Introduction/Instrument Setup About Visual Fields The Humphrey Advantage Using This Guide Safety Precautions System Components 1-12 Additional Components 1-14 System Assembly 1-17 ® You are about to use the most advanced automated perimeter available, the Humphrey Field Analyzer II (HFA II). This introductory section covers general information about the HFA II, including a brief discussion of visual fields and a summary of important instrument features.
Page 10: About Visual Fields
INTRODUCTION / INSTRUMENT SETUP 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 11 INTRODUCTION / INSTRUMENT SETUP Normal versus The visual field normally extends more than 90° temporally, 60° nasally and superiorly, pathologic fields and about 70° inferiorly. That means a person can potentially perceive stimuli within this range while staring at a fixed point. Superior 60°...
Page 12 INTRODUCTION / INSTRUMENT SETUP A defect (or scotoma) is categorized as either relative or absolute. A relative defect is an area that has depressed vision or less than normal sensitivity; an absolute defect is an area where the perception of light is absent. The point at which the optic nerve enters the retina is referred to as the blind spot, and is an example of an absolute scotoma.

Page 76: Setting Test Parameters
TEST PARAMETERS AND STRATEGIES SETTING TEST PARAMETERS Test parameters are the testing conditions used during a test, e.g. stimulus size, test strategy, test speed, etc. While the majority of patients are best examined using “standard” parameters (or default parameters), you can alter the parameter settings for purposes of tailoring the test to meet particular patient needs.
Page 77 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 as the “standard” setting. It is distinguished from the others by the appearance of an asterisk (*) on the parameter button. If you want to return all settings to the standard mode, select RESET TO STANDARD.
Page 78: Test Strategies
TEST PARAMETERS AND STRATEGIES TEST STRATEGIES One of the most important test parameter settings is strategy. For both screening and threshold testing, the strategy 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.
Page 79 TEST PARAMETERS AND STRATEGIES Screening Parameter Description Parameters Settings Large Diamond The Large Diamond is located below the Central target and is useful for patients with central scotoma who cannot see either the Central fixation light or the Small Diamond. Bottom LED Some tests have points in the superior visual field that require a lower fixation light than the central...

Page 84: Sita ™ Testing
The SITA testing strategy represents a major advance over the methods currently in use. Carl Zeiss Meditec has developed 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 Humphrey Full Threshold standard algorithm.
Page 85 Teams at U.C. Davis, U.C. Berkeley, and U.C. San Diego began working together under the sponsorship of Carl Zeiss Meditec to resolve the differences in their approaches and to define an optimized common standard. They presented their recommendations to a larger group from North America and Europe for peer review, criticism, and finally, acceptance.
Page 86 4-12 TEST PARAMETERS AND STRATEGIES Patient selection for Blue-Yellow perimetry has been found to be appropriate for early glaucoma detection in: blue-yellow perimetry • ocular hypertensives • glaucoma suspects • glaucoma patients with mild to moderate field loss. While Blue-Yellow perimetry has the potential of becoming the primary perimetry method used in glaucoma management, we recommend that it be done as a complement to standard Humphrey white-on-white testing until more clinical experience has been gained.
Page 87 TEST PARAMETERS AND STRATEGIES 4-13 Room illumination should be off or at a very low level in order to preclude significant amounts of stray light from falling on the bowl and affecting Blue-Yellow test conditions. From the Start of Test screen select CHANGE PARAMETERS. Switch Blue-Yellow from Off to On and press SELECTION COMPLETE.

