Ocular Flutter in Hyperosmolar Hyperglycemic State during Treatment of Malignant Cerebral Edema

ABSTRACT

Ocular flutter (OF) is a rare eye movement disorder with horizontal saccadic oscillations without inter-saccadic intervals. The OF can occur in various clinical settings. A 83-year-old female showed the OF in hyperosmolar hyperglycemic state (HHS) following malignant cerebral infarction. The pathophysiology of the OF is still unclear, but this case provides a new information that the OF can occur in the context of toxic-metabolic state such as HHS.
