Sustained attention analyzed by a new computerized dark adaptometer

Abstract
A new computerized dark adaptometer was developed achieving a 50% reduction of examination time. Functions were implemented for the recording of sustained attention (ie, the capacity to maintain focus and alertness over time (vigilance)). Eighteen healthy subjects were tested three times each on different days. All tests were analyzed for parameters analogous to measurements derived from continuous performance tests (ie, values for responding frequency and periods of decreased concentration). The test results were presented graphically and numerically. The automatic recording of sustained attention during clinical testing of dark adaptation is a new approach giving information on the co-operability of the patients and also information on... (More)
