How should we test visual acuity in terms quadrants?

• A. In the Central Field Only
• B. In the Superior Quadrants Only
• C. In the Left Half of the Visual Field
• D. In All Four Quadrants

Answer: (D)

Testing visual acuity across the entire field ensures you don’t miss a deficit in any part of what the patient uses in daily life. Central vision is the sharpest, but acuity can vary in different parts of the visual field due to disease, injury, or scotomas. By evaluating all four quadrants, you get a complete picture of how clearly the patient sees in each region, which is crucial for planning rehabilitation strategies such as scanning training, appropriate lighting, or adaptive methods for field loss. If you only test the central field or just one half, you risk overlooking problems in other areas that can impact real-world function.
