A visual migraine aura occurring in isolation is called an 'acephalgic migraine.' Migraine auras vary from individual to individual--although teichopsia (zig-zag lines akin to castle battlements; see Figure 3) are thought of as being the classic migraine aura, a much wider array of symptoms may occur, including reports of 'small bright dots,' 'coloured spots of light,' along with hemianopia, scotomas, blurred vision and distortions such as 'mosaic' fractured vision or a 'heat wave' appearance.
The condition, also called acephalgic migraine or migraine aura without headache, tends to occur more frequently as people get older.
