Nott's method is a dynamic retinoscopy technique that determines what?

• A. The patient's distance vision
• B. The accommodation demand at which neutrality occurs
• C. The pupil diameter
• D. The refractive index of the cornea

Answer: (B)

Dynamic retinoscopy with Nott’s method focuses on how much accommodation the eye is using for a given near target. You observe the retinoscopic reflex as the patient looks at a near object and adjust the setup until the reflex becomes neutral. The distance (or lens power) at which neutrality occurs represents the accommodation demand of the eye for that near target. This tells you the amount of accommodation the patient must exert to see at that near distance, not the patient’s distance vision, pupil size, or corneal refractive index.
