Introduction (continued)
Foresee PHP Technology
Foresee PHP technology is based on the well-studied visual phenomenon of hyperacuity.
Hyperacuity (also termed "Vernier acuity") is defined as the ability to perceive a minute difference
in the relative spatial localization of two or more visual stimuli (refer to Figure 0-1). The
hyperacuity threshold may be as low as 3 to 6 seconds of arc, which is approximately 10 times
better than the resolution ability (around 30-60 seconds of arc) in the fovea. The hyperacuity
stimuli are highly resistant to retinal image degradation, and thus suitable for assessing retinal
function in patients with opaque media as well.
Figure 0-1: Hyperacuity Diagram
When a dot-deviation signal is projected to a healthy retina, it stimulates a collinear set of retinal
receptive fields. Specialized neuronal circuits in the visual cortex process this information,
leading to the perception of a straight dot-deviation signal. When retinal pigment epithelium
(RPE) elevation occurs, both in the case of when drusen are present as in intermediate AMD,
and often to a more significant degree when CNV develops, a geometric shift in photoreceptor
location might occur. As a result, an object image that stimulates certain photoreceptor fields
when presented to a normal retina stimulates different ones when RPE is elevated. Therefore,
linear signals might be perceived as distorted or misaligned (refer to Figure 0-2).
Figure 0-2: Normal Retina vs. AMD with Photoreceptor Elevation
8
P/N 900F006-101 Rev. D
Introduction (continued)
Note: Figure 0-2 illustrates a simplified scheme of photoreceptor architecture. In the
normal retina, illustrated on the left, the two dots in the projected line activate
photoreceptor fields 2 and 6. This data is processed by the visual cortex and perceived
as a straight line.
However when the same line is projected on a retina with an AMD lesion, as illustrated in
the diagram on the right (in Figure 0-2), the geometrical shift of the photoreceptors
caused by retinal pigment epithelium [RPE] elevation, causes activation of
photoreceptors 2 and 7, instead of 2 and 6. Consequently, one of the dots is perceived
as if it shifted to another location in the visual field and the line appears distorted.
How the Foresee PHP Test Works
1.
The Foresee PHP test consists of a series of dot deviation signals (white dots on a black
background for maximum contrast) flashed at predefined intervals, across the central 14° of
the patient’s macular visual field.
2.
Projection of a dot deviation signal on a retinal lesion can cause the patient to perceive
distortion, scotoma, and/or blurring of part of the line.
3.
The patient is asked to report any abnormalities in the dot-deviation signal by touching the
screen at the location of the abnormality with the stylus. Existing visual field defects can be
identified should the dot-deviation signal be positioned on a lesion.
4.
During the course of the test, artificial distortions that imitate distortions similar to those seen
by patients with AMD related macular lesions, are flashed. These artificial distortions act as
both a quantifying measure and a reliability measure. The patient’s responses to these
distortions are evaluated to identify AMD lesions and to judge test reliability.
5.
The Foresee PHP system consists of a screen-based application that runs on the Foresee
PHP device. The patient’s responses are recorded and analyzed by a pre-designed
algorithm.
6.
Following the analysis, the resulting output indicates whether progression of AMD is
suspected or not.

