Eye Movement in Neurological Disorders

Eye movements are an important aspect of neurological clinical assessment, as abnormal eye movements can indicate underlying neurological and disease processes. Eye-tracking recordings are also often performed following neurological injury or disease in order to study the underlying neurological mechanisms involved in controlling eye movement. The present chapter will review some major neurological conditions (Parkinson’s disease, Huntington’s disease, dementia, stroke, multiple sclerosis, and traumatic brain injury) that impact eye movements and the abnormalities that accompany them. The subjective clinical and objective examinations of eye movements are discussed and described in relation to neurological conditions.
