teichopsia

The scintillating scotoma of migraine. A slowly-expanding area of visual loss with a shimmering, jagged border that lasts for about 20 minutes and then fades away leaving normal vision. Teichopsia may or may not be followed by headache. Also known as ‘fortification spectra’, hence the Greek derivation from teichos , a wall, and ops , vision. There is anecdotal evidence that teichopsia is commoner in academics and intellectuals than in the general population.
