Patient: Three blockages in cerebral blood vessels, dizziness, blurred right eye. After 14 days of saffron and other medications, the dizziness has been reduced, but I still feel dizzy when I walk, and my eyes are still blurred. When I rest overnight, I wake up in the morning without dizziness, and my eyes are unusually clear, as if I were not sick, but when I move around, the above symptoms are there again. I have been treating it, but the effect is not obvious. Can you give some treatment suggestions for this symptom? He Shike, Department of Neurosurgery, The Fifth Hospital of Wenzhou Medical College: It is recommended to do a comprehensive cerebrovascular examination, including ultrasound, CT or MRI cerebrovascular imaging, or even cerebral angiography, and then, according to the presence or absence of large artery stenosis, interventional or surgical treatment can be used to prevent future cerebral infarction.
