Instrument Overview

Thank you for purchasing the Humphrey Matrix® Visual Field Instrument, featuring
Frequency Doubling Technology.

The Humphrey Matrix Visual Field Instrument is an innovative, efficient, and compact
automated visual field testing instrument. Years of research and clinical trials of the
patented Frequency Doubling Technology have resulted in an instrument that provides
rapid, clinically validated and user-friendly visual field testing.

Frequency Doubling Technology (FDT)

Frequency Doubling Technology (FDT) isolates a subset of low redundancy, retinal ganglion
cell mechanisms in the magnocellular (M-cell) pathway. These M-cells have large diameter
fibers and comprise only 3% to 5% of all retinal ganglion cells. Damage to these cells, for
example in the glaucoma disease process, is detected by Frequency Doubling Technology.

Key features of the Humphrey Matrix:

• World-class clinical validation by leading researchers in the field

• Statistically significant correlation to the Humphrey Field Analyzer

• Extensive age-normative reference database

• Accurate & reliable supra-threshold screening tests in less than 1 minute per eye

• Full-threshold test results in five minutes per eye

• 24-2, 30-2, 10-2, N-30 and Macula FDT full-threshold tests

• FDT N-30 threshold and screening tests

• Video eye monitoring for patient alignment and fixation monitoring

• Easy to use; no special operator training or certification is needed

Intended Use

Humphrey Matrix is an AC-powered device intended to determine the extent of the
peripheral visual field of a patient. The device is intended to determine the amount of
visual field loss in a patient, which can then be used to diagnose/track the progression of
glaucoma and other eye diseases.

Patient Correction on page 5-11).

Indications for Use

Humphrey Matrix is an AC-powered device intended to determine the extent of the
peripheral visual field of a patient. The device is intended to determine the amount of
visual field loss in a patient, which can then be used to diagnose/track the progression of
glaucoma and other eye diseases.

Note: These perimetry results are an aid to interpretation, not a diagnosis. The doctor’s
judgment is still the most important element in determining the clinical significance of the
results, including considering the limitations of the statistical package.

Introduction

Matrix Instrument Software

Carl Zeiss Meditec pre-installs all software necessary to operate the Matrix System
instrument. Software updates with installation instructions may be provided on CD or on
the Matrix section of our website (

Data Storage

We recommend archiving data to a network file server. For non-networked environments,
an external USB hard drive can be used.

CAUTION: We do not recommend that you use optical disks for long-term data
storage or backup. Use should be limited to data transfer between systems. Take
care to protect these media from damage. We recommend you use hard plastic
cases when transporting and shipping these media. Optical disks are very
susceptible to scratches that could render them unreadable.

External Device Equipment

WARNING: To maintain patient safety, if the instrument is externally
connected to non-medical peripheral devices (i.e. printer, storage devices,
etc.), the complete system must continue to meet the applicable medical
requirements of IEC 60601-1 safety standard. This standard requires the
usage of an Isolation Transformer to power the non-medical peripheral
device if located within 1.5 m from the patient. If the peripheral device is
located outside the patient environment (beyond 1.5 m) and is connected
to the Matrix 800, a separation device must be used or there shall be no
metal to metal connection between the non-medical peripheral device and
the Matrix 800.

www.meditec.zeiss.com/matrix).

The person or the responsible organization connecting additional devices
or reconfiguring the system must evaluate the complete system to ensure
compliance to the applicable IEC 60601-1 requirements. The instrument
operator must not attempt to touch the patient and the peripheral device
simultaneously.

Failure to observe this warning could result in electrical shock to the
patient and/or examiner.

WARNING: Accessory equipment connected to the analog and digital
interfaces must be certified according to the respective IEC standards
(e.g., IEC 60950 for data processing equipment and IEC 60601-1 for medical
equipment).

Printers

Test Results and Reliability Measures

Screening Tests

All of the Humphrey Matrix visual field FDT screening tests are supra-threshold tests meaning
that they test at specific age-corrected contrast values determined by the normative database
probability levels. Select the probability levels to use for screening for general clinical use to
maximize sensitivity (-5 uses the 5% probability level) or for population based screening to
maximize specificity (-1 uses the 1% probability level). The screening test results consist of
probability plots of the tested locations for each eye and overall reliability measures along
with patient and test information. The test locations indicate the different probability levels
with different patterns, increasing in darkness with decreasing probability level.

Tests on page 6-8.

