This is a case of migraine, presenting with the interesting visual aura of a ‘kaleidoscope’: waves with flickering movements made up of a variety of colors (red, blue, green, yellow), commencing laterally and spreading superiorly in the visual field of the left eye. This description is quite similar to a fortification spectrum, which usually expands and spreads in a C-shape fashion over one side of the visual field. Several different possible pathophysiological explanation are shared as well as the common differential diagnoses. In the work up of a patient with visual aura migraine, a comprehensive and detailed history is important, together with the appropriate investigations, in order not to miss any serious syndromes, including stroke syndromes and epilepsy.
