# DDD Visual Field Static Perimetry Use Cases (Informative)

## DDD.1 Introduction

Automated visual fields are the most commonly used method to assess the function of the visual system. This is accomplished by sequentially presenting visual stimuli to the patient and then requiring the patient press a button if he/she perceives a stimulus. The stimuli are presented at a variety of points within the area expected to be visible to the patient and each of those points is tested with multiple stimuli of varying intensity. The result of this is a spatial map indicating how well the patient can see throughout his/her visual field.
