Vision change
Question
From six years I have change and disorder in my vision, I had eyes exam and it’s normal, I had brain MRI and it’s normal, i had blood tests and neck doppler for arteries and it’s normal. Now I want to do exam for my brain arteries , it’s better to do MRA OR DSA and do they both have the same results? Do they both rule out any narrowing in arteries causing vision change?
