In a groundbreaking study published in the journal Headache, researchers have uncovered how changes in retinal blood flow may play a crucial role in influencing visual symptoms in migraine patients. The findings could provide an essential biomarker for diagnosing and understanding migraines.
Using the advanced, non-invasive imaging technique known as optical coherence tomography angiography (OCTA), the research team examined retinal blood vessel changes in 37 migraine patients who experience aura symptoms, 30 migraine patients without aura, and a control group of 20 healthy individuals.
The study found a significant decrease in retinal blood flow during migraine attacks in both groups of patients. However, those with aura symptoms exhibited lower blood flow in specific retinal regions compared to patients without aura, indicating a possible physiological distinction between the two types of migraines.
Moreover, the research identified an association between asymmetrical blood flow in the retina and the side of the head where migraine patients feel pain. This connection suggests a deeper link between retinal circulation and migraine-related visual disturbances, offering valuable insights into the neurological origins of the condition.
These findings could pave the way for new diagnostic approaches and potential treatments targeting retinal blood flow regulation in migraine sufferers.
