15 cze 2020 · Visual field (VF) testing, although sometimes described as “torturous” by our patients, can be gratifying (and important) to interpret as an ophthalmologist, especially when done systematically. This article provides quick pearls and a framework by which you can conquer interpretation of VFs and points you in the direction of relevant ...
To determine normal values of the visual field (VF), corrected for age and reaction time (RT) for semiautomated kinetic perimetry (SKP) on the Octopus 900 perimeter, create a model describing the age-dependency of these values, and assess test–retest reliability for each isopter.
23 kwi 2024 · Accurately tested visual fields (VFs) provide clues to several ophthalmological and neurological diseases. The VF test is the most commonly performed clinical diagnostic test for the evaluation of extrafoveal visual function for the diagnosis and monitoring of neuro-retinal diseases [1].
20 cze 2020 · Kinetic perimetry involves a moving stimulus, where sensitivity thresholds are determined by moving stimuli of various sizes and light intensities from a non-seeing area of the visual field into a seeing area. The trajectory of the stimulus is called a vector. The location where the light is seen is then recorded.
30 sty 2024 · In kinetic perimetry, a specified visual stimulus is moved (kinetic) inside of a customized hemispheric bowl from a non-seeing to a seeing area in various meridians in order to identify isopters—defined as lines that connect points of similar visual threshold.
1 mar 2021 · Although VF testing consists of various methods, such as tangent screen, kinetic perimetry, and static perimetry, standard automated perimetry (SAP) is the gold standard method used for glaucoma management.
Kinetic perimetry uses a moving illumi-nated target and is done either manually (eg, Goldmann) or on an automated machine (eg, Octopus). Goldmann machines are no longer manufactured, being slowly replaced by Octopus machines.
