What are photopsia and fortification spectra?

ANSWER

The vision changes that can occur during an aura may involve a complex array of lights and images that appear before your eyes. Photopsia is the medical term for 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.