This section explores your options available during the test.
Page 92: 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.
Page 93 TESTING DEMO This feature runs a short practice test. Demo allows the patient to preview what is required during a visual field test. It also allows you to evaluate whether the patient understands your instructions and the use of the patient response button. Patient responses are not recorded during the Demo test.
Page 94: Monitoring And Maintaining The Patient's Eye Position
TESTING MONITORING AND MAINTAINING THE PATIENT’S EYE POSITION Video Eye Monitor All HFA II models feature a video eye monitor. This monitor, which is automatically visible on the Start of Test screen, enables you to view the patient’s test eye. Accurate placement of the eye is important.
Page 95 TESTING The gaze graph The gaze graph is a useful method for documenting movement of the patient’s test eye. A test starts with no markings on the gaze graph. As time progresses, the graph expands from the right, marking eye movement and blinks. Upward markings indicate that the test eye deviated from the fixation target at the time of stimulus presentation.
Page 96 TESTING It is possible in certain situations for the Head Tracking feature to “lose its place”. The most common reason for this is a sudden shift of the eye or reposition- ing of the head. A patient whose head does not move with the chin rest will cause Head Tracking to beep.
Page 97: Supplemental Testing
TESTING SUPPLEMENTAL TESTING Foveal Threshold and Gaze Track Initialization are performed before a test begins. They are called “supplemental tests”. Foveal Threshold The Foveal Threshold test measures the sensitivity of the central part of the macula, the fovea. Foveal threshold testing is the only available with threshold visual field tests. Whenever the Foveal Threshold parameter is turned ON, the Foveal Threshold test is the first supplemental test procedure.
Page 98 TESTING Gaze tracking initialization The advantages of Gaze Tracking were previously explained in this section. If gaze monitoring is active, the 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 an operator message.
Page 99 TESTING If Gaze Track Initialization is successful, press CONTINUE to begin testing. Note: It is important that the patient maintain the same position during gaze initializa- tion and testing. If Gaze Track Initialization is unsuccessful, press RE- TRY TO INITIALIZE GAZE. Refer to “Fixation Monitoring”...
Page 100: Test In Progress
TESTING 5-10 TEST IN PROGRESS You have several options while a test is in progress. PAUSE This button halts the test and allows the patient to rest. The patient can also pause the test by continuously holding down on the response button. Once in the pause mode, you may choose to resume the test, display the current test parameter settings, change the fixation monitoring system, change the test speed, or cancel the test.
Page 101 TESTING 5-11 Printing partial If a test is paused or cannot be run to completion, it may be printed by pressing the PRINT tests FUNCTIONS icon button. Paused tests may be resumed after printing and saved when completed. Partial tests cannot be saved in most cases. Full field tests may be saved at the completion of the central part of the visual field.
Page 102 TESTING 5-12 TURN OFF BLIND SPOT MONITOR Press this button to turn off the Heijl-Krakau method of Blind Spot Monitoring. If Gaze/Blind Spot had been chosen at the start of the test and gaze tracking is initialized, the gaze tracking will continue to monitor fixation while the blind spot monitor is turned off.
Page 103 TESTING 5-13 Tips for gaze tracking The keys to successful Gaze and Head Tracking are the same keys that make for successful and head tracking visual field testing. Make sure the patient’s chair has been moved close to the instrument. If available, remember to slide the instrument toward the patient so the patient can sit in a comfortable, upright position.

Test Reliability Factors Affecting Reliability Patient Compliance Patient Fixation Trial Lenses Evaluating Reliability Fixation Losses False Positive Errors False Negative Errors Fluctuation Values 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 110: 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 111: Patient Fixation
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 112: 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. Fixation losses When the fixation monitoring test parameter is set to blind spot (Heijl-Krakau) mode, proper fixation is checked by projecting 5% of stimuli at the presumed location of the physiological...
Page 113 False Negative Abnormally high results Gaze Graph Carl Zeiss Meditec Figure 6.1: Sample Printout Showing Poor Reliability. The example above indicates a very unreliable patient. A high number of fixation losses, false positive errors, and false negative errors have been recorded. Poor fixation is indicated by the gaze graph.
Page 114: False Negative Errors
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. The printout will show the total number of false negative errors followed by the total number of trials.

Page 118: Statpac Analysis & Printing Results
STATPAC ANALYSIS & PRINTING RESULTS INTRODUCTION TO STATPAC ANALYSIS The Humphrey Field Analyzer II’s statistical software, STATPAC, provides immediate expert system analysis of threshold visual field test results. With STATPAC you can analyze test results at the time of examination, store test results and analyze them at your convenience, or recall previously stored tests to analyze for comparative purposes.

