Automated system for testing visual fields

An electronic system for automatically testing the human visual field is described in the context of mass screening for visual disorders, such as glaucoma. Present methods of field testing are briefly reviewed. The new system is patient operated and uses a television monitor as the means for presenting the test stimuli and displaying the results. A multilevel map of a patient´s retinal sensitivity is produced in a form which is readily interpreted by an ophthalmologist. A data-transfer unit enables the local storage of results and allows direct access to a computer. Preliminary clinical trials show good agreement with conventional field-testing methods, and yield more detailed information than has hitherto been feasible on a routine basis.