The N-30-5 (or N-30-1) FDT screening test is essentially the same 19-point rapid screening
test performed on the FDT Visual Field Instrument, except that moving the fixation target is
not required with the Humphrey Matrix. The same normative database is used for the N-30
tests in the FDT and Humphrey Matrix Visual Field Instruments so the tests are comparable
between the two instruments. Each test location is assigned one of four probability levels,
depending on the test selected. Each visual field location is tested until the patient
responds, or until all three probability levels are tested. The initial probability level is tested
twice if needed, followed by once at each of the other levels to complete the N-30
screening. As a result, the screening test time will increase for patients with eye disease.

See Sample

The 24-2-5 (or 24-2-1) FDT screening test is a screening version of the 24-2 full threshold
test. Each test location is assigned one of two probability levels, depending on the test
selected. Each visual field location is tested at a single probability level (pass/fail). Each
visual field location is tested until the patient responds or the location is tested twice at the
initial probability level to complete the 24-2 screening.

Threshold Tests

All the Humphrey Matrix visual field threshold tests are full threshold tests meaning that
they provide quantitative measures of the visual function at each location tested. The
threshold test results consist of a raw threshold plot (dB values), a gray scale plot (pattern
shading), total and pattern deviation plots (dB values), total and pattern deviation
probability plots (pattern shading), MD and PSD global indices (numeric with probability
values), overall reliability measures, along with patient and test information for each eye
tested. The probability plots indicate one of five possible probability levels with different
patterns, increasing in darkness with decreasing probability level. See

Sample Tests on page 6-8.

The N-30-F FDT full threshold test is essentially the same 19-point full threshold test
performed on the FDT Visual Field Instrument, except that moving the fixation target is not
required and the threshold algorithm has been optimized to reduce test time with the
Humphrey Matrix. The same normative database is used for the N-30 tests in the FDT and
Humphrey Matrix Visual Field Instruments so the tests are comparable between the two
instruments.

Test Results and Reliability Measures

For the N-30-F FDT full threshold test, the instrument utilizes a staircase threshold strategy
known as a Modified Binary Search (MOBS). The Humphrey Matrix utilizes a four-reversals
rule (N-30-F) for determining the threshold level. The range of possible threshold level
values for the raw data (patient threshold scores) is between 0 dB Maximum Contrast
(lowest patient sensitivity) and 56 dB Minimum Contrast (highest patient sensitivity). The

2048

formula used to calculate the dB values is

from 1 (minimum contrast) to 2048 (maximum contrast) and H is approximately 2. Note
that XX is displayed if the thr

eshold is not determined due to inconsistent patient
responses which do not meet the MOBS threshold criteria. The magnitude of the threshold
level values is directly correlated to the Field Analyzer values.

The 24-2, 30-2, 10-2 and Macula FDT full threshold tests are modeled after the Humphrey

Analyzer (HFA™) tests to provide visual field test results that are familiar. The FDT test

Field
results for the threshold tests correlate with the HFA results, but they are not directly
comparable. The FDT tests use a large (~270 subjects for each eye) age normative FDT
database. The FDT full threshold tests use a maximum likelihood threshold strategy known
as ZEST (Zippy Estimate of Sequential Testing) to provide accurate threshold results as
quickly as possible. ZEST is similar to SITA used on the HFA, but differs in the specific
algorithm details.

The 24-2 (55-point) and 30-2 (69-point) FDT full threshold tests are central 30 degree
visual field tests for use in gener

al visual field testing and glaucoma management. These
tests also provide a Glaucoma Hemifield Test that provides a plain language interpretation
of the visual field results based on an asymmetry analysis between test locations in the
upper vs. lower hemifield to detect glaucoma. The Glaucoma Hemifield Test (GHT)
messages include Within normal limits, Outside normal limits, Borderline, Borderline ­General reduction of sensitivity, General reduction of sensitivity, and Abnormally high
sensitivity.

The 10-2 (44-point) FDT full threshold test is a central 10 degree visual field test for use with
retinal disease (AMD, Diabetic Retinopathy) and end-stage glaucoma. The Macula
(16-point) FDT full threshold test is a central 5 degree visual field test subset of the 10-2 test.

On the left in the lower half of the full threshold test 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.

The lower total deviation plot, called a probability plot, translates the values from the
upper plot in

to shaded symbols which indicate the statistical significance of each decibel
deviation. These are explained in Table 4-2, “Probability Level Classifications”. The
darker the symbol, the less likely it is that the field is normal in that location (although the

elihood of abnormality also depends upon the actual prevalence of disease in the patient

lik
population). For instance, a totally black square indicates that the deviation from normal
found at that point location occurs in fewer than 0.5% of normal subjects. Notice that this
probability statement is made on a point-by-point basis, allowing you to read the results
like an isopter plot or graytone.

