Exploring the Link Between Dry Eye and Migraine: From Eye to Brain

Area of Science:

• Ophthalmology and Neurology
• Neuroscience
• Medical Research

Background:

• Dry eye disease and migraine are prevalent conditions with significant health and economic impacts.
• Emerging literature suggests a potential association between dry eye and migraine.
• Investigating this link may offer novel strategies for managing both conditions.

Purpose of the Study:

• To review the current literature on the association between dry eye and migraine.
• To explore potential shared pathophysiological mechanisms linking these two diseases.
• To discuss therapeutic strategies targeting common pathways.

Main Methods:

• Literature review of studies investigating dry eye and migraine.
• Analysis of potential shared pathophysiological mechanisms.
• Discussion of relevant therapeutic interventions.

Main Results:

• Peripheral and central sensitization are identified as key potential shared pathophysiological mechanisms.
• The review highlights the interconnectedness of ocular surface and trigeminal pathways.
• Evidence suggests a bidirectional relationship influencing disease severity.

Conclusions:

• The shared pathophysiology, particularly sensitization, provides a biological basis for the dry eye-migraine link.
• Targeting common mechanisms may offer a unified approach to treating both conditions.
• Further research is warranted to elucidate the precise relationship and optimize therapeutic strategies.
