The Cause of Ocular Migraines
There are various theories that attempt to explain the cause of an ocular migraine. Ocular migraines are a type of migraine with aura. The defining factor of ocular migraine is that the visual aura affects both eyes.
Many medical professionals believe that an ocular migraine occurs due to an electrical wave or body chemical moving across the visual cortex during a migraine. The result is visual disturbances such as floating spots in the line of vision, flashes of light, zigzagging patterns moving across the field of vision or other apparitions such as flashing lights.
The visual effects don’t usually last for a long period of time, but they can have debilitating effects as they make it hard to do things like computing or driving a car. People that experience any migraine with an aura should tell their doctors as these types of migraines indicate the individual is at higher risk for a stroke.
