All perimeters measure sensitivity to stimuli at multiple locations in the visual field, though multiple variables define the perimeter. Effective Perimetry (Zeiss Visual Field Primer, 4th Edition. Heijl, Bengtsson & Patella, 2012) Perimetry has long been an important tool for identifying visual field defects and guiding glaucoma patients' treatment. Kinetic perimetry involves the use of moving targets from nonseeing to seeing areas to delineate spots of decreased or absent vision.

Kinetic perimetry: Typical example is the Goldmannn perimetry and the test is performed actively by an examiner physically moving the target on the arc and bowl perimeter with the patient reciprocating on visualization of a test object. Most importantly the intensity of the test stimulus cannot be varied but the color and the size can be modified.
