In the same visual field testing sequence, which step comes last?

• A. Direct client to stand 60 cm away from eye level
• B. Ask client to close the right eye gently
• C. Close opposite eye to superimpose field of vision
• D. Ask client to report when they see finger

Answer: (D)

In visual field testing, the sequence builds from setup to data collection. First, you position the patient at the correct distance and level so the target is tested from a standardized position. Then you isolate the eye being tested by closing or covering the other eye, ensuring that responses come from the same eye across the field. After the eye is prepared, you introduce stimuli into the peripheral fields and rely on the patient to indicate when they notice them. That perceptual reporting is what records the actual boundary of their field of vision for that eye. Therefore, the step where the patient is asked to report when they see the finger is the last action because it provides the essential data about their visual field. The preceding steps are important setup, but they don’t by themselves yield the perceptual boundary; that final report does.
