Quantitative Oculomotor Abnormalities in Episodic and Chronic Migraine: A Cross-Sectional Comparative Study.

Migraine is a common headache disorder that may affect eye movements. Researchers studied differences in eye movement between episodic migraine (EM) and chronic migraine (CM). They included 242 migraine patients and 47 healthy controls. Among the migraine patients, 199 had EM, while 41 had CM. The study aimed to understand how these two groups differ in terms of eye movement performance. Participants completed various eye movement tasks to assess their abilities. Researchers also collected demographic data, including sex and age, along with headache-related scores. They found that both EM and CM patients showed oculomotor dysfunction compared to healthy individuals. However, the study highlighted specific differences in eye movement between EM and CM. Understanding these differences may help improve treatment options for migraine patients. Overall, the research sheds light on how migraines can affect eye function in different ways. Clinical relevance: This study highlights distinct eye movement issues in episodic versus chronic migraine, potentially guiding tailored treatment strategies for better patient outcomes.
