目的：评价无经验和有经验的健康青年受试者的自动动态视野检查的学习效果和可重复性。方法：对46名健康受试者(无经验组23只眼，有经验组23只眼，平均年龄25.9岁)进行前瞻性研究。使用Octopus 900视野计，使用Goldmann刺激III4e、I4e、I3e、I2e和I1e进行自动动态视野检查。受试者以3度/S的刺激速度在14个预定经脉上对每个刺激进行测试。使用三种测量方法评估学习效果的运动敏感性和测试持续时间。通过计算第二次和第三次运动敏感度的均方差(MS)和方差系数(CoV)来评估重复性。结果：只有在第一次和第二次测量之间没有经验的组才能看到学习效果。III4e和I4e的运动灵敏度分别提高了1.5度(p<；0.01)和1.1度(p=0.02)，测试持续时间减少到20.1秒(p=0.02)。在第二次和第三次测量之间，没有经验的组和有经验的组没有表现出学习效果。在重复性方面，无经验组和有经验组的I3e、I2e和I1e的运动灵敏度的MS和CoV值分别比III4e和I4e的中位数增加1.2-2.7度(p<；0.01)和1.6-13.6%(p<；0.01)。结论：新手的第一次测量结果需要仔细评估，特别是对III4e和I4e在周围区域的测量。然而，由于III4e和I4e在缺乏经验和有经验的参与者中都显示出良好的重复性，自动动态视野检查可能适合于使用更高的刺激强度来测量外围区域，如III4e和I4e。
Purpose: To evaluate the learning effect and repeatability of automated kinetic perimetry in inexperienced and experienced healthy young participants.Methods: Forty-six eyes of 46 healthy participants (23 eyes of 23 participants in the inexperienced group and 23 eyes of 23 participants in the experienced group; mean age, 25.9 years) were enrolled in this prospective study. Automated kinetic perimetry was performed using the Octopus 900 perimeter with Goldmann stimuli III4e, I4e, I3e, I2e and I1e. The participants underwent testing at 14 predetermined meridians for each stimulus with a stimulus velocity of 3 degrees /s. The learning effect was evaluated for kinetic sensitivity and test duration using three measurements. Repeatability was evaluated by calculating the mean square (MS) and coefficient of variance (CoV) of the kinetic sensitivity between the second and third measurements.Results: A learning effect was seen only in the inexperienced group between the first and second measurements. The kinetic sensitivity for III4e and I4e increased by 1.5 degrees (p < 0.01) and 1.1 degrees (p = 0.02), respectively, and the test duration decreased to 20.1 seconds (p = 0.02). There was no demonstrated learning effect in the inexperienced and experienced groups between the second and third measurements. Regarding the repeatability in the inexperienced and experienced groups, the MS and CoV values of the kinetic sensitivity for I3e, I2e and I1e increased by a median of 1.2-2.7 degrees (p < 0.01) and 1.6-13.6% (p < 0.01), respectively, compared with those of III4e and I4e.Conclusion: The results of the first measurement in the inexperienced participants require careful evaluation, especially for III4e and I4e measured in the peripheral areas. However, because III4e and I4e both showed good repeatability in inexperienced and experienced participants, automated kinetic perimetry may be suitable for measuring the peripheral area using higher stimulus intensities such as III4e and I4e.
