What is diplopia mapping used for in ABV?

• A. To assess refractive error
• B. To measure accommodation
• C. To determine ocular motility speed
• D. To map the diplopia field to identify alignment and plan therapy

Answer: (D)

Diplopia mapping in ABV is about charting where double vision appears across different gaze positions to understand how the eyes are misaligned. By mapping the diplopic field, you can see whether the misalignment is constant or changes with direction, which eyes the diplopia is seen in, and how severe it is in each area of the visual field. This information directly guides alignment-focused therapy, such as prism prescriptions and targeted binocular rehabilitation, and helps plan further interventions if needed. It’s not used to measure refractive error, assess accommodation, or determine how quickly the eyes move; those functions are addressed by separate tests.
