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.

Here, we’ll only talk about the Humphrey visual field perimeter, which is used for 99% of visual field tests. It’s an automated, static perimeter (unlike Goldmann kinetic perimetry which requires a human operator, and uses a moving target). The Humphrey uses fixed points of light which are shown at different intensity levels.

INDICATIONS OF PERIMETRY • Detection of glaucoma, progression • Chorioretinal lesions • Optic disc and optic nerve lesions • Neuro-ophthalmological diseases 7.

Heijl, Bengtsson & Patella, 2012) Offers reports similar to those of the Humphrey HFA, the World Standard of Care. * Using DICOM, or you can export JPEG or PDF files via the USB port to a PC or EHR. ** Trial lenses are required beyond +/-3 diopters for the Humphrey Matrix and beyond +/-7 diopters for the Humphrey FDT. 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.

Method: Full-threshold data (Humphrey Visual Field Analyzer (HFA) Program 30-2) from a normal database (n=146) and a POAG database (n=69) were analyzed to establish the precision of both an age-related and the HFA threshold-related technique for deriving the test intensity in suprathreshold perimetry.
