Humpheries Perimeter Exam

PageImage127381Automated (computerized) field analyzers, such as the Humphrey or the Octopus perimeters are used to perform the field of vision test. A light point is presented in a predetermined fashion (location sequence) in a lighted bowl and
the patient is asked to press a button when they see the light point. The
responses are analyzed statistically and compared with a database of normal responses. Any deviations from normal are marked on a printout as black squares which represent visual field-defect areas.
