Page 25: About Visual Fields
Introduction & Instrument Setup 1-17 About Visual Fields When asked to assess one’s own vision, the average person often will confidently reply, “I see 20/20”, “20/100” or whatever the result of their visual acuity test. Fortunately, doctors appreciate the complexities involved in evaluating visual function and rely on an extensive and varied battery of diagnostic tests and instruments as part of the ocular examination.
Page 26 Introduction & Instrument Setup 1-18 Normal Versus Pathologic Fields The visual field normally extends more than 90 temporally, 60 nasally and superiorly, and about º º inferiorly. That means a person can potentially perceive stimuli within this range while staring at º...
Page 27 Introduction & Instrument Setup 1-19 Some defect patterns are characteristic of certain diseases, a fact which makes visual field testing a valuable part of the diagnostic process. Furthermore, by having patients repeat the same tests at later dates, practitioners gain insight into the progression of the disease and the effectiveness of treatment.

Note that during testing, you can change only test speed and fixation monitoring.
Page 103 Test Parameters and Strategies Select the parameter setting. The current setting is highlighted. Repeat steps 1-2 for other parameters, then press SELECTION COMPLETE. Standard Parameters One setting for each parameter has been designated by design as the default setting. It is distinguished from the others by the appearance of an asterisk (*) on the parameter button.
Page 104: Test Strategies
Test Parameters and Strategies Test Strategies One of the most important test parameter settings is test strategy. For both screening and threshold testing, the strategy you use can affect the total test time and the precision to which the measurements are made. The strategy also dictates whether screening test results are displayed as qualitative (symbols) or quantitative (decibels) information.

They tie-up staff and tire out patients, thus decreasing test reliability. The SITA testing strategy is a major advance over the previous methods used. Carl Zeiss Meditec developed the two separate SITA testing strategies with two separate goals: 1. SITA Standard: The goal was to design a perimetric thresholding method which collects twice as much information per unit time as the original Humphrey Full Threshold standard algorithm.

Page 112: Start Test Options
Testing Start Test Options After you have chosen a test, specified which eye is to be tested, and entered the patient data, you will arrive at the Start of Test screen. From this screen you can start the test, display a list of all current parameters, change the parameter settings, and change the test eye.

Testing END DEMO, the pop-up window will disappear after one minute. The test will begin, immediately after the pop-up window disappears. Note: The Demo test runs only after the Foveal Threshold is determined and Gaze Tracking initialization is complete (if utilizing either of these features). Test Other Eye This button allows you to switch to the Start of Test screen for the other eye.
Page 114 Testing The three controls on the video eye monitor are: a plus sign (+) to brighten the image, a minus sign (-) to dim the image, and an OFF button to turn off the eye monitor display. To re-display the monitor, press the upper-left EYE button.
Page 115 Testing Downward markings indicate that the gaze system could not locate the patient’s gaze: small downward markings indicate that the system was unable to detect gaze direction; large markings indicate that the patient blinked while the stimulus was being presented. Minimal deviation of the markings (depicted as a horizontal line) indicates excellent fixation.
Page 116 Testing Vertex Monitor (Model 750 The Vertex Monitor will beep and display a message on the touch screen if the patient backs away more than 7 mm from his or her original position. This helps to eliminate the trial lens as a source of visual field defects.
Page 117: Supplemental Testing
Testing Supplemental Testing If selected, the HFA II- performs Foveal Threshold and Gaze Tracking initialization. They are called “supplemental tests.” These optional procedures are run prior to the start of the standard testing. Foveal Threshold The Foveal Threshold test measures the sensitivity of the central part of the macula, the fovea. Foveal threshold testing is only available with threshold visual field tests.
Page 118 Testing Gaze Tracking Initialization The advantages of Gaze Tracking were explained earlier in this chapter. If gaze monitoring is active, Gaze Tracking initialization will occur before the testing begins. From the appropriate testing screen, press the START button. When Gaze Monitoring is engaged, you will automatically get the displayed operator message. Position the patient so that the patient’s test eye is located in the center of the video eye monitor (within the small, central box).

