Testing Procedure - Visual Fields (Confrontation Testing)

The patient's visual field will be compared with that of the examiner. The clinician sits facing the patient and instructs the patient to focus on the tip of the therapist’s nose, while the therapist focuses on the patient's nose. The clinician slowly moves his or her fingers bilaterally from a lateral position to a medial position, while maintaining an arc of approximately 12 to 16 inches from the patient's head. The clinician continues to move in a slow and controlled manner until the patient is able to identify the stimulus finger. The patient is instructed to state “right” or “left,” or point to the finger when it is first identified in a given visual field, as pictured to the right. If the patient has difficulty identifying the therapist's finger, the clinician can wiggle his or her fingers. When the patient reports that he or she can see the therapist's finger or object, the field of vision is compared to that of the therapist, as well as expected findings. Tests are repeated for upper and lower visual fields in a similar manner. Document normal or abnormal responses.
