White matter lesions in deep parts of brain . Around 10 in number and all less than a millimetre.
Unlikely to be direct cause of visual symptoms and more likely due to migraines suffered over many years.
One side of the visual part of brain, the occipital lobe, was marginally smaller than the other. Smaller side also had changes in QEEG. Possible implication is that blood flow to this part of brain was affected at some point and may be connected to visual symptoms.
