The Humphrey FDT® is from Carl Zeiss Meditec, the world leader in diagnostic test equipment for ophthalmology. Carl Zeiss Meditec is also the developer and distributor of the Humphrey® Field Analyzer, the recognized gold standard in visual field testing. Humphrey Field Analyzers are used by more eye

The results of the analyser identify the type of vision defect. For the Humphrey perimeter, a test stimulus of 4 mm 2 (corresponding to a Goldmann size III stimulus) is most commonly used, though larger stimulus sizes may be employed for individuals with poor visual acuity. The Humphrey perimeter tests light intensities over 5 orders of magnitudes, from 10,000 apostilbs (asb) to 0.1 asb. Perimetry 1 1.

Humphrey perimetry test duration was generally longer than Octopus SKP. In the absence of kinetic perimetry, peripheral static suprathreshold programme options such as FF120 may be useful for detection of visual field defects. However, statokinetic dissociation may occur.

Methods. Prospective cross-section study comparing Humphrey full field (FF) 120 two zone programme to a screening protocol for SKP on Octopus perimetry. Humphrey Perimetry, supplied by Carl Zeiss, used in various techniques.

Static threshold perimetry with Humphrey Field Analyzer (HFA) is widely available. The aim of this study was to better define the normal thresholds for peripheral visual field (PVF) sensitivity and to refine analysis strategies. Methods: Automated PVF testing was performed with HFA 60-4 program in 33 normal subjects.

The Humphrey uses fixed points of light which are shown at different intensity levels. Static perimetry, of which there are several versions, uses a computer algorithm to present targets at fixed locations to delineate scotomas in a more expedited fashion.