Humphrey Matrix User Manual 2660021138935 Rev. F 2015-11

Test Results and Reliability Measures

To the right of the total deviation plots are two additional plots, labeled Pattern Deviation.
These are similar to the total deviation plots, except that here the test results have been
adjusted for any changes in the height of the measured hill of vision caused, for example,
by cataracts or small pupils. Similarly, the software corrects for any patients who are
“supernormal”, adjusting the expected hill of vision upward by the appropriate amount
and thereby making the analysis more sensitive to localized scotomas.

Thus, the numeric Pattern Deviation plot shows the deviation in decibels from the age

ected normal values, adjusted for any shift in overall sensitivity. The pattern deviation

corr
probability plot indicates the statistical significance of the result at each point. Again, the
darker the symbol the more significant the deviation from the normal threshold value.

the population norms, a "p" value is given. For example, if p < 2%, this means that
fewer than 2% of the normal population shows an MD larger than that found in this
test. A significant MD may indicate that the patient has an overall depression, or that

ed to the normal reference field. If the deviation is significantly outside

Test Results and Reliability Measures

there is significant loss in one part of the field and not in others. MD is best inter­preted in relation to the Total and Pattern Deviation plots.

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.

Reliability Measures

When reviewing the results of the visual field test, give careful consideration to the
reliability indicators (catch trials). They are an important measure of patient reliability in
taking the test (and of the reliability of the results). They are indicated as a ratio of the
number responded to the number presented (as well as a percentage of the total). For
example, 1/10 (10%) indicates that the patient responded to 1 of the 10 catch trials
presented. If errors occur in greater than one third of the catch trials, the test results may
be unreliable.

Fixation Errors

The ratio of the number of times the patient responded to a target placed in the blind spot
versus the total number of times fixation was tested (i.e., total number of targets placed in
the blind spot). Fixation errors indicate the patient is not maintaining good fixation during
the test, is misaligned, or does not understand the test.

False Positive Errors

The ratio of the number of times the patient responded to a “pause” in the testing
sequence (i.e., no target presented) versus the total number of “pauses” in the testing
sequence. False positive errors indicate the patient is pressing the button even if the
patient does not see any patterns (trigger happy) or does not understand the test.

False Negative Errors

The ratio of the number of times the patient did not respond to a test pattern at the
maximum possible contrast level of the instrument versus the total number of times that
maximum possible contrast level patterns were tested. When possible, false negative catch
trials are only presented at locations where the patient has previously responded. False
negative catch trials are not used with screening tests. False negative errors indicate the
patient is likely not paying attention, does not understand the test, or has a severe loss at
the location of the false negative catch trial(s).

1. When you are ready to conduct the first test of the day, remove the Calibration Cap
from the Patient Eyepiece. Replace the calibration cap on the Patient Eyepiece when
the instrument is not in use to minimize the accumulation of dust and debris on the
Patient Eyepiece.

2. Check that the Patient Visor is in the correct position to test the corresponding eye. For
testing the RIGHT eye (factory default setting), position the Patient Visor so that it
extends past the housings on your RIGHT side when viewing from the Operator LCD
side of the instrument. This positions the Patient Eyepiece on the RIGHT side facing
the Patient Visor. If the Patient Visor is not correctly positioned, a popup message will
appear on the screen when the Start Test button is pressed.

Patient Correction

For accurate visual field test results, correct the patient to within the refractive error cited in
the table below. Use the patient’s habitual correction or a trial frame if needed. It is OK to
use bifocal or progressive lenses.

Patient Testing

Patient Seating and Position

1. Confirm the Patient Visor is in the correct position so that the Patient Eyepiece is
aligned with the eye to be tested.

2. Hand the Patient Response button to the patient and check that the patient is relaxed.

3. Adjust the position of the patient or the instrument to obtain proper, comfortable
patient alignment. Proper alignment requires the patient to see all four self-alignment
points at the same time while fixating on the black square target in the center. These
are illustrated on pages
fuzzy to the patient.

4. If you are using the Chinrest Module, you can use the Chinrest height-adjustment
knobs. Inform the patient to put his/her chin in the blue-marked chinrest for the right
eye, or the white-marked chinrest for the left eye. See

5. Align the patient’s head against the forehead rest by adjusting the table or seat height
for proper, comfortable head position relative to the instrument. Move the patient
toward the instrument if needed.