Introduction (continued)
Foresee PHP Test Results
A test result on initial examination that was outside normal limits cannot serve as the baseline
examination. It is recommended to re-test the patient within 1-2 weeks. This may overcome
learning effects inherent to visual field testing.
Biomicroscopy is also recommended to rule out retinal pathologies. A test result that remains
outside normal limits on re-testing, excludes that eye from further monitoring with the Foresee
PHP.
A baseline examination (a result that is within normal limits and reliable) is the cornerstone for
interpreting test results. Subsequent examinations should always be compared to a previous
baseline examination.
Test results that indicate a change from the baseline, indicating a visual field defect that is
outside normal limits, probably indicates the presence of wet AMD. It is also important to take
into consideration the p-value on the report, which indicates the percentage of dry AMD patients
who may have a visual field defect that is outside normal limits.
Other pathologies or improper testing can also cause a visual field defect that is outside normal
limits.
Other pathologies that may cause visual defects include:
ΠAMD-related: Geographic Atrophy, Pigment Epithelial Detachment, Drusenoid PED, Scar.
ΠVascular: Vein Occlusion, Diabetic Retinopathy, Artery Occlusion.
ΠCentral Nervous
Determine if the Test Results are Reliable
If a test report is outside normal limits, the next step in making the diagnosis is to determine if the
test is reliable. To do so:
ΠReview the reliability indices and the overall test reliability.
ΠRetest an eye that demonstrated a visual field defect that is outside normal limits.
If both eyes showed results that were outside normal limits on the same examination day, this
indicates poor reliability. There is a low likelihood that wet AMD has developed in both eyes
simultaneously. The more experienced the technician and the patient, the better the results.
If the technician or the patient is relatively new to the Foresee PHP, take this into consideration
when reviewing the test results.
10
P/N 900F006-101 Rev. D
Introduction (continued)
Determine if there is Another Pathology Causing the Defect
If a test result is unreliable, determine if there is another pathology that may have caused the
visual field defect. To do so:
1. Check if the p-value is <10% or <5%. Although wet AMD may be present, some patients in
this group are expected to be negative for wet AMD.
2. Perform a comprehensive biomicroscopy exam to search for other pathologies that may
cause abnormal Foresee PHP results.
Remember, the Foresee PHP test is a subjective test for the diagnosis of wet AMD. A test result
that is outside normal limits may be an early indicator of progression to the more serious form of
AMD. You should apply your expertise to determine if further diagnostic measures and/or
referral are appropriate.

Calibration Monitoring
Foresee PHP has an integrated touch-screen calibration monitoring system. At regular intervals,
this system monitors the calibration status of the Foresee PHP touch screen and alerts you if a
calibration checkup is required. The date and results of the last calibration checkup (either
“failed” or “passed”) determine the calibration status, in light of the following system parameters:
 Checkup frequency (30 days): The maximal time allowed between calibration
checkups.
 Alert frequency (1 day): Alerts appear once a day, when the system needs to alert you.
 Prior notice interval (2 days): Alerts appear two days prior to reaching the maximal time
allowed between checkups.
There are four different statuses:
 The calibration is invalid. This means the last known calibration checkup failed.
 The calibration is overdue. This means the last checkup was performed more than 30
days ago.
 The calibration is due soon. This means the next checkup is due in two days (or, in
other words, the last checkup was performed 30 – 2 = 28 days ago).
 Calibration is okay.
An alert appears (refer to Figure 1-5) when any of the first three statuses exist. When an alert
appears, you have two options:
 Click Remind Later. This closes the alert dialog box and the system will send the alert
again in one day.
 Click Check Now. This opens the Calibration Checkup dialog box, which enables you to
perform a calibration checkup, and if required, calibrate the screen.
To perform a screen calibration checkup (refer to Figure 1-6), perform the following:
 From the Options/System Information screen, click Calibration Checkup.
 Select “Start a calibration checkup” from the Touch Screen Calibration screen.
Note: If the calibration status is Invalid or Overdue, the system prevents you from
performing a test until you check the calibration and make it valid again. If you click Start
when the calibration status is not valid, the system displays an alert dialog box.
Note: In addition, failing because of a touch-screen calibration problem, the calibration
checkup might fail due to inaccurate marking. If the checkup fails, attempt the calibration
check once more.
Note: If the “Start a calibration checkup” fails two times, the screen will prompt you to
“Calibrate screen”. Until this is performed, the system prevents you from performing a
test.

However, if the checkup fails more than twice, the system suspects that the touch-screen is,
indeed, not calibrated. Therefore, in case of repeated failure of the calibration test, an additional
option, Calibrate screen, is available (refer to Figure 1-7).
Clicking Calibrate screen invokes the touch-screen calibration application. Use this application

5. Ask the patient to rest their chin gently in the chin rest. Adjust the patient so they can easily
see both the top and bottom of the screen. Adjust chin rest, table height, and chair height
accordingly.
Note: The screen of the Foresee PHP device is lower than the patient’s face and
therefore the chin rest should be tilted slightly downward.
Note: Most patients can perform the Foresee PHP test with their own glasses. However,
you may use the PHP trial frame to provide near distance correction for patients with
bifocals.

Introduce the patient to the various tasks to be performed during the actual test.
Train the patient to identify distortions and to mark them on the touch screen, using the
stylus.

