Certified Paraoptometric (CPO) Practice Exam 2025

What part of the eye examination guides the tests during an office visit?

1. Case History

2. Visual Acuity

3. Prescription Estimate

4. Diagnostic Imaging

The correct answer is: Case History

The case history is crucial in guiding the tests conducted during an office visit for an eye examination. It involves gathering comprehensive information about the patient's medical and ocular history, including previous eye problems, current symptoms, systemic health issues, medication use, and family history of eye diseases. This information provides the optometrist or paraoptometric technician with the context necessary to tailor the examination process. By understanding the patient's concerns and medical background, the practitioner can prioritize specific tests and assessments, ensuring that the examination is relevant and efficient. Visual acuity, while essential in assessing the clarity of vision, is just one aspect of the examination and typically follows the gathering of a thorough case history. Prescription estimates are derived after examining visual acuity and overall eye health, and diagnostic imaging serves to support findings but does not guide the initial testing process as effectively as the case history does.
