Method and an apparatus for testing a subject's response to visual stimuli |
摘要 |
In a method of testing a subject's response to visual stimuli, a plurality of visual stimuli are presented to the subject by means of a perimeter. After each stimulus presentation, the perimeter waits for a response from the test subject during at most a predetermined time period. The perimeter then classifies each stimulus as seen, unseen or uncertain, depending on whether a response is detected within the predetermined time period as well as on the time of receipt of any such detected response. Stimuli classified as uncertain are repeated and are not used for the calculation of threshold values.