P/N 900F006-101 Rev. D
2. Running the Foresee PHP Test (continued)
The tutorial consists of a stationary signal section and a flashing signal section.
Definitions
Fixaton Target:
Distortions:
Stationary Signal:
Home Base:
A white dot in the center of the screen that the patient should fixate on
during testing.
Curved locations on a straight Stationary Signal that the patient
identifies during the test.
A dotted signal line with distortions that appears on the screen during
testing to enable the patient to identify the distortions.
The triangular pad the patient places their hand on after marking a
distortion.
The tutorial was designed to teach the patient to mark distortions accurately.
Whenever the patient marks the location of a distortion on the screen, a white dot
appears on the screen. The distance between this white dot and the actual
distortion is calculated. Only when the patient marks the distortion accurately (and
a beep is heard) and the distance calculated is small, does the stationary signal
disappear. The signal disappearing indicates to the examiner that the patient
performed the task correctly and, after ensuring that the patient’s hand is located
on the home base, the examiner can continue the tutorial by pressing the space
bar.
If, however, the stationary signal did not disappear, pressing the space bar will not
trigger the next signal. In such a case, the examiner should instruct the patient to
mark the distortion again, this time being more careful to mark it accurately and
return their hand to the home base.
Note: If the patient cannot identify or mark the distortions presented in the stationary
signals, the patient should be disqualified from performing the test.
Note: The first few times that a patient attempts to mark the screen, the patient might
not be able to estimate their distance from the screen or they might be afraid to touch
the screen with enough pressure to actually mark on the screen. If the patient touches
the screen and the white dot fails to appear or the beep is not heard, instruct the patient
to press harder when touching the screen. Explain to the patient that this is a touch
screen and there is no problem touching it with the stylus.
Note: The patient’s hand must return to the home base following the marking of each
signal. This indicates that the patient completed marking the distortions and assures
that the patient’s hand is not obstructing the screen.
Note: If there is more than one distortion, the patient must mark all distortions
accurately in order to make the signal disappear and to enable the examiner to continue
the tutorial.

Explain to the patient what they will see during the tutorial: the Fixation Target, the Stationary
Signal (dotted signal line), and Distortions. Ask them to point where the distortions of the
Stationary line are located on the screen using the stylus.
1. Instruct the patient to use the stylus to touch the screen and to mark the location where the
distortions appear.
2. Instruct the patient to return their hand to the home base after marking the screen.
3. Encourage the patient to do their best and that if they do not see distortions the test may
include stationary signals without distortions.
4. Explain to the patient that they can use as much time as necessary to mark the distortions.
5. If the distortions are not marked accurately and the signal did not disappear, instruct the
patient to mark the distortions again as accurately as possible.
To continue to the next signal:
Œ Wait until the patient’s hand is returned to the home base and press the spacebar.

Tutorial - Flashing Signal Section
After the stationary signal section of the tutorial is complete, the following banner appears.
Figure 2-9: Flashing Signal Banner Screen
The banner indicates that the flashing signal section of the tutorial is beginning and reminds you
to instruct the patient to notice the distorted areas on the flashing lines, and mark them after they
disappear from the screen.
The flashing signal section of the tutorial tests the patient’s perception. This means that the
patient may see different distortions than you do. Because of this, the patient should not be
corrected during this section of the tutorial. This section of the tutorial is the same as the actual
test and enables the patient to practice marking distortions before actually taking the test.
Press the space bar. The banner drops and the first signal flashes.
For the flashing signal section of the tutorial:
1.
Explain to the patient that the flashing signals appear on the screen for a very short time.
2.
Instruct the patient to mark the area on the screen where the distortion flashed after it no
longer appears on the screen.
3.
Remind the patient to return their hand to the home base after marking the distortions.
4.
Inform the patient that:
32
•
If the patient sees more than one distortion on the flashing line, they should mark
each distortion.
•
If the patient did not see any distortion on the flashing line, they should not mark
anything and the patient’s hand can remain on the home base.

signal.
To continue to the next signal:
Wait until the patient’s hand is returned to the home base and press the space bar. Pressing
the space bar while the patient’s hand is off the home base will not trigger the next signal.

Performing the PHP Test – First eye
After the patient has successfully completed the tutorial, the patient immediately begins the test.
The Foresee PHP test consists of flashing signals with distortions. As in the tutorial, the patient
should mark the perceived distortions after they disappear from the screen. The test is operated
by the patient and does NOT require you to press the space bar to trigger signals. In the test,
the system automatically flashes a new signal after the patient’s hand has been returned to the
home base. If the patient’s hand remains on the home base for a certain length of time, the
system automatically triggers the next signal. For example, this can occur if the patient does not
perceive any distortions for a certain interval.
Note: It is recommended that you watch the patient for the first few signals to make sure
the patient is marking distortions and returning their hand to the home base.
Make sure to encourage the patient, but do not correct the patient at any time during the test.
Due to the patient’s clinical condition, the patient may see distortions that do not exist on the
signal and might fail to see distortions that exist on the signal.

