I get visual auras related to migraines. I was curious – are the auras happening in the eyes or in the brain?

  1. I also have migraines and I asked my eye doc that same question. He said that the auras I have do NOT come from my eyes. Something about the pressure on the veins in your head and behind the eye.

  2. The major problem in visual perception is that what people see is not simply a translation of retinal stimuli (i.e., the image on the retina). Thus people interested in perception have long struggled to explain what visual processing does to create what we actually see.
    If I had to make a guess it would be the result of the brians visual processing centers, and not of the eyes themselves. Think of the eyes as more of an internet cable bringing the information into your computer so it can be looked over by the processor in your computer. I have listed an article below to a site which may provide more information. For now I can give you a little more information on vision in the brain.
    The occipital lobe is the visual processing center of the mammalian brain, containing most of the anatomical region of the visual cortex. The occipital lobes are the smallest of four true lobes in the human brain. Located in the rearmost portion of the skull, the occipital lobes are part of the forebrain structure.

  3. They’re happening in the brain. Migraines are caused by reduced blood flow in the portion of the brain that is towards the back of the brain. The back part of the brain is also related to vision.
