Van Orden Star: Which statement is true?

Van Orden Star: Which statement is true?

• A. Measures color perception
• B. Determines the quality of binocular posture when there is bilateral manual involvement.
• C. Yields 87 mm separation
• D. Is not used clinically

Answer: (B)

The test is used to judge how well the eyes work together during a task that involves motor activity with both hands. In the Van Orden star setup, the patient must maintain proper binocular alignment while actively guiding or manipulating a star-like stimulus with both hands. This directly measures the quality of binocular posture under bilateral manual load, so that statement captures the purpose of the test most accurately. Color perception is assessed with separate color-vision tests, not this star setup. The result isn’t a fixed distance like 87 mm—it's about how stably the eyes maintain alignment under the task. And the Van Orden star is a clinical tool, not something obsolete.
