Abstract:
Normative visual field area, feasibility and repeatability using (Octopus) semi-automated kinetic perimetry are reported in 221 healthy volunteers aged 5-22 years. I4e and I2e stimuli assessed the visual field at 5°/second (°/s) or 3°/s. Blind spot was assessed with I2e at 2°/s. Reliable visual fields were plotted in 23% of participants <10 years, 64% of 10-12-year-olds, and 98% aged 13-22 years. Visual field areas were unchanged with age using 5°/s, but increased using 3°/s for I2e (p = 0.028). Blind spot area was unchanged with age. Reaction times reduced with age (p < 0.004). There was no learning effect. A test speed of 5°/s is recommended.
