Age-related Normative Values for the Octopus 900 Perimeter
Normal Values for the Full Visual Field, Corrected for Age- and Reaction Time, Using Semi-automated Kinetic Testing on the Octopus 900 Perimeter

The purpose of this study is to determine normal values of the visual field (VF), corrected for age- and reaction time (RT) using the Octopus 900 perimeter and semi-automated kinetic perimetry (SKP).

Device: Octopus 900 perimeter (Haag Streit AG, Koeniz, Switzerland)

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)