Page 131: Test Reliability
Test Reliability (6) Test Reliability Factors Affecting Reliability Patient Compliance Patient Fixation Trial Lenses Evaluating Reliability Fixation Losses False Positive Errors False Negative Errors Visual field testing represents a team effort between the perimetrist and the patient. Success, as measured by reliable test results, is best attained by taking the necessary steps and precautions to help the patient take the test.
Page 132: Factors Affecting Reliability
Test Reliability Factors Affecting Reliability Patient Compliance The importance of the perimetrist reigns above all other factors affecting test reliability. This was true before the advent of automation and still proves to be true with computerized perimetry. The “human factor,” that is, the interaction between the perimetrist and the patient, cannot be overlooked when discussing test reliability.
Page 133 Test Reliability Patient Fixation Improper or erratic fixation may make test results meaningless. The perimetrist can play an important role by emphasizing fixation while explaining the test procedure. Tips for improving patient fixation: • Choose a fixation target that is appropriate for the patient. When you tell the patient to look at the yellow fixation light, verify that they can see the light by asking, “Do you see the yellow light? Is it clear?”.
Page 134: Evaluating Reliability
Test Reliability Evaluating Reliability Even with the most careful perimetric technique, sometimes test results are unreliable. To assist with evaluating reliability, the HFA II- offers several tools that measure accuracy and consistency. “Catch trials” are special stimuli (or lack of) which are used for monitoring. When the patient exceeds a set limit, a warning will display on the HFA screen and print on all types of printouts.
Page 135 Test Reliability In addition to a high false positive finding, trigger happy patients often show threshold results that are abnormally high. An example of this phenomenon is shown in Figure 6.1. Any individual point result of 40 dB or greater indicates a hypersensitive result which can only be due to patient overreaction or guessing when pressing the patient response button.
Page 136 Test Reliability False Negative Errors Occasionally during a test, a stimulus is repeated at a particular location and at a level much brighter than has already been seen. If the patient does not respond to this trial stimulus, a false negative error is recorded.

Guided Progression Analysis (GPA) Introduction to GPA Guided Progression Analysis (GPA) is a software package for the Humphrey Field Analyzer that is designed to help practitioners identify and quantify statistically significant progressive visual field loss in glaucoma patients. The software is designed for use with SITA Standard, SITA Fast and Full Threshold exams, but not SITA-SWAP exams.
Page 161 Guided Progression Analysis (GPA) GPA Was Clinically Developed GPA relies on detailed empirical knowledge of the threshold visual field variability that typically is found in everyday glaucoma patients. Two tests are averaged to establish a Baseline, and up to fourteen (14) Follow-up tests may be compared to the Baseline. Those fields that repeatedly and consistently show changes exceeding what is known to represent the expected range of test-retest variability are identified as having possible or likely progressive visual field loss.

SWAP differs from standard automated static perimetry in that blue light is used as the stimulus, and yellow light is used for the background illumination.
Page 196 Short-Wavelength Automated Perimetry (SWAP) How SWAP Works SWAP isolates and measures Blue-Yellow ganglion cell function. The carefully chosen bright yellow background desensitizes the green and red cones, while having little effect on blue cone function. The narrow-band 440 nanometer blue stimulus falls right on the peak sensitivity of blue cones. In addition, the larger Size V stimulus is used to help expand the dynamic range of the procedure.

The stimulus may initially appear as a deep blue light projected against the yellow bowl.
Page 198 Short-Wavelength Automated Perimetry (SWAP) For the Blue-Yellow field, select ON (Figure 9.1) in the drop-down box to turn on SWAP testing. When you turn on Blue-Yellow testing, the following changes occur automatically: •The Test Strategy changes to SITA-SWAP. •The Stimulus Size and Blind Spot Check Size change to Size V. •The Stimulus Color changes to Blue.
Page 199 Short-Wavelength Automated Perimetry (SWAP) Locate the visor handle that is located just below the forehead rest (see Figure 9.3). Slide the handle toward the back of the bowl (away from the patient). SLIDE VISOR HANDLE AWAY FROM YOU Figure 9.3 Extending the Blue-Yellow Visor Prior to Testing Note: The visor helps shield the patient’s eyes from the glare produced by the yellow bowl-illumination lamp.
Page 200 Short-Wavelength Automated Perimetry (SWAP) At the conclusion of SWAP testing, slide the visor back into the forehead rest. See Figure 9.4. A message will remind you to replace the visor beneath the forehead rest. Move the visor handle toward you (away from the test bowl). If the visor is not retracted, stimuli in the superior visual field may not be seen beyond 35 degrees during white-on-white testing.
Page 201 Short-Wavelength Automated Perimetry (SWAP) 4. As with white-on-white perimetry, we recommend that you confirm any abnormal findings before making a diagnosis that is based on the visual field results. Patients often exhibit a “learning effect” and may be better prepared for the SITA-SWAP testing routine on a second visit.
Page 202: Printing Out Sita-Swap Results
Short-Wavelength Automated Perimetry (SWAP) Printing Out SITA-SWAP Results The results of a SITA-SWAP test print in the Single Field Analysis (SFA) printout style (Figure 9.5). All of the traditional STATPAC features are available to review, including the Glaucoma Hemifield Test (GHT).
Page 203 Short-Wavelength Automated Perimetry (SWAP) Note: It is particularly important to pay more attention to the STATPAC probability plots than to the traditional grayscale plots. This is because reviewing the SWAP grayscale images using traditional white-on-white rules may lead to a misinterpretation of the SITA-SWAP test results. Note: SITA-SWAP test results and white-on-white test results cannot be printed on the same Overview printout.