Results
Within Normal Limits means that similar visual field findings are found in the normal population of
intermediate AMD patients (dry AMD) in the normative database. Note, that in a small percentage
of cases, CNV patients may produce test results of a visual field that is within normal.
Outside Normal Limits means that similar visual field findings are found in the population of CNV
patients (wet AMD) in the normative database.
If the deviation is outside normal limits, a “p” value is given. For example; p < 10% means that the
visual field defect in this test is found among 10% of the intermediate AMD population. This
information may help you decide what measures you will take in further evaluating this case.
Categories for p values are: p < 10%, p < 5%, p < 1%.
Reliable indicates if the overall test performance is reliable. It can be either YES or NO. The test is
reliable only if both reliability indices (refer to below) are reliable. When at least one of the indices is
unreliable, the test is to be considered as unreliable.
Œ
Baseline Test: Indicates whether a baseline examination (a test that is within normal limits and
reliable) is available. Without a baseline examination, monitoring of an eye and indication of
change can not be made.
Œ
Reliability Indices: These indices determine the reliability of the examination. There are two
indices:
Œ
False Negative Errors: This index indicates the frequency with which the patient failed to
respond to stimuli expected to be visible.
Œ
False Positive Errors: This index indicates the frequency with which the patient responded to
stimuli that could not have been seen. Each of the above indices can be either Reliable or
Unreliable, as indicated using a bar chart for each index. This bar chart also provides a
measure for the level of reliability. If the black triangle indicator points to the blue part of the
bar, the index is reliable. If it points to the black part, it is unreliable.

Exporting Test Results
Foresee PHP enables you to export PHP test results to a local disk drive, a network drive, or to a
removable storage device. For example, you can use the “Export” flash drive connected to your
Foresee PHP device to export a selection of test results to a PC. After exporting, you can unplug
it from the device and plug it into the USB port of a PC where the results can be viewed. Since
the exported files are stored in standard formats, there is no need for a dedicated viewer in which
to view these results.
To export Foresee PHP test results:
1. Click the arrow next to the Export button. A menu pops up:

If the selected format for export is .bmp or .jpg, two separate .bmp/.jpg pages will be
created having “part 1” and “part 2” in the file name correspondingly.
5. If you want to exclude the patient details in the exported file(s), clear the Include patient
details check box (by default, tests are exported with patient details). Using this option will
result in non-significant file names to the exported files.
6. If you do not want to overwrite files of tests that might already be on the export disk, uncheck
the Overwrite existing files check box. (By default, if a test is already on the removable
export disk, it will be overwritten.)

A message that indicates whether the backup disk is: Plugged or Unplugged.
Copying to Backup/Local Disks
The Foresee PHP device uses a removable storage disk for backup storage. Each regular test
requires approximately 50KB. Therefore, a removable storage disk of 128MB will hold
approximately 2500 Foresee PHP tests.
After a removable storage disk is plugged in and initialized as a backup disk, backup occurs
automatically by default.
Note: The backup removable storage disk supplied with the device is already initialized to
be a backup disk.
When the backup disk is full, you can replace it with an empty removable storage disk that was
initialized as a backup disk (refer to Initializing a New Backup Disk, page 74).
It is highly recommended that you store a full set of backup disks in a secure location.
In case of a full backup disk or a disconnected backup disk, the appropriate message will appear
in the Save dialog box.
It is possible that tests saved to the local disk are not backed up to the removable storage disk.
The field Tests stored on the Local disk, but not on the Backup disk indicates the number of tests
not backed up to the removable storage backup disk. It is strongly recommended that you back
up such tests, using the following procedure.
To copy tests to a Backup disk:

• Overwrite old tests as needed (not recommended).
• Do not overwrite tests (clear disk manually or initialize a new Backup Disk).
Automatic Backup Option
When its checkbox is selected, Automatically backup a test when saving, it means that when
you save a test result, it is copied automatically to the backup removable storage disk. It is

to Initializing a New Backup Disk, page 74).
Clear the check box to disable automatic backup. In this case, you must back up test results
manually using the Copy to Backup Disk button (refer to Copying to Backup/Local Disks, page

