Anomaly of visual perception in which objects appear smaller than they actually are. It may be due to a retinal disease in which the visual cells are spread apart, or to paresis of accommodation or to uncorrected presbyopia, or to the recent wear of either base-out prisms or a correction for myopia, etc. See dysmegalopsia; macropsia; metamorphopsia.
