Guide To Diagnosing And Treating Cataracts

Visual Field Test

Cataracts can be detected with the use of a visual field test. As discussed, the width of an area that can be seen by the eye when it is focused on a central point is considered the visual field. A confrontation visual field test is the manual method used to test the accuracy of the patient's peripheral visual field. An automated perimetry test is a visual field test performed with the use of a machine called a perimeter that can show the provider a detailed map of where a patient can and cannot see. Cataracts can compromise a patient's ability to see clearly and accurately in certain parts of the eye. The peripheral vision is commonly affected by the development of cataracts in the eye, and a visual field test can pick up this type of compromised functionality.
