OBJECTIVE
To identify a form of binocular vision dysfunction (vertical heterophoria) in a traumatic brain injury (TBI) population and to assess the effect of individualized prismatic spectacle lenses on postconcussive symptoms.
CONCLUSIONS
- TBI can cause VH.
- Treatment with prismatic lenses led to a 72% subjective reduction of post-concussive symptoms.
- Treatment lasted on average 3 1/2 months.