6. When Eye Monitoring is turned on, an image of the patient’s eye is displayed on the
Testing screen. Keep the patient’s pupil inside the circle on the video image
throughout the test. Keeping the pupil perfectly centered for proper alignment is not
necessary, but it should stay within the circle.

11-4, 11-5, and 11-6. It is OK if the fixation target appears

Chinrest Module on page 1- 8.

A very important factor affecting test reliability is the steadiness of the patient fixation.
Unless the tested eye accurately fixates on the target while responding to stimuli, there is a
possibility of unreliable results.

A comfortable patient position with good fixation is more important than obtaining or
keeping exactly centered alignment.

Explaining the Test Procedure to the Patient

Explain the test procedure to the patient as follows:

“The instrument is going to show you some patterns that flicker, or shimmer, or are striped.
Each time you see one of these patterns, press (and release) the button you have in your
hand. Please place and keep your forehead on the instrument forehead rest.”

“Can you see the black spot in the center of the screen? You must keep looking at the black
spot in the center at all times during the test.”

“While looking at the black spot in the center, can you see all four triangles at the edge of
the screen?”

“Are you comfortable?”

“A sample of the test is now running. Please press the button whenever you see a pattern
that flickers, or shimmers, or is striped. You may pause the test by holding down the
button. Releasing the button resumes the test. You may blink your eyes whenever you
want. A good time to blink is whenever you press the button.”

During testing, the stimulus may be more difficult to see than as shown in the pre-test demo.

Humphrey Matrix User Manual 2660021138935 Rev. F 2015-11

Patient Testing

“There is a brief flash just before the actual test begins.” [select Start Test button.] “The test
is beginning now. Please remember to keep looking at the black spot in the center of the
screen at all times during the test.”

It is a good idea to encourage the patient throughout the testing to help ensure proper
patient alignment, fixation, and attention. Remind the patient to occasionally blink.

Testing

Once the test preparations are complete and the patient is ready to begin:

1. Select the Start Test button located on the lower left of the TESTING Screen to begin the
test.

2. If the Patient Visor is not in the correct position for the test selected, the Patient
Response button is not connected properly, there is too much ambient light, or
calibration is needed, an error message will appear when the Start Test button is
selected.

Once the test starts there is a test progress bar indicating “Testing…” below the chart
display on the right side of the screen. The tested visual field location is indicated on the
chart display throughout the test. There are also two buttons on the lower left of the screen
to control the test:

5-13

Pause: Selecting this button pauses the test. When paused the progress bar will say,
“Paused…” and the Pause button changes to Resume Test. Pressing the Resume Test
button will resume the test.

Cancel: Selecting this button will bring up a prompt asking “Are you sure you want to
cancel the test?” Clicking on the No button will resume the test, while clicking on the
Yes button will delete the data collected during that test and bring up four options:

Re-Test Right (Left): Select this button to repeat the test on the same eye.

Test Left (Right) Eye: Select this button to test the opposite eye.

New Test: Select this button to bring up the original TESTING Screen for the same
patient for additional testing.

Done Testing: Selecting this button returns to the MAIN MENU.

At any time during the test the patient may press and hold the Response button to pause
the test. The test will resume automatically when the Response button is released.

Once the test for the first eye is complete the instrument will momentarily beep. Choose
one of the three options relative to testing the second eye:

Start Left (Right) Eye: Select this button to perform the same test type on the other
eye.

New Test: Select this button to bring up the original TESTING Screen for the same
patient for additional testing.

Done Testing: Selecting this button returns to the MAIN MENU.

5-14

Patient Testing

You may enter “Notes” or Patient “Information” at any time before, during or after the test
by selecting the appropriate tab. You may want to note how well the patient maintained
fixation during the test, for example.

At the completion of each eye test, the results are displayed on the Operator LCD. When
the testing for both eyes is completed, the results are automatically saved to the
instrument’s hard drive, backed up to a CD (if enabled), and sent to the default printer (if
enabled). Model 800 tests can also be automatically backed up and exported to a default
USB drive or network location. If DICOM Gateway is enabled, an ePDF can be
automatically exported to a DICOM System (see

2-5).

We recommend that you also back up your testing database every week from the MAIN
MENU (F1) or the FILE FUNCTIONS (F4) Screen.

Chapter Overview

The FILE FUNCTIONS (F4) Screen provides database management capabilities. A single testing
database is used on the Humphrey Matrix so all your visual field test results are available in
the working database.

