OCULUS EASYFIELD

Easyfield®

The OCULUS Easyfield® is designed for use as a visual field screener and a threshold perimeter for immediate re-examination of any abnormal findings.

Description

Easy Operation

The Easyfield® Perimeter can be controlled via an external computer (Notebook or PC). The familiar user interface of the OCULUS programs is available on the computer and you can enjoy the full freedom of networking the examination data. The use of translucent Easyfield® occluders allows you to conduct examinations without the usual eye patch, thus saving you valuable time as you prepare for the examination.

 

FEATURES

As a screening unit, the Easyfield® Perimeter generally uses threshold related suprathreshold examination strategies. The advantage of this is that despite the short examination time, the examiner gains a meaningful overview of the examined area. Multiple test strategies are available for determination of the exact numeric values of the perception thresholds.  (We prefer not to promote CLIP anymore.) The OCULUS “Fast Threshold” achieves a similar performance with clever improvements to the classic 4-2 step method. The unique SPARK strategy provides a rapid and reproducible threshold measurement for glaucoma patients.

 

 

Results Printout

The measuring results of the Easyfield® Perimeter are summarized in a standard printout. For suprathreshold tests, only a single informational overview is printed, whereas for threshold examinations, all clinically relevant data are recorded and shown in various depictions.
