Overview
The OCULUS Easyfield C is an exciting new 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 Goldmann standard and fulfills the ISO-norm 12866 for perimeters.
The Easyfield C has a fixed point grid with 135 test locations including 30-2.
Features
Static Perimetry
Numerous threshold strategies, supraliminal and user-defined programs.
Kinetic Perimetry
Automatic examinations on pre-programmed or user-defined meridians.
Colour Perimetry
A blue stimulus on a yellow background can be presented in static and kinetic perimetry.
Goldmann Standard
Stimulus luminance and size correspond to the Goldmann Standard in static and kinetic perimetry.
CLIP-Strategy
CLIP = continuous light incremented perimetry
The unique real threshold test that outperforms most interpolation based algorithms.