Database Backup

You can back up the instrument’s testing database to a CD-R, USB drive , network location,
or floppy disk in Database Backup Format (.fdt2). Back up your database regularly. Select a
backup schedule that accommodates your business.

Note: A database backup creates a folder on the destination media named from the
instrument serial number (e.g., SN51111122222). The name of the backup file is created

om the instrument serial number and the date and time of the backup (e.g.,

fr
SN51111122222_FullBackup_05-11-2010_06.48.44_1.fdt2). Along with backup of test
data, a database backup also backs up the current user settings and system settings.

Note: Matrix System Software Version 8.0 creates a different database structure than
previous versions that is not fully compatible with previous software releases. When data is
imported fr
the Matrix 8.0 software will convert the data to the proper format. Matrix 8.0 data cannot
be imported into a Matrix running a lower version of software.

om 07.02.01 or lower Matrix software versions to version 8.0 software systems,

CAUTION: We do not recommend that you use optical disks (CDs) for long-term data

age or backup. Use should be limited to data transfer between systems. Take

stor
care to protect these media from damage. We recommend you use hard plastic

Conflict Resolution

In the File Functions menu under Database Import / Mer
Database, you have the option of setting the Conflict Resolution to Auto or Manual.

If Conflict Resolution is set to Manual and there are two of the same tests for a patient, or
two of the same patien

ts, one in the database and one on the restore media, the operator
will receive a prompt to decide which results are placed in the database. If Conflict
Resolution is set to Auto, and the Matrix software detects duplicate tests or patients, the
software will try to resolve the duplicates by automatically choosing one of them without
prompting the operator for confirmation. Occasionally, the operator will be asked to
examine the two tests or patients and make the decision because the software cannot
reliably choose the right course of action. Auto mode is considerably faster than Manual
mode, which always asks the operator to make the decision when a duplicate test or
patient is detected.

Note: When importing a database, if a patient conflict resolution dialog is presented and
the user asks for more test details, the Issuer of Patient ID (IPID) may be truncated. When
truncation is necessary

, it is done at the beginning of the string instead of the end because

the end of the string is more likely to be unique than the beginning of the string.

Risks of Internet Connectivity

CAUTION: When connected to the Internet, the Matrix may be vulnerable to serious
security risks, including viruses and worms that could disable your system or
adversely affect its performance.

WARNING: When networking the Matrix, use only network cables with an
unshielded RJ-45 connector. Use of a shielded network connector in the
Matrix could result in electrical shock to the patient and/or examiner.

Approved Third Party Hardware and Software

If you wish to use a third party device, seek technical support from the device
manufacturer. Repairs necessitated by the attempt to use a non-approved device are not
covered under warranty.

Note: Carl Zeiss Meditec does not provide technical support for the use of unapproved
third party hardware or software.

Using the Shared Network Folders

Using shared network folders is recommended in offices that have a local area network,
especially if you have multiple Matrix instruments. Once you have set up the instrument(s)
on the network, you can use the shared network folder for database backup and test
export.

Set Up Shared Network Folder

Note: Configuring the PC and the instrument for data transfer to a shared network folder
should be attempted only by a network administrator or system administrator.

Note: If you attempt a data transfer function when the network is down or the server is
down, the function will fail and the instrument will notify you that a connection could not
be established.

Networking Configuration

Configuration to a Pre-existing Office Network

This section explains how to configure the Matrix 800 to communicate via your pre-existing
office network (a local area network or LAN). To do this, the Matrix must be connected to
the office network by a standard network patch cable. It is the user’s responsibility to
install the necessary cables. Configuration topics, in order, are:

• Install the Network Cable, page 8-4

• Create a Shared Folder on Network File Server, page 8-4

• Configure Network Settings on the Matrix, page 8-13

• Add Network Shared Folders, page 8-14

• Selecting a Subfolder in a Network Share, page 8 -17

Install the Network Cable

Plug one end of a standard network patch cable into the Matrix Ethernet port (see on
page 1-7 ). Plug the other end of the cable into the 10/100 network switch. This switch
controls the bandwidth in and out of Matrix. Connect another standard network patch
cable between the swit

ch and the office network outlet.

Create a Shared Folder on Network File Server

To save your Matrix data, a shared folder needs to be created on the network file server, or on
a computer on the local network. For a Windows XP computer, see Create a shared folder

on a Windows XP computer below. For a Windows Vista or Windows 7 computer, see
Create a shared folder on a Windows Vista or Windows 7 computer on page
8-9.

Create a shared folder on a Windows XP computer
