Nystagmus

“Never write about nystagmus, it will lead you nowhere.”

-Hermann Wilbrand

Neurology Primer

Few topics in orthoptics and neuro- ophthalmology instill as much unease as nystagmus. Clinical confusion may be the result of exam findings that are difficult to interpret, coupled with complex and incompletely understood neuroanatomic pathways. Eye movement recordings have allowed definition of 47 types of nystagmus and new insights into their pathophysiology. 

This neurology primer will include the anatomy, physiology, pathophysiology, testing, interpretation, and treatment of nystagmus. Dr. Traster walks you through the most clinically relevant forms of nystagmus that you should know for your everyday practice. After completing this course you will be ready to better assess and manage patients ranging from post-concussion, dizziness, motion sensitivity, neck pain/stiffness, headaches, dysautonomia, and more.
