What type of perimetry technique involves a moving target?

The type of perimetry technique that involves a moving target is kinetic perimetry. This method is designed to map the visual field by utilizing a target that moves across the visual field, allowing the examiner to determine the point at which the patient first perceives the moving stimulus.

Kinetic perimetry is effective in assessing dynamic aspects of vision and can provide valuable information regarding the extent of the visual field and any potential defects. The movement of the target, typically a light or an object, helps in identifying areas where vision might be lost or diminished.

In contrast, static perimetry presents targets of fixed luminance at various locations in the visual field to assess sensitivity without movement. Automated perimetry employs computerized methods to present stimuli, and threshold perimetry typically refers to techniques used to determine the minimum level of brightness a person can perceive in various areas of their visual field, often utilizing stationary stimuli. These approaches differ from kinetic perimetry in their mechanics and the type of information they provide about a patient’s visual field.
