Normative database allows
for more precise test results.
(p-value available even periphery up to 60°)
Kinetic perimetry is included as standard.
Static perimetry tests can be applied to areas of interest on fundus images taken from a retinal camera, OCT or SLO.
Threshold test within the central 10°, custom optional threshold test that allows selection of any desired test points, and custom optional screening test are available.

In addition to central 30° used to observe the progression of glaucoma, other tests are available such as central 10° which can identify visual field abnormalities in the macula.
GHT (Glaucoma Hemifield Test)
For this index, threshold central test points are divided into 10 sectors, and
corresponding sectors above and below the axis of the horizontal median are compared.
VFI (Visual Field Index)
A percentage index in which a normal visual field is 100% , and total loss of visual field
Anderson's Criteria Diagnostic Support Function
This criteria is for glaucomatous visual field defect.
If any of the following conditions are satisfied, the colors turn orange.
- PSD has p<5%
- GHT is outside normal limits
- Pattern deviation probability plot shows a cluster of 3 or more nonedge points
that have p<5%, and one of the points has p<1%
(The physician must judge whether the 3 points match the travel of NFL.)
Test result analysis indices can be graphically displayed as time series data to give a
clear grasp of changes over time in the tested eyes.
Predictive graphs are displayed from calculations of linear rates of changes in analysis indices.
This function predicts what values of MD and VFI will be reached at what age, if current rates of change in those values continue.
Main operation buttons are grouped at the top of the page, and buttons are laid out to follow the progression of tests, from patient information entry through test program selection to result display.
4-zone measurement that goes beyond
screening, and programs using probability
values (p-values), are among the features
that enable effective testing in less time.
Running tests with probability value (p-value)
intensities makes it possible to display
the difference between the measured value
and the normal value for each age range as
a p-value, so that the evaluation equivalent to
total deviation in thresholds can be performed in
a shorter time.
"Automatic measurement function", using
many median patterns, "Manual
measurement function", allowing free
drawing of isopters, and "auto + manual
measurement function", which allows any
drawing of median after automatic
measurement, are among the diverse
measurement method options available.
Perform perimetry tests on fundus images
Decibels, deviation maps, probability plots can be integrated with your patients fundus images.
Display with RGC displacement
Data from various threshold instruments can be imported. The imported
tests ensure that your patients VF history is maintained.
