眼跳对于最佳视力是必要的。人们对儿童眼跳知之甚少。我们使用全红外眼动仪记录了 39 名 8-19 岁儿童的眼跳情况。参与者以不可预测的时间间隔对视觉目标进行扫视，水平移动 10 度或 15 度，垂直移动 5 度或 10 度。扫视潜伏期随着年龄的增加而显着减少，而扫视增益和峰值速度不随年龄变化。儿童的扫视增益和峰值速度与报告的成人值相似。这意味着负责使眼跳准确而快速的神经回路已经成熟。随着大脑的成熟，扫视潜伏期会缩短。 (c) 2005 Elsevier Ltd. 保留所有权利。
Saccades are necessary for optimal vision. Little is known about saccades in children. We recorded saccades using all infrared eye tracker in 39 children, aged 8-19 years. Participants made saccades to visual targets that stepped 10 degrees or 15 degrees horizontally and 5 degrees or 10 degrees vertically at unpredictable time intervals. Saccadic latency decreased significantly with increasing age, while saccadic gain and peak velocity did not vary with age. Saccadic gains and peak velocities in children are similar to reported adult values. This implies maturity of the neural circuits responsible for making saccades accurate and fast. Saccade latency decreases as the brain matures. (c) 2005 Elsevier Ltd. All rights reserved.
