Abstract
Krakau's automatic computerized perimeter has been used as the single perimetric instrument in 114 of 235 consecutive neuro-ophthalmological examinations. i.e. in 49%. It has several advantages over manual methods: (1) The perimetrist's errors are eliminated. (2) The stimuli are presented at random, so the patient cannot anticipate where the next stimulus will appear. (3) The exposure time of the stimuli is constant and the examination time fairly constant. (4) The results are obtained in numerical form, suitable for statistical evaluation. These advantages make the instrument superior to Goldmann's kinetic perimeter not only in detecting but also in following up neurological field defects. A disadvantage is the small central area examined, which renders the topical diagnosis more difficult than it is with Goldmann's perimeter.
