Eye Specialists Employ Multiple Tests to Map Visual Fields

Eye specialists use various methods to assess visual fields, crucial for detecting peripheral vision issues. These tests help identify problems caused by eye disorders or central nervous system issues.

The confrontational visual field exam is a simple, manual test. A doctor moves their hand in and out of the patient's field of view, with the patient indicating when they see it. For a more precise and automated approach, the tangent screen test uses a computer screen to generate images in different visual field areas. During this exam, static perimetry, kinetic perimetry, or frequency doubling technology (FDT) perimetry may be employed. These techniques help map the visual field by presenting small lights or moving targets and recording patient responses.

Visual field problems can stem from various causes, including glaucoma, macular degeneration, optic glioma, brain tumors, multiple sclerosis, stroke, and temporal arteritis. These tests aid in early detection and management of these conditions.

Eye specialists employ several methods, such as the confrontational visual field exam, tangent screen test, and automated perimetry exam, to assess visual fields. These tests help identify peripheral vision issues, enabling timely diagnosis and treatment of underlying conditions like glaucoma or brain tumors.
