Smart Supra: the best of supra-threshold and threshold perimetry
The Henson 9000 includes a unique supra-threshold algorithm designed to provide
a solution to the three main problems affecting visual field tests today.

3 main problems
with current visual field tests
High variability at moderate to severely damaged test locations (<20 dB).2,3
Poor sensitivity to small central defects when testing with the 24-2 test pattern.
Long test times only get longer with the inclusion of more test locations.

3 solutions
from Smart Supra
Smart Supra replaces the need to test at locations below 20 dB where variability is so high that meaningful measuresof threshold are not attainable [Fig.1]. It does so by setting the threshold increment according to the normal variability
found at each location** allowing it to test at levels which have a 95, 98 and 99% probability of being seen [Fig. 2].

Smart Supra includes 32 additional points in the central 10 degrees in response to recent research showing that small centralEquality

defects can be missed by 24-2 field tests.1
Range ofnormalthresholds

20Smart Supra is fast even with three levels of testing. Its easy, in-test extension from 30 points (suﬃcient to screen low-riskpatients in under a minute) to 64, then 86 points (3.5 minutes) as required, allows Smart Supra to test more points in less time.

accounting for the known issue of increased variability at eccentric locations.

Management with ZATA threshold testing
Further to the advantages of Henson Smart Supra, the Henson 9000 also offers a threshold test for the detection andmonitoring of visual field loss .

The Zippy Adaptive Threshold Algorithm (ZATA) developed by Professor David Henson uses the more eﬃcient Bayesian
method to derive threshold values. Bayesian methods were first introduced into perimeters in the SITA algorithm of theHumphrey Field Analyzer. ZATA further developed this method with reference to research demonstrating enhanced variability
at test locations with depressed sensitivity.3,4 The ZATA test can typically be completed in as little as 3 minutes per eye.*

5 reasons to choose ZATA
Speeds up threshold testing through better use of prior test data
In instances where patients have been tested previously, ZATA will build on this prior data for subsequent tests, ratherthan starting a new test from age normative data as is common in other perimeters. This helps negate false positive
responses early in a test by patients with established loss and serves to reduce patient anxiety, too, by reducing thenumber of unseen presentations. It can also speed up test times – benefiting patients and enhancing practice workﬂow.

Does not just use single terminating criteria
ZATA varies the terminating criteria to give more accurate thresholds at damaged and neighboring locations.
This reduces test times, both for patients with advanced visual field loss and for those with no loss at all.

Uses looser terminating criteria in severely damaged locations (<10 dB)
ZATA does not attempt an accurate measurement of thresholds below 10 dB where variability
is high and attempts at accurate measures do not yield any useful additional data.

Allows both 24-2 and 30-2 stimulus patterns in a single test
Via a simple ‘extend’ facility operators can extend the 24-2 test pattern to a 30-2 test pattern during or at
the end of each test so avoiding the need to retest the 24-2 locations if later opting for a 30-2 test.

Uses standard printout for universal compatibility
The standard print format is used to aid interpretation and comparison with data from otherperimeters. The Henson 9000 software also allows users to switch between multiple views– threshold, grayscale, or defect values – on screen at the end of each test.

*Test times are approximations only and will differ according to patient response time and level of loss.

Putting it into practiceAll the visual field tests and analytical tools you needYou have all the tools you need to detect and monitor functional loss with our range of supra-threshold and thresholdtests, as well as monitoring the whole visual field with the Esterman binocular driving tests (Groups 1 & 2).

We understand that our equipment must fit seamlessly into your practice and processes. The Henson 9000 is a low
maintenance, compact perimeter for ﬂexible positioning with networking facilities available as standard. Its suite of tests andassociated analytical techniques give you all the information you need to support the best patient outcomes.

Small footprint allows for ﬂexibility of positioning. The Henson 9000 has a compact footprint and sits easily on a standard
instrument stand. The software runs on a separate device (touch screen, desktop or laptop), giving you more placement
ﬂexibility than is available from perimeters with fixed operator display screens.

Smart Supra results are designed to be compatible with threshold results, while our ZATA
results include recognized global indices (mean deviation, pattern standard deviation andhemifield) plus threshold and grayscale, total deviation and pattern deviation values.

Progression analysis tools display global indices (mean deviation and pattern standard deviation)
against the age of the patient and the mean deviation rate of change displayed with confidence levels.

Full networking support. The Henson 9000 application can make full use of the networking facilities within Windows®
as standard. There is no need to purchase additional software to enable this. The Henson software can utilize the network
for printing or to allow storage of the database, backup or output files on a network drive, enabling the sharing of test data
between units. Networking also allows remote practice management systems to pass patient details to the Henson tests. TheProgression data can also be presented on Glaucoma Staging System II (GSS2). Using both the mean
deviation and pattern standard deviation is better than using either index in isolation.

ZATA threshold test includes a foveal threshold measurement facility as standard.

results of the tests can be stored in multiple locations as JPEG, PDF or DICOM images.
