What type of perimetry technique involves a moving target?

The perimetry technique that involves a moving target is kinetic perimetry. This method assesses the visual field by presenting stimuli that move from an area of non-visibility to an area of visibility. The examiner moves a light (or other stimulus) across the visual field, and the patient indicates when they can see the stimulus. This allows clinicians to map out the boundaries of the patient's visual field and detect any areas of vision loss.

Kinetic perimetry is particularly useful for identifying scotomas—regions of partial or complete vision loss. The movement of the target helps to gauge the threshold of perception at different points in the visual field, which can be beneficial in diagnosing and monitoring various eye conditions.

In contrast, static perimetry presents fixed points of light at varying intensities without movement, while threshold perimetry is more focused on determining the minimum stimulus needed to elicit a response at specific points. Visual evoked potential testing, on the other hand, measures the electrical activity in the brain in response to visual stimuli rather than assessing the visual field directly.
