 program (Humphrey Systems, Dublin, CA) using full threshold, SITA...
