Description
The Kowa AP-7000 is an automatic perimeter developed for comprehensive visual-field testing in ophthalmology and optometry practices. It combines static and kinetic perimetry, multiple threshold and screening programs, advanced analysis tools and a normative database covering central and peripheral visual-field results.
Full-threshold programs provide macular, central and peripheral examination up to 80°. Quick and Super Quick strategies help shorten examination time, while specialized screening programs support rapid visual-field evaluation. Kinetic perimetry is included as a standard function and can be performed automatically or manually.
Fundus-oriented perimetry allows static visual-field test locations to be associated with retinal images obtained from compatible fundus cameras, OCT or SLO systems. Clinicians can select specific areas of interest on the retinal image and correlate functional results with anatomical findings.
The AP-7000 supports white, red, blue and green stimuli in Goldmann sizes I through V. It also provides Blue-on-Yellow testing and multiple analysis indices, including Mean Deviation, Pattern Standard Deviation, Total Deviation, Pattern Deviation, Glaucoma Hemifield Test and Visual Field Index.
Fixation can be monitored using the Heijl-Krakau method, an eye-fixation monitor and gaze monitoring. Examination results can be compared chronologically to help identify visual-field changes over time.
Its compact ergonomic enclosure, color touch-screen interface, motorized chinrest and spoken instructions help simplify operation and improve the examination experience. USB and Ethernet connections support data management, external printing and integration into compatible clinical networks.
