The Oculus Easyfield is an exciting compact perimeter to do static perimetry up to 30°. It has been designed for the combined use as a visual field screener and perimeter, offering features usually available only in large units. The Easyfield’s integrated bowl with a 11.81” (30 cm) radius and distance corrected lens is adapted to the Goldman standard and fulfills the ISO-norm 12866 for perimeters. The Easyfield has a fixed point grid with 135 test locations including 30-2. The unit offers various testing methods including: · Fast Threshold (3 minutes) · Normal Threshold (6 minutes), and · Supra-threshold with numerous testing strategies. Portable automated perimetry devices play an important role in glaucoma screening; by design they function reliably even outside of traditional eye clinics, reaching out, therefore, to an increased number of patients.
perimeter.
The Easyfield comes with a set of predefined programs for most frequently needed examination routines of the central visual field or the macular area. The program list can be easily extended according to specific requirements by combining the available test patterns and test strategies.
As a screening unit, the Easyfield® perimeter generally uses threshold related suprathreshold examination strategies. These have the advantage of providing the examiner with a meaningful overview of the tested area despite the short examination time. Multiple test strategies are available for evaluating the accurate numeric values of the sensitivity thresholds. The OCULUS "Fast Threshold" reduces test duration by implementing clever improvements of the classic 4-2 step method. The CLIP strategy achieves a similar performance using a new type of stimulus presentation. The novel and unique SPARK strategy provides rapid and reproducible threshold measurements specifically developed for glaucoma patients

OCULUS Test Patterns

The fixed grid of light emitting diodes of the Easyfield® perimeter allows examination of the common 30-2, 24-2 or 10-2 patterns. It is also possible to test individual hemispheres or quadrants. If necessary, any combination of individual points can be examined. The modular structure of the test programs allows for all patterns to be examined using any available standard strategy.
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 is shown in distinct depictions.

Moreover, they can be successfully used in regions with poor medical coverage or in mobile screening stations.
