A glimpse into migraines: researchers visualize blood flow changes in the retina
Researchers at the University of California, Los Angeles (UCLA; CA, USA) have used optical coherence tomography angiography (OCTA) to visualize retinal blood flow changes during migraines, potentially uncovering a diagnostic marker for the condition.
The study investigated 37 migraine patients with aura, 30 without and 20 controls participants. The researchers identified a significant reduction in blood flow in the parafoveal region of the retina in patients with and without aura symptoms. Notably, asymmetrical blood flow correlated with the reported pain side. These findings suggest retinal blood flow changes as potential biomarkers for migraines, offering insights for clinical treatment.
