central macropsia

central macropsia
   The term central macropsia comes from the Greek words kentron (centre of a circle), makros (large), and opsis (seeing). It refers to a visual distortion in which objects and stimuli are perceived as disproportionally large, but only in the central field of vision. Because objects and stimuli perceived in the periphery of the visual field retain their normal proportions, central macrop-sia yields an image similar to that perceived through a birds-eye lens. The introduction of the French term macropsie centrale is attributed to the French psychologist Charles Binet-Sanglé (1868-1941). Central macropsia is classified as a variant of *macropsia, which is in turn classified as a * metamorphopsia.
