What are photopsia and fortification spectra with migraine headaches?

ANSWER

Some people with migraines get a visual disturbance called an aura before or along with their headaches. Photopsia is the medical term for an aura with flashes of light.

Fortification spectra are more complicated images that can float in your vision during a migraine. These get their name from their resemblance to an aerial view of an intricately built fort.
