Retinal and Choroidal Microvascular Changes Across the Migraine Attack Cycle: A Systematic Review and Exploratory Quantitative Synthesis.

Migraine is a common headache disorder that affects many people. Researchers wanted to understand if certain eye changes happen during or between migraine attacks. They looked at studies using a technique called optical coherence tomography angiography (OCTA). This method helps visualize blood vessels in the eye. The researchers found seven studies that met their criteria. Out of these, three studies compared eye changes during a migraine to those between attacks. They discovered that eye changes varied during different phases of a migraine. Specifically, there was a notable decrease in blood flow in certain areas of the eye during attacks. This suggests that migraines might cause temporary changes in eye blood vessels. Understanding these changes could help in managing migraines better. More research is needed to fully understand the relationship between migraines and eye health. Clinical relevance: This research highlights potential eye changes during migraine attacks, which may improve diagnosis and treatment strategies for patients suffering from migraines.
