K-6
• One SITA Standard 30-2 test.
• One SITA Fast 30-2 test.
• One Full Threshold 30-2 test.
Visit #2:
The same three perimetry tests were repeated in the same order, under conditions identical to those
of Visit #1.
Visit #3
Two perimetry tests:
• One half of subjects: • One half of subjects:
• One SITA Standard 10-2 test. • One SITA Standard 60-4 test.
• One SITA Fast 10-2 test. • One SITA Fast 60-4 test.
Note: The SITA Standard and SITA Fast 24-2 databases were derived from the data collected with
the 30-2 SITA Standard and SITA Fast threshold tests. Also, the 60-4 results were never
commercialized as a normative database.
SITA-SWAP:
There were two separate visits scheduled to complete the visual field testing. The first visit consisted
of both eyes being tested with the SITA-SWAP 24-2 threshold test. Both eyes were then tested in the
same order with the SITA Standard 24-2 threshold test. The pair of SITA-SWAP tests were always run
first. The eye tested first was randomized between subjects. Prior to performing each SITA-SWAP
test, the subject adapted to the yellow light of the bowl for a minimum of three minutes. There was
a minimum rest period of five minutes between all tests. The second visit was identical to the initial
visit in order of testing and number of tests.
GPA:
Only one eye was tested. Three visual field tests were performed at each session: one SITA Standard 30-2
test, one SITA Fast 30-2 test and one Full Threshold 30-2 test. A rest period of 15 minutes was required
between each test. The test order was the same for each visit and was randomized between subjects.
Database Demographics
The SITA normative databases (SITA Standard and SITA Fast) were developed utilizing 422 subjects
(ages 17-89). The mean age of these subjects was 53 years. The gender distribution was 44% male
and 56% female. Information on subject ethnicity was not collected as part of this database
collection. However, data was collected from centers in Asia, North America and Europe.
The SITA-SWAP normative database was developed utilizing 382 eyes of 194 subjects (ages 18-80).
The mean age of these subjects was 45 years. The gender distribution was 48% male and 52%
female. Ethnicity information was collected in this study. The ethnicity breakdown of the SITA-SWAP
database is as follows: 74% Caucasian, 8% Asian, 7% African-American, 5% Hispanic, 3% Indian
and 3% other ethnicities.
The GPA database was developed utilizing 363 subjects (ages 16-89). The mean age of these subjects
was 66 years. The gender distribution was 54% male and 46% female. Information on subject
