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 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. The reduction of light sensitivity, demonstrated in the results of Humphrey central 10-2 perimetry, is more apparent than visual acuity loss in eyes with central serous chorioretinopathy (CSC), in which patients complain of dimness in the visual field of the affected eye.

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.
This instrument is currently under evaluation for clinical use.) • Don't rely on only one of these instruments for a definitive diagnosis. In clinical practice, these fields are often obtained with office-based static automated perimetry such as the Humphrey visual field (HVF; Carl Zeiss Meditec).
