Abstract

PURPOSE OF REVIEW:

Impaired eye movements are frequently seen in ophthalmic and neurologic clinical practice, especially in individuals with movement disorders. Identification of the abnormal movement can aid initial diagnosis and improve understanding of the underlying disease pathophysiology. The present article reviews the ocular motor manifestations and recent research on them in common movement disorders.

RECENT FINDINGS:

Ocular motor manifestations and their pathophysiologic correlates are being defined. In particular, study of eye movements can help clarify the changing clinicopathologic spectrum of atypical parkinsonian disorders. The pathophysiology and natural history of blepharospasm are being elucidated. Recent research focuses on high-resolution imaging and other technological advances to improve the sensitivity of the ocular motility exam. Eye movements are being studied as biomarkers for diagnosis and progression in clinical care and trials.

SUMMARY:

The current review summarizes ocular motor manifestations in common movement disorders, and presents recent research investigating their cause and treatment.
