Abstract
Automatic perimetry was performed in 2998 eyes of 1511 subjects comprising 78% of all persons born 1907–1921 and resident in a certain small area. Unreliable or abnormal tests were repeated. The average number of tests per person was 2.25. About 90% of all tests in normal eyes were performed in less than 3 min. The screening was considered negative in 2887 eyes, incomplete in 20 eyes and positive in 91 eyes (3%). Eighteen of the positives were previously unknown glaucomatous defects. There was only one unexplained “false positive”. We concluded that the method is quick, sensitive, specific and dependable. The apparatus is simple to manage and cheap to run.
