A new study conducted by researchers at the University of California, USA, revealed that differences in blood flow in the retina may explain why some… Migraine patients With visual disturbances, the results may provide a long-awaited visual sign of migraine, which doctors may use to aid in the medical treatment of this condition, according to what was published by the “hindustantimes” website.
The study confirmed that patients with migraine often suffer from symptoms such as pain around the eye, sensitivity to light, blind spots, and blurred vision, and the mechanisms behind these symptoms are not well understood.
The study indicated that researchers at the University of California used a non-invasive imaging technique, known as optical coherence tomography angiography, or OCTA, to visualize changes in the blood vessels in the retina of migraine patients.
The study explained that imaging was performed on 37 patients with migraine with aura symptoms, 30 patients with migraine without aura symptoms, and 20 healthy patients in a control group.
Researchers at the University of California have confirmed that blood flow decreases in the retina during migraine attacks for both migraine patients with and without aura symptoms. However, patients with aura symptoms have been found to have decreased blood flow in certain areas. of the retina compared to patients without aura symptoms. Asymmetric blood flow in the retina was also associated with which side of the head migraine patients experience. The findings could indicate why some patients develop visual symptoms and may represent a biomarker for migraine attacks.
