The OCULUS Easyfield® is designed for use as a visual field screener and a threshold perimeter for immediate re-examination of any abnormal findings. Full compliance with Goldman Standards makes the Easyfield® ideal for all common examinations of the central field of vision up to 30°. The Easyfield® C has an adjustable double chin rest and eye shields for maximum patient comfort.
The Glaucoma Staging System (GSS 2) per Brusini classifies visual field defects based on the perimetric indices MD (Mean Deviation) and PSD (Pattern Standard Deviation). The representative point of the examination is placed in a chart in accordance with the values of these indices. The chart shows defined areas for the different stages of disease (Stage 0 - Stage 5). It also separates generalized, localized and mixed defects.
