vertical heterophoria, tbi, traumatic brain injury, concussion

The study identified vertical heterophoria in a group of TBI patients with postconcussive symptoms. The treatment of vertical heterophoria with individualized prismatic spectacle lenses resulted in a significant reduction in subjective symptom burden and a relative reduction in VHS-Q score. It suggested that vertical heterophoria can be acquired as a result of traumatic brain injury.
