This review provides an approach to selecting an appropriate imaging study and interpreting the results. MRI and CT are the imaging studies most commonly employed in neuro-ophthalmology. Each modality has unique strengths that make it particularly suitable in certain clinical situations. In the current practice of neuro-ophthalmology, the clinician must be familiar with the uses and limitations of neuroimaging studies so they can be used appropriately to improve diagnostic accuracy.
