Automation of perimetry is quite feasible in normal subjects (3.6 % failures). It is equally feasible in patients with visual field defects not over 60 years of age (0 % failures). Automated examination ends in failure in 30 % of the patients in the older age groups seen in our clinic. This means that automated perimetry is particularly suitable for purposes of screening, i.e. to distinguish between subjects with and without visual field defects. Automated perimetry also allows performance of an accurate assessment phase, but in 16 % of the cases the examination will have to be performed by a perimetrist. To a center for perimetry, this still means a considerable lightening the work load. In general, automation of perimetry means that the possibility of examination of the visual field is made available to large groups of people.
