Preliminary Clinical Trials with the Humphrey Field Analyzer
1985The Humphrey Field Analyzer is a new automated perimeter that performs static threshold testing and suprathreshold static testing. The static threshold test procedures use a target presentation pattern and staircase testing strategy that is similar to those employed on the Octopus and Squid automated perimeters.

Development of a Visual Field Screening Test Using a Humphrey Visual Field Analyzer
1985Field test results were compared between the Octopus Perimeter and the Humphrey Automated Field Analyzer. Slopes were noted to be steeper in the superior than the inferior field. The authors found approximately 4 dB higher threshold sensitivity in the Humphrey than in the Octopus. This is probably due to variation in stimulus exposure time, 0.2 seconds

Comparison of a Novel Head-mounted Perimeter vs. the Humphrey Field Analyzer
Ophthalmology GlaucomaPerimetry is a critical tool for the diagnosis and monitoring of glaucomatous visual field defects. The Humphrey Field Analyzer (HFA) is a large, relatively expensive device that does not normally allow for examination outside of the clinic, and it can be ergonomically difficult to tolerate for some patients.

A system for the analysis of automated visual fields using the Humphrey Visual Field Analyzer
1987Analyzing visual field progression is an important component of glaucoma management. Unfortunately, detecting progression reliably may be difficult. Factors such as short-term (intratest) and long-term (intertest) fluctuation, patient fatigue, patient learning curve, etc., can cause transient visual field changes which may mimic improvement or ...

To evaluate the accuracy of the visual field index (VFI) for the Humphrey Visual Field Analyzer in a population of patients with mild to moderate glaucoma.Retrospective cohort study.The study included 42 patients (61 eyes) with at least 11 years of follow-up, and annual automated visual fields (VFs). Patients with mean deviations ≤-20 dB were excluded.

Glaucoma is a disease affecting the optic nerve. Structural as well as functional changes occur as the disease progresses. Glaucomatous optic discs appear with certain patterns of structural damage, and the disease’s main consequence is patient’s visual field damage.

We examined the correlation between the visual field index (VFI) and mean deviation (MD), as well as the correlation on VFI slope and MD slope.This retrospective study was performed on 105 eyes of 60 patients. All eyes underwent examination by the Humphrey visual field analyzer.
