The AP-7000 is Kowa’s next generation automated perimeter that offers an extensive variety of test strategies and screening programmes. It provides reliable and consistent assessment results due to its normalised database. Full threshold modes offer macular, central and peripheral coverage up to 80° whilst screening modes provide swift evaluation of the visual fi eld for relative or absolute scotomas. To shorten test times quick modes are available for both threshold and screening modes. Furthermore, by automatically correlating the fundus image (from a fundus camera, OCT or SLO) with the static visual fi eld, early detection of glaucoma is possible. With its ergonomic, compact design, the AP-7000 offers additional comfort to patients, easy operation for the clinician and fi ts perfectly within the practice.

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.

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.)

VFI (Visual Field Index)
A percentage index in which a normal visual field is 100% and total loss of field is 0%