Short-Wavelength Automated Perimetry (SWAP) 9-10 SITA-SWAP Case Studies The following examples illustrate various aspects of SITA-SWAP analyses. Case 1: Classic Nasal Step Figure 9.6 Nasal Step Seen in SITA-SWAP Printout In this example, you can see a significant nasal step and arcuate scotoma in the superior visual field of this patient's right eye on the SITA-SWAP printout.
Page 205 Short-Wavelength Automated Perimetry (SWAP) 9-11 Case 2: Comparing a SITA-SWAP Test with Standard White-on-White Testing Figure 9.7a Glaucomatous Visual Field Defect Discovered with SITA-SWAP In this case, an early paracentral visual field defect is seen with SITA-SWAP in the superior hemifield of the patient's right eye.
Page 206 Short-Wavelength Automated Perimetry (SWAP) 9-12 Case 2: (Continued) Figure 9.7b Standard White-on-White Results for the SITA-SWAP Patient Shown in Figure 9.7a This is the standard white-on-white visual field printout for this patient as discussed on the opposite page. Here the GHT indicates the visual field is “Within Normal Limits” while the SITA-SWAP indicates “Outside Normal Limits”.
Page 207 Short-Wavelength Automated Perimetry (SWAP) 9-13 Case 3: Effect of an Intra-Ocular Lens on SITA-SWAP Results Case 3 Figure 9.8 Effect of an IOL on Probability Plots and MD in Patient with Early Glaucoma This patient had cataract surgery and has an intra-ocular lens (IOL) in place of the crystalline lens. Because the SITA-SWAP database contains normal subjects that had various degrees of lenticular change in this age group, the patient has a mean deviation (MD) that is much higher than the norm.

Page 246 Database Management 11-12 Hard Drive Failure: FIX NOW Option If you are faced with a hard drive failure, and you elect to attempt recovery immediately, choose the FIX NOW option. This option should be initiated only if you have the time, and patients will not be inconvenienced.
Page 247 Database Management 11-13 If recovery is successful and the USB ONLY option had never been engaged, the HFA II- automatically completes the original function (before failure). If recovery is successful and the USB ONLY option had been engaged, the HFA II- displays a reminder message.
Page 248 Database Management 11-14 Hard Drive Failure: USB ONLY Option This option is only an interim measure, to be used in the event of a hard drive failure. It is designed to allow you to continue testing patients, and save patient and test data to a USB storage device until you can attend to the hard drive problem.
Page 249 Database Management 11-15 Select the desired USB storage device by pressing the button with its device name. Continue saving test results to the USB storage device until you have the time to engage the recovery program.

Page 255 Database Management 11-21 CAUTION: Carl Zeiss Meditec does NOT recommend that your only method of data protection is backing up the entire database to a single USB storage device. It is safest to have several sets of backups stored on different USB storage devices and to rotate them on a regular basis.
Page 256: Merging Databases
Database Management 11-22 Merging Databases The Merge Database function is designed to add tests from a backup source to the tests on the hard disk database (the destination). One disadvantage of the Restore Database function is that it erases all the patient tests on the hard disk and replaces them with the patient tests from the backup source.