STATPAC ANALYSIS & PRINTING RESULTS THRESHOLD TEST PRINTOUT FORMATS Until this point, the User’s Guide has focused on the use and operation of the HFA II. In attempting to explain the information provided on printouts, however, we must enter the realm of interpretation of field results.
Page 121 STATPAC ANALYSIS & PRINTING RESULTS The single field analysis The Single Field Analysis is based on the results of a single central threshold test. The top printout of the page presents patient data, test reliability indices, and the test results in the grayscale and numeric formats.
Page 122 STATPAC ANALYSIS & PRINTING RESULTS The glaucoma hemifield test On 24-2 and 30-2 tests taken using the SITA Standard, SITA Fast or Full Threshold strategies, the Glaucoma Hemifield Test (GHT) evaluates five zones in the superior field and compares these zones to their mirror image zones in the inferior field. The GHT evaluates the severity of disturbed points in each zone pair, relative to its normative database, and prints one of these messages: GHT WITHIN NORMAL LIMITS, OUTSIDE NORMAL LIMITS, or BORDERLINE.
Page 123 STATPAC ANALYSIS & PRINTING RESULTS Total deviation plots On the left in the lower half of the Single Field Analysis printout is a pair of plots, one above the other, labeled Total Deviation. The numeric values in the upper portion of these plots represent the difference in decibels (dB) between the patient’s test results and the age-corrected normal values at each tested point in the visual field.
Page 124 STATPAC ANALYSIS & PRINTING RESULTS PSD stands for Pattern Standard Deviation. PSD is a measurement of the degree to which the shape of the patient’s measured field departs from the normal, age-corrected reference field. A low PSD indicates a smooth hill of vision. A high PSD indicates an irregular hill and may be due either to variability in patient response or to actual field irregularities.

Page 139: Blue-Yellow Printout Formats
STATPAC ANALYSIS & PRINTING RESULTS 7-23 BLUE-YELLOW PRINTOUT FORMATS Blue-Yellow printouts use the same grayscale as White-on-White testing. The grayscale will look significantly darker with Blue-Yellow testing in most cases. This is because Blue-Yellow testing normally generates lower threshold values than does White-on-White testing. It is particularly important to pay most attention to the STATPAC probability plots rather than the traditional grayscale.
Page 140 7-24 STATPAC ANALYSIS & PRINTING RESULTS Glaucoma hemifield test Glaucoma Hemifield Test (GHT) results are available when the Full Threshold testing strategy is used.

Page 168: Introduction To Database Management
Because both hard and floppy disks store information magnetically, the information can be damaged by static electricity and strong magnets. Database management is not difficult and should not consume much time. Carl Zeiss Meditec strongly recommends that all HFA customers make extra copies of their patient database and setup configurations.
Page 169: Patient Database Protection Procedures
Creating alternate copies of your patient database is important, but can be a lengthy procedure. Therefore, Carl Zeiss Meditec recommends that you choose a schedule that suits your office, preferably one that does not interfere with patient care and testing. Whether you perform 25 visual field tests each week or five, every test worth saving (whether to floppy disk, hard disk, or both) is worthy of being protected by being maintained on alternate storage media.
Page 170 Caution: Although the HFA allows you to back up the entire contents of your hard drive to floppy disk (BACKUP to FLOPPY), Carl Zeiss Meditec does not recommend that you adopt this as your sole backup procedure. If, while restoring data, one floppy disk in the series is damaged, the entire set becomes unusable.
Page 171: Configuration Backup And Restore
DATABASE MANAGEMENT CONFIGURATION BACKUP AND RESTORE Custom test patterns, Main Menu button definitions, and System Setup choices can be backed up on a formatted floppy disk. This backup includes all changes made via the Alter Main Menu feature. It also includes settings in the System Setup and Additional Setup screens, including Personalized ID, printer choice, etc.

