Accommodative dysfunction is a common oculomotor sequelae of mild traumatic brain
injury (mTBI). This study evaluated a range of dynamic (objective) and static
(subjective) measures of accommodation in 12 nonstrabismic individuals with mTBI
and near vision-related symptoms before and after oculomotor training (OMT) and
placebo (P) training (6 wk, two sessions per week, 3 h of training each).
Following OMT, the dynamics of accommodation improved markedly. Clinically, there
was a significant increase in the maximum accommodative amplitude both
monocularly and binocularly. In addition, the near vision symptoms reduced along
with improved visual attention. None of the measures were found to change
significantly following P training. These results provide evidence for a
significant positive effect of the accommodatively based OMT on accommodative
responsivity. Such improvement is suggestive of oculomotor learning,
demonstrating considerable residual brain-visual system plasticity in the adult
compromised brain.
