What is the purpose of the visual fields test (confrontation test) as described in the chapter on eye disorders?

The purpose of the visual fields test, also known as the confrontation test, is to examine the patient's visual fields and detect problems with peripheral vision.

During the visual fields test, the examiner faces the patient and asks them to look directly into their eyes while covering one eye. The examiner then moves a finger from outside the patient's peripheral vision into their line of sight. The patient should detect the finger at the same time as the examiner. This test is repeated for the other eye to ensure a comprehensive assessment of visual field integrity.
