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. Without question, one of the
most essential tools in the modern ophthalmic office is the automated perimeter, used to evaluate
the visual field.

visual fields play a major role in identifying visual field defects and evaluating the efficacy of the
therapy used to control the disease process.

What Visual Field Tests Measure

When evaluating visual performance, clinicians ar
resolution and contrast sensitivity. Resolution is the ability to identify discrete forms (letters,
numbers, symbols), and is commonly measured with the visual acuity test. Resolution rapidly
diminishes with increasing distance from the fovea and is, therefore, a poor indicator of overall
visual performance.

A better means of evaluating visual function—especially
is contrast sensitivity testing. Contrast sensitivity is the ability to detect a stimulus (spot of light or
other target) against a darker or brighter background. Humphrey perimetry may be thought of as
contrast sensitivity testing applied throughout the peripheral visual field.

In perimetry, the term “threshold” is used to describe
threshold represents the point at which a stimulus is seen 50% of the time and missed 50% of the
time. The assumption is that all stimuli brighter than the threshold value will be seen and all stimuli
dimmer will be missed. Reviewing the threshold value at each point tested in the visual field is an
important part of the diagnostic process.

a fixed point.

Figure 1.2 The Boundaries of the Normal Visual Field

A more comprehensive understanding of the normal field takes into account that visual sensitivity is
not constant (or equal) throughout the range. As previously stated, vision is most acute at the fovea
and decreases toward the periphery of the retina. It is easy to see why the visual field is often
expressed as a “hill of vision in a sea of darkness”.

Figure 1.3 The Normal Hill of Vision

Several factors affect the normal hill of vision, causing variations in its overall height and shape.
Among them are a patient’s age, ambient light, stimulus size, and stimulus duration. In general,
deviations from the normal hill of vision are viewed as visual field defects and caused by some
pathological change.

A visual field defect, or scotoma, is categorized as either re
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

Humphrey Field Analyzer II-i series User Manual 2660021145640 A

Introduction & Instrument Setup

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.

Methods of Testing the Visual Field

Over the years, visual field testing devices have varied in size, complexity
The fundamental premise has remained the same, however; patients must respond when they see a
stimulus.

Static threshold testing evaluates retinal function. The te
being used. In static testing, predefined test locations in the visual field are probed. Through a series
of stimulus presentations of varying brightness intensities, the threshold value is determined for
each test point. When evaluating static test results, clinicians are looking at the topography or
contour of the hill of vision, and whether depressions are evident.

In a second type of retinal evaluation, called kinetic testing, a
is moved into the visual field from a non-seeing area, until it is detected by the patient. Typically, the
stimulus is brought toward the center from several directions and the operator marks the location at
which the patient first detects the stimulus (threshold point).

Kinetic test results can only be reliably related to specific parts of the visual field if points are joined
to form an isopter
used during one kinetic test, and for each different target, a different isopter is mapped. When
reviewing several isopters, the clinician is visualizing different tiers in the hill of vision.

Patient Fixation and Test Reliability

In order for any visual field test to be useful clinically
factor affecting reliability is the steadiness of patient fixation. Unless the eye being tested fixates

Introduction & Instrument Setup

CAUTION: Carl Zeiss Meditec has tested and verified the operation of the parallel port
supported printers. It is the HFA II-i owner’s responsibility to ensure that any
unsupported printer that is used with the HFA II-i in their medical environment
satisfies the appropriate medical directives and International Safety Standards.

Note: Carl Zeiss Meditec periodically creates and releases upgrades of the system software used on
its instruments, including the HFA II­upgrades with all makes and models of currently available commercial printers. As a result, the
operability of unsupported printers may be affected adversely by such future software upgrades

data on USB devices can become corrupted when inserting into computers for
backup or transfer. The use of anti-virus software on computers is recommended and
is the responsibility of the user.

CAUTION: To protect your HFA data from unauthorized access, use dedicated USB
devices for storage of HFA data. Do not use these USB devices for any other data or
application. HFA data is not encrypted.

CAUTION: Health care providers have responsibility for the protection of patient
health information (PHI), both hardcopy and electronic. To protect patient
confidentiality of your electronic HFA data, the use of encryption is recommended
and is the responsibility of the user.

Note: The HFA is only compatible with USB storage devices formatted in FAT (FAT16) or FAT32. NTFS
or exFAT (FAT64) cannot be used and will report an “Unrecognized format” error. Also, the HFA can
only see and access the first partition of the USB storage device.

Note: Some USB hard drives may require connection to two USB ports or their own external power
supply to work correctly.

Note: An optional USB floppy disk drive should only be used for backwards compatibility. It is highly
recommended to use USB storage devices instead of floppy disks. Floppy disks may not be available
in the near future.

