What type of perimetry technique involves a moving target?

Confrontation testing
Goldmann perimetry
Kinetic perimetry
Static perimetry

The correct answer is: Kinetic perimetry

Kinetic perimetry is the type of perimetry technique that involves a moving target. In kinetic perimetry, the examiner manually moves a stimulus (such as a light) towards the patient's field of vision until the patient sees the stimulus and signals its detection. This type of perimetry is particularly useful in detecting the boundaries of the visual field and is often used in conditions such as glaucoma where peripheral vision loss may occur. Confrontation testing (Option A) involves the examiner comparing the patient's visual field to their own, without the use of a moving target. Goldmann perimetry (Option B) is a type of kinetic perimetry where the examiner manually moves a target of varying size and intensity to map the visual field. Static perimetry (Option D) involves presenting static stimuli at fixed locations in the visual field without movement of the target.
