    OCULUS Easyfield® Automated Perimeter

    Price:  $0.00

    OCULUS Easyfield®

    The OCULUS Easyfield®

    is the smallest full-fledged perimeter on the market. It is designed for use as a visual field screener and as a threshold perimeter for
    immediate re-examination of any abnormal findings. Ideal for all common examinations of the central visual field up to 30°.
    The Easyfield® C has an adjustable double chin rest and uses translucent eye shields for maximum patient comfort.


    Ergonomic Design

    Easy Operation

    The 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.


    OCULUS 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.

    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.

    The Spark strategy uses the correlation between different points in Glaucomatous visual fields to considerably expedite the examination

    Glaucoma Staging Program (GSP)The Glaucoma Staging Program (GSP) is based on pattern recognition and is dedicated to early detection of glaucoma. The GSP software places examination findings into visual field classes (normal, glaucomatous, artifactual and neuro) based solely on their appearance. In addition, risk classes (normal, suspect, pre-perimetric, early stage, moderate and severe) are also assigned to findings that are classified as normal or glaucomatous. The evaluation results are presented in intuitive green-yellow-red color coding. The striking novelty of the GSP is its ability to detect subtle changes in the visual field associated with early stage glaucoma. Findings of suspect and pre-perimetric risk classes may contain reductions in the visual field that cannot be readily seen by the examiner. They usually remain undetected also by standard perimetric indices.
    The Glaucoma Likelihood Index (GLI) summarizes the results of the GSP classification into a single parameter presenting a value between 0 (normal) and 5 (severe glaucoma).
    The Glaucoma Staging Program (GSP) is available for OCULUS  Twinfield® 2, Centerfield® 2 and Easyfield® Perimeters.  This upgrade is available for the existing units.
