Hello,
It might be related to a problem with the blood vessels that supply the part of the brain responsible for processing the visual information. This is the occipital
cortex and it is supplied from vertebrobasilar arteries.
These symptoms you describe can be a result of an obstruction of blood flow due to compression of a
vertebral artery and this will decrease the blood supply for these specific areas of the brain.
This can be a mechanical compression and the compression might be present in a specific position of the head depending on what is causing the compression.
The most common causes are vertebral problems like cervical bone spurs, bony malformations, disk rupture, abnormal muscle insertions,
arthritis and dislocations.
You should consult a physician as soon as possible and get examined. You may need to run some tests like:
-Transcranial Doppler
-magnetic resonance angiography
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Iven Romic Rommstein, General Surgeon