Test Library Notes

There are a number of different uses for the tests included with your HFA II­settings or conditions that are important to understand if you are to perform the test correctly.

• The Bottom LED fixation target is automatically used by the HFA II­the Superior 36 point or Superior 64 point Screening Test. Remember to direct the patient’s
fixation to this lower target. If you manually set the Central target to be used with either of the
Superior Field tests, some of the most superior points will be omitted from the test pattern.
These two tests should be run in the Single Intensity mode with the stimulus set to 10 dB. If you
use these tests often, refer to “Altering the Main Menu Screen,” on page 2-26, for information
on how to place the test on the Main Menu with the 10 dB stimulus permanently set.

• The Full Field tests are run in two parts: first the cen
portion. If a trial lens is necessary for the central portion, the HFA II­lens holder is in the up position and pauses the test at the completion of the central portion.
An alert advises you to remove the trial lens and put the trial lens holder in the down position.
You may then start the peripheral portion of the exam. If the patient does not require a trial
lens correction at the start of the exam (trial lens holder in the “down” position), the Full Field
test will run to completion, testing both the central and peripheral visual field without pausing.

• The Full Field 135 Screening Test will not display all tested

Much like the Snellen scale for central acuity, the Esterman scale is especially
visual capability or disability in industry, law, and government (workers’ compensation, motor
vehicle, aviation, and military). The Esterman test is listed as an option for many disability
screenings. Carl Zeiss Meditec is grateful to the American Academy of Ophthalmology for providing
us with the rights to offer the Esterman test for your use.

The Esterman test scores are based on a relative value scale, which is d
100 for monocular tests and 120 for binocular tests. Each unit is equated to one test point and is
given a value of 1% in the monocular field and 0.83% in the binocular field. The inequality in the
size and distribution of the units, with greater unit density in more important areas, makes the scale

Entering Patient Data

Once you have selected the test and test eye, you will be ready to input patient data. You can input
a variety of information about your patient each time he or she takes a visual field test. The patient
data section is divided into two main screens: Patient Data 1 displays demographic and trial lens
information; Patient Data 2 displays diagnostic information. The required entries on the Patient Data
1 screen are Patient ID, Patient Name and Date of Birth. You need not enter all information
requested; however, always enter a patient ID, a name and date of birth since they are required for
trial lens calculations, data analysis, and saving the test to disk. If a Patient ID is not entered, one is
automatically created. Also Gender will default to UNKNOWN.

Note: The HFA II-i 5.x database is different from previous software versions in what determines
patient uniqueness. To be compatible with EMR/PMS/DICOM systems, a Patient ID is now required.
In the 5.x database, a patient is determined to be unique by only two fields—Patient ID and Issuer
of ID. A Patient ID is required, but the Issuer of ID is optional. Issuer of ID (Issuer of Patient ID) is a
DICOM data field to specify the assigning authority of the Patient ID. See “Patient Uniqueness—

Patient ID and Issuer of ID,” on page 14-39, and “Specifying Your Practice’s Issuer of ID,” on
page 14-40.

How to Calculate the Spherical Equivalent
The spherical equivalent is equal to half of the power
the spherical equivalent of +1.00 DC is +0.50 D. The spherical equivalent of -0.50 DC is -0.25 D.
You add the spherical equivalent of the cylinder power to the original spherical power to get the
overall spherical equivalent. Refer to the “Examples of Trial Lens Correction,” on page 3-21 for
additional examples.

3Place the sphere lens in the slot closest to the patient (in front of

the cylinder lens).

Note: Use only the narrow rimmed type of trial lenses. The wide-rimmed variety will interfere with
the patient’s peripheral vision and adversely affect test results. It is helpful to move the lens handle
towards the patient’s temporal side so it does not interfere with the patient’s eye brow or nose.

Preparing the Patient

How well your patient understands the test procedure and how comfortable he or she is while
taking the test directly influences the reliability of the test results.

Patient Instructions for Static Testing

Explain the test procedure clearly and completely. Answer all
the following patient instructions as a guide, but remember to tailor your instructions to the
patient’s individual needs.

“This test will measure your cent
ahead at the steady yellow light (Point to yellow fixation light). Other lights will flash one at a time
off to the side. Some will be bright, some dim. Press the button whenever you see one of these
lights (Give patient the response button). You are not expected to see all of them.” For threshold
tests: “The test is designed so that you may see fewer than half of them.”

“If you want to rest, hold down on the button (demonstrate to patien

good time to blink is whenever you push the response button. When your test is over, you will hear
two beeps. You may sit back at that time.”

Note: Instructions for Kinetic Testing differ slightly. See Chapter 13 for details.

Occluding the Non-Test Eye

Position the eye patch over the non-test eye so that it completely blocks vision, as shown in the
