GLOSSARY 211

Short-term Fluctuation: The testre test (the intra test) variability of the threshold sensitivity values obtained on repeat testing within the same testing session, representing measurement error, SF is expressed as the standard deviation of distribution of repeat values obtained on replicate testing at a location of visual field.

SWAP: Short Wave length Automated Perimetry: Test that isolates the blue-sensitive portion of the visual system for testing, also known as blue-yellow perimetry.

Single Field Analysis: Basic STATPAC display of the results of a single field examination, showing threshold sensitivity values, reliability parameters, global indices and the statistical calculations to compare the results with the range of values expected from the eyes with no ocular disease.

STATPAC: Trademark for Humphrey software that performs a series of statistical calculations on the visual field results, with displays that include single field analysis, change analysis, glaucoma change probability and overview printouts.

SITA: Swedish Interactive Thresholding Algorithm: Recently available strategy to measure the threshold sensitivity and reliability parameters efficiently, to achieve optimal measurements with minimal time.

Total Deviation Value and Probability Maps: The total deviation decibel values are the difference between the measured threshold sensitivity and age corrected normal sensitivity at each location. The total deviation probability map highlights locations where deviation exceeds those found in fewer than 5%, 2%, 1% or 0.5% of normal.
