WebFeb 27, 2024 · A variety of sensitive tests for measuring visual field loss exist, including: Automated Perimetry. Various forms of automated perimetry tests measure your responses to the presence of objects in different areas of your field of view. WebMar 12, 2024 · Standard automated perimetry has been the gold standard for evaluating a patient’s visual field for many years. The information it provides is crucial to monitoring the status of our glaucoma patients, and it often allows us to detect functional deficits before an individual notices any loss.
WebPerimetry and visual field testing have been used as clinical ophthalmic diagnostic tools for many years, and this manuscript will provide a brief historical overview of these procedures and the individuals who developed them.
