Blood flow changes in the eyes could influence visual symptoms of migraines

A study conducted by UCLA Health researchers found that changes in blood flow in the retina could be responsible for visual symptoms experienced by some migraine patients. The study used a non-invasive imaging technique to visualize changes in retinal blood vessels during and between migraine attacks. The findings showed that blood flow decreases in the retina during migraine attacks for both patients with and without aura symptoms. However, patients with aura symptoms were found to have lower blood flow in certain areas of the retina. The study suggests that these changes in blood flow could be an observable marker for migraines. This research has been published in Headache: The Journal of Head and Face Pain.
