摘要
The visual illusion of a typical corona phenomenon was represented as a visual migraine aura symptom in six of 562 Migraine Art pictures, whereas another five pictures illustrated atypical variants of the said illusion. The extra edges of the corona phenomenon are commonly seen around the perceptual images of objects, but in atypical cases they can similarly surround illusory images and both elementary and complex hallucinatory images. The corona phenomenon is strongly associated with visual loss and the presence of elementary geometric hallucinations.
