OCULUS Easyfield® Perimeter

The right choice for all your needs

The OCULUS Easyfield® is a full-fledged compact perimeter capable of performing standard automated perimetry of the central visual field up to 30° eccentricity. It has been designed for the combined use as visual field screener and perimeter, offering features usually available only in large units. The spherical bowl with 30 cm (11.81”) radius is enclosed into an ergonomically movable cone equipped with a distance adapted lens. The OCULUS Easyfield® conforms to the Goldmann standard and fulfills the ISO-12866 norm for perimeters.

Measurements of the OCULUS Easyfield® are carried out using an LED grid with 135 fixed test locations, including the common 30-2, 24-2 and 10-2 patterns. The novel SPARK test strategy leads to faster and more stable threshold tests providing improved diagnostic capabilities. Besides the standard field indices the OCULUS Easyfield® delivers evaluations of the innovative Glaucoma Staging Program (GSP) and the classifications provided by the Glaucoma Staging System (GSS 2).


  • Fast: Shorter examination times even for threshold tests
  • Compact: No completely dark room required thanks to the closed construction
  • Lightweight: Minimal footprint and maximal transportability
  • Robust: Easy to service in the absence of moving parts
  • More than screening: Supra-threshold and threshold tests
  • Comprehensive perimetry: Advanced test strategies, unique evaluation tools, efficient progression analysis.

easyfield_c_Ergonomic Design

One of the most striking features of the OCULUS Easyfield® is its small footprint. Compact design and light-protected viewer enable examinations performed in rooms with normal lighting conditions. Its robustness and low weight make the OCULUS Easyfield® perimeter convenient for portable use. The absence of moving device parts guarantees prolonged product lifetime.



Eeasyfield_c_asy Operation

The OCULUS Easyfield® perimeter is operated via an external computer (notebook or PC). You can enjoy the full freedom of networking the examination data with the familiar user interface of the OCULUS programs. The use of translucent eye shields allows you to conduct measurements without the usual eye patch, thus saving you valuable time of preparing examinations.



easyfield_c_Increased Diagnostic Reliability

High stability test strategies like SPARK and additional assessment tools improve the diagnostic value of the OCULUS Easyfield® perimeter. The enhanced Glaucoma Staging System (GSS2) of Dr. Brusini and the Glaucoma Staging Program (GSP) expert systems offer extended support in the single field analysis. The Threshold Noiseless Trend (TNT) carries out efficient progression analysis. Examination quality is ensured by a patented fixation control algorithm, a high resolution video camera for eye monitoring and the various built-in catch trials.
