Which type of perimetry technique involves a moving target?

The kinetic perimetry technique is characterized by the use of a moving target to assess a person's visual field. In this method, a stimulus (often a light) starts outside the typical visual field and is moved toward the center. The patient signals when they first perceive the light. This technique is useful for identifying the boundaries of vision and can be particularly effective in detecting peripheral vision loss.

Kinetic perimetry allows for a more dynamic assessment of visual fields compared to static methods, where the target remains fixed at specific locations. The movement of the target helps in evaluating the patient's ability to detect stimuli at various points in their visual field as it encroaches on their area of sight.

The other techniques mentioned, such as static perimetry, use stimuli that are stationary, while threshold perimetry focuses on determining the minimum intensity of light that a person can detect at various points. Automated perimetry incorporates technology to perform the tests but does not inherently involve moving targets in the sense that kinetic perimetry does.
