What is the key to starting the VR examination?

• A. Comprehensive history taking only
• B. Ocular motility screening first
• C. Color vision testing first
• D. Refractive analysis, should be done from scratch

Answer: (D)

Starting with a fresh refractive analysis done from scratch sets the baseline for the entire vision rehabilitation process. Knowing the current refractive status precisely determines how much a patient’s acuity can improve with correction and guides decisions about glasses, contact lenses, or device use. If you rely on prior prescriptions or assumptions, you risk carrying forward outdated or inappropriate corrections, which can skew functional assessments and lead to ineffective rehabilitation plans. With an accurate refractive starting point, you can interpret the patient’s goals, plan appropriate training, and select aids that truly maximize usable vision. While gathering history and checking ocular health or motility are important, they don’t provide the crucial foundational correction data that shapes the rest of the VR plan.
