I'm a 22 year old healthy guy, australian. Have no known eye conditions, I do have slightly high blood pressure I've been told.
My problem is, whenever I stand up really quick my heart beats faster and if I look at a bright background, in the same spots in BOTH eyes, theres a pulsating area in sync with my blood/heartbeat. It isn't a blind spot I can see in it. This doesnt happen if I intensely exercise to raise my heartbeat, it only happens if Im laying/sitting down.
