William F. Hoyt and the Neuro-Ophthalmology of Superior Oblique Myokymia and Ocular Neuromyotonia.

The contributions of William F. Hoyt, MD, to the field of neuro-ophthalmology are immense. His precision in history-taking and examination skills provided the foundation to fully understand a clinical disorder-determining its underlying pathophysiology, prognosis, and management. We describe two unusual eye movement disorders, superior oblique myokymia and ocular neuromyotonia, and how Dr. Hoyt's contributions shaped our understanding of these clinical entities.
