Kinetic perimetry Static perimetry Measures the extent of visual field by plotting the isopters Measures the sensitivity of each retinal points Stimulus moves from non seeing to seeing area Stimulus is stationary but increases in luminance until seen Stimulus size can be varied Constant 2D measurement of hill of vision 3D assessment of height of predetermined areas of hill of vision 5/3/2014 32 Since, in most eyes with retinal diseases quality of vision is greatly affected by visual field defects including paracentral scotoma and inferior field defects, visual function should be assessed by central 30- or 10-degrree automated static perimetry as well as visual acuity testing. The reduction of light sensitivity, demonstrated in the results of Humphrey central 10-2 perimetry, is more 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 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. This study was conducted to evaluate the fixation accuracy of static and kinetic fixation perimetry and to determine their ability to detect the absolute scotoma of the physiologic blind spot. 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.
In clinical practice, these fields are often obtained with office-based static automated perimetry such as the Humphrey visual field (HVF; Carl Zeiss Meditec). The machines are relatively costly, however, so the examinations are generally performed in doctors’ offices.
Automated static threshold perimetry measures the retina's sensitivity to light at predetermined locations in the visual field. While the individual focuses on a specific point, called the point of fixation , stimuli are presented in random order at each of the predetermined locations within the visual field.

The Humphrey uses fixed points of light which are shown at different intensity levels. Goldmann kinetic and Humphrey static perimetry results are not amenable to quantitative comparisons because of the different formats of data produced by each device. The Goldmann perimeter produces a circular isopter on a polar coordinate grid and the Humphrey perimeter produces a discreet grid of logarithmic sensitivities with x-y coordinates 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 The Octopus perimeter, the Humphrey Field Analyzer, and Humphrey Matrix are a few of the available automated perimeters. Although the Octopus can perform a modified kinetic perimetry, most automated perimetry is static: stationary stimuli, varying in size and intensity, are presented in specific locations within the visual field [6].
