Humphrey Field Analyzer II- i printouts provide information important both in diagnosis and
continued care. They document a patient’s current visual field status as well as changes in sensitivity
over time. Coupled with Humphrey’s STATPAC software, HFA II-i printouts provide access to
sophisticated statistical analysis of visual field results. This chapter describes the standard HFA print
formats and how to generate printouts both immediately after testing and from stored files. After
reading this section you will be able to answer the following questions:
• How is the Glaucoma Hemifield Test (GHT) result determined?
• What is the difference between the Total Deviation and Pattern Deviation plots?
• How do I print an Overview printout?
• What are the parts of a Change Analysis box plot?
• What steps do I use to print a previously saved test?
Guided Progression Analysis (GPA) is an advanced analysis for visual fields that highlights
changes from baseline that are larger than the test-retest variability found in most
glaucoma patients. GPA is an optional module: It comes with STATPAC software but must
be licensed to be activated. See Chapter (8), "Guided Progression Analysis (GPA)," for
more information, including contact information to obtain a license or purchase the
software.
