Abstract
【Purpose】Pupil perimetry test is considered to be one of the today's promising test methods to identify visual defect. The useful point is we can take on the measurement without both the oral response of the subjects and the complicated procedure to equip electrodes. Regarding 114 eyes of the younger normal subjects, we studied the test time of pupil perimetry test by using the recorded data during the measurement.
【Method】We are to have the test time by summing each time length of inter-stimulus interval, which has always unidentified variability within the given measurement. We analyzed the feature of inter-stimulus interval.
【Results】The test time (5.6±1.5 min) was not shown normal distribution and was with positive skewness. The mild tendency we found was that both test time and percent pupil contraction deviation (as a noise component of pupil perimetry) decreased as coefficient of variance of inter-stimulus interval decreased.
【Conclusions】Both the methodology and results of our study have potential for the appropriate understanding of pupil perimetry test by both of the persons who will measure and will be measured pupillary response. Moreover our study includes the importance of the fundamental numerical material toward discussing test-retest reliability for clinical ophthalmology.
