Abstract
Visual complaints are commonly encountered by the practicing neurologist. We review
assessment of vision loss, diplopia, and positive visual phenomena, all of which require
a thoughtful evaluation to localize disease and refine management. While many causative
entities are unlikely to cause poor visual outcomes, including dry eyes, migraine,
and congenital strabismus, others may threaten vision, life, or both, such as posterior
communicating artery aneurysms, pituitary apoplexy, or temporal arteritis. A systematic
approach to vision loss and diplopia is reviewed along with focused differential diagnoses.