Special Mapping is not available for testing done in the Automatic mode. Special Mapping provides you with a number of additional testing options which are described on the following pages: •...
Page 304 Kinetic Testing 13-28 Scotoma Mapping The Scotoma Mapping feature allows you to measure the size of a scotoma through the testing of multiple kinetic meridians. A point within the scotoma is located. When activated, the Scotoma Map feature sends the stimulus outward from the central point (a fixed number of times) to outline the boundaries of the scotoma.
Page 305 Kinetic Testing 13-29 The easiest way to locate the central point is to use the Cursor method. Move the cursor with the glidepad or finger on the touch screen to the desired location. In this example, the cursor is positioned to run the Scotoma Map from a point centered at Meridian: 200 and Radius: 15.
Page 306 Kinetic Testing 13-30 Note: The Humphrey Field Analyzer II- does not monitor the patient’s fixation automatically during kinetic perimetry. For reliable test results, it is imperative that you constantly monitor fixation with the video eye monitor. Note: The HFA II- will automatically map the scotoma according to the test parameters that you have chosen.

Page 541: K) Sita Normative And Gpa Databases
SITA Normative and GPA Databases (K) SITA Normative and GPA Databases How SITA Works Normative and GPA Database Collection and Demographics Acknowledgements How SITA Works To better explain how SITA works, we will use analogies. Think of perimetry testing as taking a patient’s case history.
Page 542 SITA Normative and GPA Databases The original Humphrey Full Threshold testing algorithm measured patient response time and made small adjustments to test pacing. SITA takes this idea much further using patented timing techniques. It is extraordinarily responsive to patient reaction times. One way to think about SITA is that the patient runs the perimeter, rather than the reverse.
Page 543: Normative And Gpa Database Collection And Demographics
SITA Normative and GPA Databases Normative and GPA Database Collection and Demographics Introduction The Humphrey Field Analyzer contains multiple normative databases that provide data for statistical comparison of how your patient's visual field results compare to an age-matched population. SITA Standard threshold test results are compared to one normative database, SITA Fast results to another.
Page 544 SITA Normative and GPA Databases SITA-SWAP Database The SITA-SWAP normative database was collected at a separate time and at different sites than the SITA and GPA databases. Four centers contributed normal data in this prospective, non-randomized, multi-center study. SITA-SWAP 24-2 threshold visual field test results were collected from healthy subjects aged 18 to 80.
Page 545: Data Collection
SITA Normative and GPA Databases GPA Database The GPA database consists of data from subjects that had been previously diagnosed with glaucoma. Results from nine centers were incorporated into the GPA database. Ages ranged from 16 to 89. Each subject was tested four times: once a week over a four-week period. Because the retest period was short, variability was expected to be due to inter-test variation and not progression of the disease.
Page 546 SITA Normative and GPA Databases • 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.
Page 547 SITA Normative and GPA Databases ethnicity was not collected as part of this database collection. However, data was collected from centers in Asia, North America and Europe. For the GPA short-term reproducibility dataset, the age distribution was determined by the prevalence of glaucoma in the test population. Only 30 subjects were younger than 50 years.

Reference to Older Test Strategies (L) Reference to Older Test Strategies Introduction The SITA Standard and SITA Fast testing strategies have replaced the Full Threshold and FastPac testing strategies for most threshold testing. In addition, SITA-SWAP is replacing the Full Threshold and FastPac strategies for testing SWAP visual fields due to the much shorter test times available when utilizing SITA-SWAP.

Page 553 Reference to Older Test Strategies The Glaucoma Change Probability Analysis Printout The Glaucoma Change Probability Analysis (GCP) is only available when you use the Full Threshold strategy. This analysis is based on visual field change, using the derived total deviation values. The newer Guided Progression Analysis (GPA) uses pattern deviation values and works with the SITA test strategies.

Page 555 Reference to Older Test Strategies Figure L.3 The Glaucoma Change Probability – Follow Up The glaucoma change probability printout (Figure L.2 Figure L.3) includes the patient information that appears on other STATPAC printouts. Two data presentations (graytone and total deviation plot) for the Baseline tests are printed on the upper left section of the printout. A plot of the Mean Deviation (MD) for each test plus the linear regression analysis of mean deviation, which is discussed below, occupy the upper right section of the printout.

Just above them is printed a message indicating whether the results of the glaucoma hemifield test (GHT) were within normal limits, outside normal limits, or borderline. The mean deviation from normal for this test is printed between the graytone and the total deviation plot.
Page 557 Reference to Older Test Strategies Additional Notes on SWAP Perimetry Although Carl Zeiss Meditec’s SWAP testing is available for screening tests in addition to threshold tests, research studies dealing with SWAP have involved threshold testing exclusively. Because screening strategies have been optimized for white testing, you may find an increased number of screening fields to appear abnormal.
