Your Humphrey Field Analyzer II has a number of options for using different parameters and
testing strategies. The first part of this section discusses standard and non-standard testing
parameters as well as the procedure to modify the parameters for specific patients.
The second portion of this section discusses Blue-Yellow
perimetry or SWAP (Short-Wavelength Automated
Perimetry) and SITA (Swedish Interactive Thresholding
Algorithm), two testing methods developed by Carl Zeiss
Meditec in cooperation with leading authorities.
This section answers these and other questions:
• What test parameters can I change during the test?
• Can I slow down the test for an elderly patient?
• What are SWAP and SITA?
• Why is the Size V stimulus used for Blue-Yellow testing?
• When can the SITA testing strategy be used?
