The HFA II-
i
offers a variety of screening and threshold test patterns that meet most clinical needs.
Table 3.1 suggests which test strategies may be best suited
for specific disease categories. Table 3.2,
Table 3.3, and Table 3.4 describe each test pattern in order to assist you in choosing the one best
suited to the patient’s needs. Appendix (F), "Test Patterns" contains diagrams of all the available
test patterns.
Screening tests serve an important clinical function by quickly surveying the visual field and
flagging
areas that are highly suspect. They answer the question, “Is there a problem?” Abnormal test results
warrant additional threshold testing. See Table 3.2 for available Screening tests.
Threshold tests more precisely define the problem by calculating the actual sensitivity level at eac
h
test point. They uncover early depressions and subtle changes in retinal sensitivity. See Table 3.3 for
details about the various Threshold tests.
Specialty tests are specially designed scre
ening tests for specific purposes. See Table 3.4 for details
about the Specialty tests.
Models 740
i
, 745
i
and 750
i
allow you to create and store your own Custom test patterns. In
addition, the HFA II Model 750
i
offers Kinetic testing (optional on 740
i
and 745
i
). See Chapter (12),
"Custom Testing," and Chapter (13), "Kinetic Testing," for more information on these testing
options.
