How does sensory fusion grading inform ABV management?

• A. It quantifies the level of fusion and guides therapy decisions
• B. It measures refractive error
• C. It predicts diplopia intensity in all conditions
• D. It assesses ocular motility speed

Answer: (A)

Sensory fusion grading tells you how well the brain is fusing images from both eyes and whether suppression is present. That information directly guides ABV management because it shows what the patient can or cannot fuse under binocular demand, which in turn determines the therapeutic approach. If fusion is robust, you emphasize maintaining binocular function and fine-tuning vergence with targeted practice, since the system already handles fusion well. If fusion is partial or suppressed in some viewing positions, therapy aims to reduce suppression and strengthen fusional reserves, often using binocular/dichoptic training, graded visual tasks, or prism strategies to realign images so fusion becomes more reliable. The grade also helps track progress and inform decisions about increasing therapy intensity or adjusting the plan. Refractive error measurement is a separate domain focused on optics, not on how the brain combines two images. Predicting diplopia intensity in all conditions isn’t reliable from fusion grade alone, as diplopia depends on gaze angle, alignment, and other factors. Ocular motility speed concerns how the eyes move, not how their images are fused in perception.
