Convergence insufficiency as a predictor of poor prognosis after acute mild traumatic brain injury
This prospective study evaluated the feasibility of screening for convergence insufficiency (CI) symptoms in emergency department patients with mild traumatic brain injury using the Convergence Insufficiency Symptom Survey (CISS). Higher CISS scores were associated with adverse outcomes including post-concussive symptoms and hospital admission, suggesting oculomotor assessment may help identify patients at risk for poor recovery after mTBI.
