Slideshow Project DOI: 10. 1682/JRRD. 2012. 0235 JSP • Aim – Evaluate range of dynamic and static vergence responses in individuals with mild traumatic brain injury (m. TBI) having near vision symptoms. • Relevance – Following acute phase and natural recovery period, most individuals with m. TBI having vision-related symptoms are diagnosed with ≥ 1 oculomotor dysfunctions. This article and any supplementary material should be cited as follows: Thiagarajan P, Ciuffreda KJ.

Method Slideshow Project DOI: 10. 1682/JRRD. 2012. 0235 JSP • Participants: – 12 individuals with m. TBI and near vision symptoms. • Crossover design: – Before and after oculomotor training (OMT) and placebo (P) training.

Results Slideshow Project DOI: 10. 1682/JRRD. 2012. 0235 JSP • After OMT: – Increased peak velocity for convergence and divergence. – Correlation between increased peak velocity and increased clinically based vergence prism flipper rate. – Reduced steady-state response variability for convergence. – Improved maximum amplitude of convergence, relative fusional amplitudes, and near stereoacuity. – Reduced symptoms – Markedly improved visual attention. • After P training: – No significant changes.

Conclusion Slideshow Project DOI: 10. 1682/JRRD. 2012. 0235 JSP • Most aspects of vergence eye movements significantly improved after OMT. – Demonstrates considerable residual brain plasticity via oculomotor learning. • Improved vergence positively affected near work-related symptoms and visual attention.
