It is most commonly performed on an automated perimeter (often called a Humphrey Field Analyzer). Clinics use it to map areas of reduced sensitivity that may not be noticeable in everyday vision. It is widely used in ophthalmology and optometry, especially for glaucoma and neuro-ophthalmology evaluations."}
