30 Years of Perimeter Experience, and It Just Got Better! AP-7000 Kowa's extensive normative database considers both the central field and the periphery thus ensuring consistent, accurate assessments when using a Kowa AP-7000 perimeter. Full threshold modes offer macular, central, and peripheral coverage up to 80°, while screening modes provide swift evaluation of the visual field. To shorten test times, quick modes are available for both threshold and screening modes. Static perimetry can be linked with fundus images from cameras, OCT, and SLO to define specific test locations on the retina. With its ergonomic, compact design, the AP-7000 offers additional comfort to patients, easy operation for the clinician, and fits perfectly within the practice. Features and Benefits Database of Normal Eyes Database of Normal Eyes Normative database allows for more precise test results. Kinetic Perimetry Kinetic Perimetry Kinetic perimetry is included as standard. 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 tests are available.

Clear Display of Analysis Results Clear Display of Analysis Results 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 Screening 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. Screening 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. Isopter 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.
