  2. Aim • Evaluate range of dynamic (objective) and static (subjective) measures of accommodation. • Relevance • Accommodative dysfunction is common oculomotor sequelae of mild traumatic brain injury (mTBI).

  3. Method • Subjects: • 12 nonstrabismic individuals with mTBI and near vision-related symptoms. • Evaluation: • Measures of accommodation before and after training. • Training: • Oculomotor training (OMT) or placebo training. • 6 wk, 2 sessions/wk, 3 h/session.

  4. Results • After OMT: • Dynamics of accommodation improved markedly. • Clinically significant increase in maximum accommodative amplitude both monoculary and binocularly. • Near vision symptoms reduced along with improved visual attention. • After placebo: • No measures changed significantly.

  5. Conclusion • These results provide evidence for significant positive effect of accommodatively based OMT on accommodative responsivity. • Such improvement suggests oculomotor learning, demonstrating considerable residual brain-visual system plasticity in the adult compromised brain.
