Isolated Ocular Ipsipulsion as a Clue to Central Vertigo in Lateral Medullary Infarction.

ABSTRACT: Background: Horizontal conjugate eye deviation (HCED) is typically associated with supratentorial strokes affecting the frontal eye fields and associated pathways. However, a rare form of HCED, ocular ipsipulsion, is caused by a lateral medullary lesion. The presumed mechanism involves disruption of decussating olivocerebellar fibers, leading to an imbalance in vestibular nuclei activity. Purpose: To report a case of isolated ocular ipsipulsion as a diagnostic clue to central vertigo. Research Design: Case report. Study Sample: An 82-year-old man with a right lateral medullary infarction. Data Collection: Neurological examination and brain magnetic resonance imaging (MRI) were performed. Ocular findings were documented through bedside observation and vide
