Family Nurse Practitioner Exam

What is the purpose of the visual fields by confrontation test?

1. A) Evaluate peripheral vision

2. B) Measure central distance vision

3. C) Assess for narrow-angle glaucoma

4. D) Test accommodation

The correct answer is: A) Evaluate peripheral vision

The purpose of the visual fields by confrontation test is to evaluate peripheral vision. This test involves the examiner and patient facing each other at eye level, with the patient covering one eye while the examiner presents visual stimuli from the periphery. The patient is then asked to indicate when they can see the examiner's hand or object entering their peripheral vision. This method is effective in detecting any abnormalities in the visual field, such as blind spots or loss of peripheral vision, which can indicate various conditions, including glaucoma, retinal detachment, or neurological issues affecting the optic pathways. In contrast, other options focus on different aspects of vision. Measuring central distance vision pertains to assessing clarity of vision at a distance, while assessing for narrow-angle glaucoma and testing accommodation involve specific clinical methods and instruments rather than a simple confrontation visual test.
