Abstract
Fluctuations in the threshold and effect of fatigue on threshold were determined by means of automated static perimetry with the Octopus in normals:
-
(1)
In 9 persons, profiles extending from the center to 30° were examined in 12 meridians with the F2 program. There is no age dependent increase of fluctuations over the age period from 28–42 years. The fluctuations are higher in the central portion than in the two other portions which is an unexpected finding.
-
(2)
Three individuals were tested 12 times in a row with F2 program during 2½ – 3½ hours. Mean fluctuation of the best performing individual was 1.59, of the worst performing individual 1.95 dB. No significant increase of fluctuation over time could be demonstrated.
-
(3)
Seven persons underwent 4 examinations by program 31 in a row. The whole examination time for each person was about 1 hour. Changes in sensitivity and fluctuations were neglegible.
For the practical test situation it may be concluded that, during a period of 1 hour, ‘fatigue’ influences neither the fluctuation nor the threshold determination in normals.
