A new study suggests pattern visual-evoked potentials (VEP) could help clinicians identify patients with convergence insufficiency and a history of concussion. Researchers used pattern VEP to test 79 patients based on a diagnosis of convergence insufficiency/binocular dysfunction—35 of whom reported a history of concussions. They found two different pattern VEP models discriminated between concussed and nonconcussed groups. With further research, VEP could become a valuable diagnostic tool for these patients.
