What are the symptoms of the visual aura?
Fortification (looks like a fortified town as viewed from above) spectra or teichopsia (“seeing fortifications”), which is a jagged figure with fortification lines arranged at right angles to one another beginning from a paracentral area, may be experienced, which start in or adjacent to the center of the visual field in 50% or in the peripheral in 50% and then spread, leaving visual loss behind.
There are often scintillations, which may be white or gray or have colors similar to a kaleidoscope in a semicircle or C shape surrounding the scotoma or area of visual loss.
Scintillating scotomata are typically in one hemifield, with visual field defects beginning around fixation and spreading outward.
Some patients may describe other phenomena including zigzag lines, flashes of bright light, or heat waves.
