Maximizing Early Detection: Understanding the Visual Field Test for Peripheral Vision Assessment

what method is used to assess peripheral vision?

The method that is generally used to assess peripheral vision is the visual field test. Visual field test is a diagnostic tool used to determine the entire scope of human sight, from the central vision out to the periphery. During visual field testing, the patient is seated in front of a hemispheric screen, and a series of lights or other stimuli are presented in different areas of the screen. The patient is asked to indicate when they see the stimuli by pressing a button or raising their hand. This test determines the areas where the patient can and cannot see, allowing the doctor to assess the function of the patient’s peripheral vision. Different types of visual field tests are available, such as the Humphrey Visual Field test, Goldmann perimeter test, and tangent screen test, and the choice of test can vary depending on the patient’s specific condition and the preference of the examiner.
