metamorphopsia
An anomaly of visual perception in which objects appear distorted in shape or of different size or in a different location than the actual object. It may be due to a displacement of the visual receptors as a result of inflammation, tumour or retinal detachment, it can be of central origin (e.g. migraine, drug intoxication, neurosis or brain injury), or it can be induced by recently prescribed myopic correction (e.g. micropsia) or presbyopic correction (e.g. macropsia), etc. Metamorphopsia can be detected with an Amsler chart. See spasm of accommodation; dysmegalopsia; macular hole; pelopsia; teleopsia.
