What is a common objective of ABV testing battery?

• A. To determine phorias, vergence ranges, accommodation function, suppression, and stereoacuity to guide treatment
• B. To measure color vision
• C. To test only near points
• D. To assess ocular health only

Answer: (A)

At its heart, ABV testing battery is about evaluating how the eyes work together as a functional unit. It assesses the main aspects of binocular vision that determine how well a person can align the eyes, maintain that alignment across turning gaze from far to near, and fuse the images into a single, stable view. Specifically, it looks at: phorias, which reveal latent misalignment when binocular fusion is disrupted; vergence ranges, which show fusional reserves for both convergence and divergence to maintain single vision as eye position changes; accommodation function, which tests how well focusing interacts with vergence and whether focusing demands are met smoothly; suppression, which detects when one eye’s input is being suppressed to avoid diplopia; and stereoacuity, which measures fine depth perception resulting from proper binocular cooperation. Together, these components guide treatment decisions—such as prism correction, vision therapy to enhance vergence or accommodation, or strategies to address suppression or depth perception issues. Other options miss this broad, integrated focus. Measuring color vision, testing only near points, or assessing ocular health in isolation do not capture the full range of binocular function the ABV battery aims to evaluate to inform management.
