A range of dynamic and static vergence responses were evaluated in 12 individuals with mild traumatic brain injury (age: 29 +/- 3 yr) having near vision symptoms. All measures were performed in a crossover design before and after oculomotor training (OMT) and placebo (P) training. Following OMT, peak velocity for both convergence and divergence increased significantly. Increased peak velocity was significantly correlated with increased clinically based vergence prism flipper rate. Steady-state response variability for convergence reduced significantly following OMT. The maximum amplitude of convergence, relative fusional amplitudes, and near stereoacuity improved significantly. In addition, symptoms reduced significantly, and visual attention improved markedly. None of the measures were found to change significantly following P training. The significant improvement in most aspects of vergence eye movements following OMT demonstrates considerable residual brain plasticity via oculomotor learning. The improved vergence affected positively on nearwork-related symptoms and visual attention.
对12名有近视症状的轻度创伤性脑损伤患者（年龄：29±3岁）的一系列动态和静态聚散反应进行了评估。所有测量均采用交叉设计，在眼动训练（OMT）和安慰剂（P）训练前后进行。OMT后，集合和发散的峰值速度均显著增加。峰值速度的增加与基于临床的聚散棱镜翻转率的增加显著相关。OMT后，集合的稳态反应变异性显著降低。集合的最大幅度、相对融合幅度和近立体视锐度显著改善。此外，症状显著减轻，视觉注意力明显提高。P训练后未发现任何测量值有显著变化。OMT后聚散眼球运动的大多数方面的显著改善表明，通过眼动学习，大脑具有相当大的残余可塑性。聚散功能的改善对与近工作相关的症状和视觉注意力产生了积极影响。
