Oculus Easyfield Visual Field Analyzer Perimeter

KEY FEATURES
– Full-fledged compact perimeter capable of performing standard automated perimetry of the central visual field up to 30° eccentricity

– Designed for the combined use as visual field screener and perimeter, offering features usually available only in large units

– Spherical bowl with 30 cm (11.81”) radius is enclosed into an ergonomically movable cone equipped with a distance adapted lens

– Conforms to the Goldmann standard and fulfills the ISO-12866 norm for perimeters

– Measurements of the Easyfield are carried out using an LED grid with 135 fixed test locations, including the common 30-2, 24-2 and 10-2 patterns

– Novel SPARK test strategy leads to faster and more stable threshold tests providing improved diagnostic capabilities

– Besides the standard field indices the Easyfield delivers evaluations of the innovative Glaucoma Staging Program (GSP) and the classifications provided by the Glaucoma Staging System

ADVANTAGES
– 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

– Full Threshold: The classical 4-2 dB staircase strategy using two reversals in the patient€™s answer to deliver a threshold value

– Fast Threshold: Bracketing strategy using variable steps and taking advantage of already measured locations

– CLIP: Strategy using stimuli with continuously increasing luminance

– Threshold value is assigned the moment the stimulus is perceived

– SPARK: Fast and averaged threshold strategy based on statistical correlations between threshold values measured in different locations
