Method: A review of the vestibular system and the vestibular ocular reflex as it relates to dynamic visual acuity.

Results: Ten patients with asthenopic symptoms and convergence insufficiency were tested with dynamic visual acuity. None were found to have a positive test despite a complaint of dizziness, indicating the lack of vestibular involvement.
