What is the order of steps in a gross visual acuity testing sequence?

• A. Count fingers, detect hand motion, light perception
• B. Use a near card, count fingers, assess light perception
• C. Token tests, object recognition, light sensitivity
• D. Ask for symptoms, followed by light tests

Answer: (B)

The correct answer outlines a structured approach to assessing visual acuity, which is essential for determining the level of vision and any potential issues affecting a patient's eyesight. Using a near card allows the medic to evaluate how well a patient can see at a close distance, which is especially useful for detecting issues with near vision. This step establishes a baseline for the patient's visual capabilities. Following this, counting fingers provides a more specific measurement of visual acuity at a distance, allowing for a quantitative assessment of how well a patient can perceive objects. Finally, assessing light perception is crucial for understanding the extent of the patient's vision and determining if they can perceive light, which is an important indicator of eye health. This sequence logically progresses from detailed testing of close vision to broader assessments and eliminates uncertainty about a patient’s overall visual function. The other options do not follow this logical progression or include steps that may not be relevant to standard visual acuity testing.
