Humphrey field analyser (HFA) is a tool for measuring the human visual field that is commonly used by optometrists, orthoptists and ophthalmologists, particularly for detecting monocular visual field. The results of the analyser identify the type of vision defect. perimetry are not interchangeable. The Goldmann perimeter can also be used for manual static threshold perimetry, and other machines are also available for manual kinetic perimetry.

The progression of retinitis pigmentosa is well assssed with MD of Humphrey central 10-2 perimetry, which decreases Humphrey field analyser (HFA) is a tool for measuring the human visual field that is commonly used by optometrists, orthoptists and ophthalmologists, particularly for detecting monocular visual field.. The results of the analyser identify the type of vision defect. Therefore, it provides information regarding the location of any disease processes or lesion(s) throughout the visual pathway. Automated perimetry in both eyes with the Humphrey Field Analyzer SITA program 24-2 was used to measure the primary outcome variable. Each patient had at least two initial visual field exams at least 30 min apart to ensure reliability. Writing this 5th edition of the Humphrey primer has reminded us of just how much visual field testing has evolved since the days when we wrote each of the previous editions.

HFA3 delivers the interactive analysis you need, when and where you need it. Reduce visual field testing time with SITA™ Faster.; Central testing to view into the macula with SITA Faster 24-2C; Mixed Guided Progression Analysis™ (GPA™): intermixing of SITA Standard, SITA Fast and Background: The Humphrey field analyser (HFA), Humphrey-Zeiss frequency doubling perimeter, and the Medmont automated perimeter (MAP) are three commonly used automated perimeters with threshold achromatic methodologies. Visual field loss may be detected earlier with strategies that target cell lines with reduced redundancy or which suffer selective damage. 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.

At the present time, however, there is limited information available about the ability of this testing procedure to characterize the pattern and shape of visual field loss and to monitor progressive changes over time.

Perimetry is the systematic measurement of visual field function (the total area where objects can be seen in the peripheral vision while the eye is focused on a central point). The two most commonly used types of perimetry are Goldmann kinetic perimetry and threshold static automated perimetry.

At the present time, however, there is limited information available about the ability of this testing procedure to characterize the pattern and shape of visual field loss and to monitor progressive changes over time. Purpose: To evaluate and compare the diagnostic ability of frequency doubling technology perimetry (FDT) with standard automated perimetry (SAP) using Humphrey Field Analyser for the detection of visual field defects produced by chiasmal lesions.

Wong, MD, James A. Sharpe, MD Objective: To compare manual kinetic perimetry with tangent screen and Goldmann techniques and automated static perimetry with the Humphrey Field Analyzer in the detection and localization of occipital lobe lesions. Humphrey testing was first performed in 7 patients and Goldmann testing in 5 patients. Superior fields at the 12:00 meridian were 46° ± 6° taped, and 28° ± 12° untaped for Goldmann perimetry (P<.001, n = 24), and 38° ± 8° taped, and 24° ± 12° untaped for Humphrey perimetry (P<.001, n = 24) .
