Scintillating scotoma
（重定向自Teichopsia）
Scintillating scotoma, also called visual migraine, is the most common visual aura preceding migraine and was first described by 19th-century physician Hubert Airy (1838–1903). It either precedes a migraine headache or can occur acephalgically (without headache). It is often confused with ocular migraine, which originates in the eyeball or socket.
