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 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).

ryan tourt Peristat online perimetry at detecting varying degrees of glaucoma and the correlation between Peristat online perimetry and Humphrey visual field. Methods: A prospective, comparative study of Peristat online perimetry (an achromatic static computer threshold testing program) and Humphrey visual field (HealthDay)—A simple static perimetry approach may yield higher-quality results than a combined perimetry approach in children younger than 10 years with glaucoma, according to a study published Another worthy competitor for Goldmann perimetry, is the Humphrey field analyzer 3. Besides static perimetry, the HFA3 also offers a kinetic mode.

With threshold static automated perimetry, a computer program is selected. The most commonly used one tests the central 30° of the visual field using a six degree spaced grid. This is accomplished by keeping the size and location of a target constant and varying the brightness until the dimmest target the patient can see at each of the test locations is found.

Whether foveal Static perimetry is a visual field testing method, which determines the retinal sensitivity by Some other perimeters, such as the Humphrey and Digilab, do not. Automated static perimetry.

The Humphrey field analyser is by far the most commonly used for automated static perimetry, although there are also other machines such as Octopus and Henson.

In static perimetry, stationary stimuli are presented at defined points in the visual field. Stimuli presented for longer durations of time may be seen better as a result of temporal summation of information, though limited additional benefit is derived beyond times over 1/10th of a second.

Static perimetry, of which there are several versions, uses a computer algorithm to present targets at fixed locations to delineate scotomas in a more expedited fashion. A full discussion of the differences between static and kinetic perimetry is beyond the scope of this column, however, those interested are encouraged to explore the suggested reading at the end of this article.

Static How to use the information in the standard charts produced as part of automated static threshold perimetry to determine whether the visual field test satisfies our requirements. To illustrate this, we refer to standard charts produced by the Humphrey Field Analyzer. PURPOSE: Static fixation is the standard method for stabilizing the eye during automated perimetry. Kinetic fixation is an alternative for fixation control in which the eye follows a moving target.

It found the most commonly used static perimetry programs to be the 30–2 and 24–2 on the Humphrey II-i, both of which assess the central visual field. By only assessing the central visual field, the detection of any defects beyond these boundaries is limited, reducing diagnostic accuracy in some conditions where the peripheral visual field is affected first ( Khoury et al. 1999 ; Rowe et