Page 173 DATABASE MANAGEMENT If you are sure that you have chosen the correct disk, press CONTINUE. Note: Even if you choose a blank, formatted disk, your HFA II will format it again to ensure the integrity of the disk. A pop-up window will display the message, “Floppy Successfully Formatted.”...
Page 174 DATABASE MANAGEMENT To restore configurations Restoring configurations will replace your existing configuration with those contained on a Configuration Backup floppy disk. See previous discussion, “Configuration Backup and Restore”. Note: If your office uses more than one HFA II, and you desire consistent configuration settings among all your instruments, you may use a single configuration backup disk to restore settings to all the other units.
Page 175 DATABASE MANAGEMENT Press RESTORE CONFIGURATION. Insert the appropriate Configuration Backup floppy disk. Press CONTINUE. The Main Menu and Custom test configurations will be restored. When restoration is complete, press OK. After a 15 second pause, your HFA II will automatically restart using the restored configuration.
Page 176: How To Handle Database Failures
9-10 DATABASE MANAGEMENT HOW TO HANDLE DATABASE FAILURES It is important to realize that the HFA II has built-in safeguards against loss or damage of valuable data. You see the evidence of this when, performing certain file functions, you see the following pop-up window.
Page 177 DATABASE MANAGEMENT 9-11 You will want to address the hard drive problem as soon as your schedule permits. The initial attempt to fix the database problem may not be successful, however. If that is the case, your next option is to use the rebuild utility (REBUILD HARD DRIVE DATABASE) found in System Setup (ADDITIONAL SETUP).
Page 178 9-12 DATABASE MANAGEMENT Hard drive failure: If you are faced with a hard drive failure, and you elect to attempt recovery immediately, FIX NOW option choose the FIX NOW option. This option should only be initiated if you have the time, and patients will not be inconvenienced.
Page 179 DATABASE MANAGEMENT 9-13 If recovery is successful and the FLOPPY ONLY option had never been engaged, the HFA II automatically completes the original function (before failure). If recovery is successful and the FLOPPY ONLY option had been engaged, the HFA II displays a reminder message.
Page 180 9-14 DATABASE MANAGEMENT Read the warning message. Select YES. Selecting NO returns you to Step 1. Continue saving test results to floppy disk until you have the time to engage the recovery program. Note: Each time you attempt to save data or try to use a function that involves the hard drive, the previous two screens will be displayed.
Page 181 DATABASE MANAGEMENT 9-15 If recovery is unsuccessful, a user message appears. Select OK. Go to next option: “Rebuild Hard Disk Database”. Hard drive failure: In the event the FIX NOW recovery attempts have failed, use the rebuild utility (REBUILD HARD REBUILD HARD DISK DISK DATABASE).

Page 185 The hard disk is disabled as a result of choosing SAVE TO FLOPPY ONLY. Caution: Carl Zeiss Meditec does NOT recommend a floppy disk backup of the entire database as your only method of data backup. If during restoration one of the disks is damaged, the entire set of disks becomes unusable.
Page 186: Merge Database
9-20 DATABASE MANAGEMENT MERGE DATABASE 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 magneto-optical or backup floppy disks.
Page 187: Cleanup Hard Disk Database
DATABASE MANAGEMENT 9-21 Insert the backup magneto-optical disk or first backup floppy disk, and select OK. A pop- up window with the phrase “Restoring from magneto-optical/floppy” and a progress indicator will appear. The HFA II is analyzing the disk to determine how long it will take to merge the two databases.
Page 188: Care And Handling Of Removable Storage Media
Having all patient data on all instruments also ensures that test results are safeguarded against accidental erasure or database problems with a different instrument. Carl Zeiss Meditec recommends the following method to maintain identical patient databases on multiple HFA IIs: 1.

Page 309 APPENDIX A A-21 Appendix G: How SITA Works / Acknowledgments To better explain how SITA works, we will use analogies. Think of perimetry testing as taking a patient’s case history. Think of SITA as an experienced doctor. Think of current perimetry strategies as student doctors. With these analogies in mind, we will describe how SITA reduces test time in the following four ways: 1.
Page 310 A-22 APPENDIX A APPENDIX G 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.

Over one-thousand subjects from around the world were recruited to participate for the multiple perimetry tests necessary to develop the STATPAC for SITA database.