Initializing a New Backup Disk
Before using a new backup storage disk, you must initialize it. The Foresee PHP application
provides you with a database tool that enables you to initialize a new backup disk.

message.
Figure 5-19: Backup Disk Initialized Successfully Message
Note: If you attempt to initialize more than one removable backup disk, the Foresee PHP
application will recognize the last disk initialized only. You cannot initialize more than one
and use them interchangeably. In case you remove an initialized disk from the device
and then plug it back in and attempt to initialize it, you receive a message indicating that
this backup disk is already initialized.
Cleaning Test Results from the Local Disk
This option will permanently delete all test results from the device’s local disk. This operation is
irreversible, and therefore should be used only in very rare cases (e.g., when instructed to do so
by customer support). Do not use this option unless you are perfectly sure it is necessary. If you
are forced to clean the database, it is highly recommended to manually backup any test results
you want to retain before performing this operation.
After you click Clean Local Disk, Foresee PHP permanently deletes the test results from the
local disk.
To delete test results from the local disk: be specific according to “clean” screens:
1.
From the Database Tools screen, click Clean Database.
A confirmation dialog box opens, indicating that the deletion is permanent.

The recovery feature provides a mechanism for preventing loss of test data due to unexpected
errors (e.g. after power failure).
In such cases, during next system startup you will be prompted with a corresponding message
allowing you to load the recovered test(s):

9. Terms, Conditions, and Warranty
This product is warranted by Reichert, Inc. against defective material and workmanship under normal use for a period
of one year from the date of invoice to the original purchaser. (An authorized dealer shall not be considered an
original purchaser.) Under this warranty, Reichert’s sole obligation is to repair or replace the defective part or product
at Reichert’s discretion.
This warranty applies to new products and does not apply to a product that has been tampered with, altered in any
way, misused, damaged by accident or negligence, or which has had the serial number removed, altered or effaced.
Nor shall this warranty be extended to a product installed or operated in a manner not in accordance with the
applicable Reichert instruction manual, nor to a product which has been sold, serviced, installed or repaired other than
by a Reichert factory, Technical Service Center, or authorized Reichert Dealer.
Lamps, bulbs, charts, cards and other expendable items are not covered by this warranty.
All claims under this warranty must be in writing and directed to the Reichert factory, Technical Service Center, or
authorized instrument dealer making the original sale and must be accompanied by a copy of the purchaser’s invoice.
This warranty is in lieu of all other warranties implied or expressed. All implied warranties of merchantability or fitness
for a particular use are hereby disclaimed. No representative or other person is authorized to make any other
obligations for Reichert. Reichert shall not be liable for any special, incidental, or consequent damages for any
negligence, breach of warranty, strict liability or any other damages resulting from or relating to design, manufacture,
sale, use or handling of the product.
PATENT WARRANTY
If notified promptly in writing of any action brought against the purchaser based on a claim that the instrument infringes
a U.S. Patent, Reichert will defend such action at its expense and will pay costs and damages awarded in any such
action, provided that Reichert shall have sole control of the defense of any such action with information and assistance
(at Reichert’s expense) for such defense, and of all negotiation for the settlement and compromise thereof.
PRODUCT CHANGES
Reichert reserves the right to make changes in design or to make additions to or improvements in its products without
obligation to add such to products previously manufactured.
CLAIMS FOR SHORTAGES
We use extreme care in selection, checking, rechecking and packing to eliminate the possibility of error. If any
shipping errors are discovered:
1.
Carefully go through the packing materials to be sure nothing was
inadvertently overlooked when the unit was unpacked.
2.
Call the dealer you purchased the product from and report the
shortage. The materials are packed at the factory and none
should be missing if the box has never been opened.
3.
Claims must be filed within 30 days of purchase.
CLAIMS FOR DAMAGES IN TRANSIT
Our shipping responsibility ceases with the safe delivery in good condition to the transportation company. Claims for
loss or damage in transit should be made promptly and directly to the transportation company. If, upon delivery, the
outside of the packing case shows evidence of rough handling or damage, the transportation company’s agent should
be requested to make a “Received in Bad Order” notation on the delivery receipt. If within 48 hours of delivery,
concealed damage is noted upon unpacking the shipment and no exterior evidence of rough handling is apparent, the
transportation company should be requested to make out a “Bad Order” report. This procedure is necessary in order
for the dealer to maintain the right of recovery from the carrier.
