Database of Normal Eyes
 
 
Database of normal eyes measured periphery 60° enables more precise judgement of periphery test results.
Kinetic Perimetry
 
 
This function is equipped as standard specification.
Fundus Oriented Perimetry
 
Static perimetry test can be applied to abnormal sites on a fundus images, such as a fundus photograph, OCT or SLO.

Threshold test within the central 10°, custom optional threshold that allows selection of any desired test point, and custom optional screening tests are available.
Threshold Macula 2 test, Custom opticonal threshold test and Custom optional screening test are available.
Threshold Macula 2 test examins within the central 10°, Custom optional tests allow selection of any desired test points.

Threshold

In addition to test within the central 30° that can observe the progression of glaucoma, test is possible in a wide variety of range, including central 10°, which can identify visual field abnormalities in the macula.

Clear Display of Analytical Results
 
Analytical Indices
 
GHT (Glaucoma Hemifield Test)
For this index, threshold center test points are divided into ten 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 field is 0%
Anderson's Criteria Diagnostic Support Function
If one or more of three consecutive points satisfy one or more of the conditions "PSD has p<5%", "GHT outside normal limits", or "patern deviation probability plot shows a cluster of three or more nonedge points that have p<5%, and one of the points has p<1%" this indicator judges the condition to be a glaucoma visual field abnormality. (The physician must judge whether the three points match the NFL movement.)
Chronological Change Display
 
Test result analytical indices can be graphically displayed as time series data to give a clear grasp of changes over time in the tested eyes.
 
Predictive Display
 
Predictive graphs are displayed from calculations of linear rates of changes in analytical indices. This function predicts what values of MD and VFI (Visual Field Index) 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.
 
Screening

4-zones measurement that goes beyond screening, and programs using probability values (p-values) in intensity steps, are among the features that enable effective test in less time.

Running tests with intensity of probability value (p-value) makes it possible to display the difference between the measured value and the normal value for each age as a p-value, so that evaluation equivalent to total deviation in thresholds can be performed in a shorter time.

Isopter

"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.
