The normal visual field on the Humphrey field analyzer.

Ophthalmologica, 1986
To provide a bank of normal perimetric data, we tested the central and peripheral visual fields of 102 novice normal subjects using the Humphrey automated perimeter. All eyes used for visual field testing were first carefully examined to be sure that they were, indeed, normal. We calculated population means and standard deviations of each test location

A multicenter comparison study of the Humphrey Field Analyzer I and the Humphrey Field Analyzer II.

Ophthalmology, 1997
The purpose of the study is to determine the comparability of the 30-2 full-threshold program in the original Humphrey Field Analyzer (HFA) I to the same test procedure in the new Humphrey Field Analyzer II.At each of five clinical centers, one eye of patients with ocular hypertension and normal visual fields, patients with early glaucomatous visual ...

Macular integrity assessment microperimetry, Humphrey field analyzer, and spectral-domain optical coherence tomography in glaucoma practice: a correlation study of functional and structural parameters.

Canadian Journal of Ophthalmology-journal Canadien D Ophtalmologie, 2021
OBJECTIVE To compare and correlate retinal sensitivities measured with macular integrity assessment microperimetry (MAIA-MP) and Humphrey field analyzer (HFA) 10-2 tests with structural parameters obtained from optical coherence tomography (OCT) in ...

Peripheral Visual Field Thresholds using Humphrey Field Analyzer Program 60–4 in Normal Eyes

European Journal of Ophthalmology, 2011
Purpose Various methods have been used for testing peripheral visual field disturbances such as defects caused by drug toxicity. 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 ...

Peripheral visual field testing in glaucoma by automated kinetic perimetry with the Humphrey Field Analyzer.

Archives of Ophthalmology, 1992
A Humphrey automated perimeter was used to measure the central 24 degrees of vision with static threshold targets and the peripheral field with two automatic kinetic stimuli in 100 eyes of 100 patients with glaucoma or a suspicion of glaucoma and to compare the additional information gained with the peripheral tests.

Comparing the Performance of Compass Perimetry With Humphrey Field Analyzer in Eyes With Glaucoma

Journal of Glaucoma, 2017
Purpose: To evaluate the reliability indices [fixation losses, false negative response rates (FN) and false positive response rates] and threshold sensitivities obtained from glaucoma patients with a Compass perimeter and to compare the same with the Humphrey field analyzer (HFA). Methods:

Preliminary Clinical Trials with the Humphrey Field Analyzer

1985
The 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.
