In which sequential order would the nurse assess the visual field of a client?

• A. Direct client to stand 60 cm away from eye level; ask client to close his or her right eye gently; close opposite eye to superimpose field of vision; move finger equidistant between nurse and client; ask client to report when they see finger
• B. Move finger equidistant between nurse and client; direct client to stand 60 cm away from eye level; ask client to report when they see finger; ask client to close right eye gently; close opposite eye to superimpose field of vision
• C. Ask client to report when they see finger; move finger equidistant between nurse and client; direct client to stand 60 cm away from eye level; ask client to close right eye gently; close opposite eye to superimpose field of vision
• D. Ask client to close his or her right eye gently; close opposite eye to superimpose field of vision; move finger equidistant between nurse and client; ask client to report when they see finger

Answer: (A)

Testing the visual field with confrontation relies on establishing a fixed distance and gaze, isolating one eye, and then presenting a peripheral stimulus toward the center so the patient can report when it first becomes visible. Start by positioning the client about 60 cm away and have them fix their gaze on a stable point. Then occlude the eye to be tested while the opposite eye is also covered to prevent the untested eye from compensating. Next, bring a finger in from the periphery, keeping it equidistant between you and the client, and ask the client to say when they first see it. This sequence ensures the stimulus is presented consistently and that only the intended eye’s field is being measured. Moving the finger before establishing the distance or occluding the eyes could cause incorrect findings, and asking for a response before the finger is in view would yield unreliable results.
