    Database of Normal Eyes

    Normative database measured periphery 60°
    allows for more precise test results.

  • Kinetic Perimetry

    3 methods are available :
    ・Auto + Manual

Fundus Oriented Perimetry

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.

Analysis Indices

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
is 0%

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.)

Chronological Change Display

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.

Chronological Change Display

Predictive Display

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.

Convenient Tabbed User Interface

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.

Convenient Tabbed User Interface


  • 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.
