Micropsia, or "Lilliput sight", is an illusory phenomenon in which the size of a normally recognized object is underestimated. It is the most common form of metamorphopsia, and is most often associated with lesions of the right temporo-parietal cortex, although macular edema and optic chiasm lesions may also cause micropsia. In migraine transient micropsia may occur. Hemimicropsia, micropsia confined to one visual hemifield, has been recorded.
The entirely subjective nature of the disorder may account for the relative rarity of reports.
