We used the following six combinations of Goldmann8,1 stimulus size, stimulus luminance and angular velocity: V4e (64mm², 103', 320cd/m²) at 5°/s, III4e (4mm², 25.7', 320cd/m²) at 5°/s, I4e (0.25mm², 6.45', 320cd/m²) at 2°/s (for the assessment of the blind spot), I3e (0.25mm², 6.45', 100cd/m²) at 5°/s, I2e (0.25mm², 6.45', 32cd/m²) at 3°/s, I1e (0.25mm², 6.45', 10cd/m²) at 3°/s, I1a (0.25mm², 6.45', 4cd/m²) at 2°/s . The peripheral five isopters, consisting of 24 vectors (every 15° meridian), were presented in random order, while the innermost isopter (I1a) consisted of 12 vectors (every 30° meridian) |
