Abstract
A visual field test was performed on 100 volunteers to study learning or fatigue effects during one session. The test was carried out with the help of the Octopus program J1, which measures the threshold 12 times at 3 test locations. In the majority of cases the sensitivity was quite stable during the session. We noted no difference between trained and untrained subjects or between normal and pathological eyes. However, patients with refractive errors, especially myopes, revealed a larger learning effect than did emmetropes.
