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.
